How to add WSDL, XSD (and possibly other files) to WAR - maven

I have a very simple pom.xml that generates a fully working web service if deployed locally (Tomcat 7). This is its <build> section:
<build>
<finalName>${artifact.id}</finalName>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-codegen-plugin</artifactId>
<version>2.3.1</version>
<executions>
<execution>
<id>generate-sources</id>
<configuration>
<sourceRoot>${basedir}/target/generated/src/main/java</sourceRoot>
<wsdlOptions>
<wsdlOption>
<wsdl>${basedir}/src/main/wsdl/mywebservice.wsdl</wsdl>
<extraargs>
<extraarg>-impl</extraarg>
<extraarg>-verbose</extraarg>
</extraargs>
<wsdlLocation>${basedir}/src/main/wsdl/mywebservice.wsdl</wsdlLocation>
</wsdlOption>
</wsdlOptions>
</configuration>
<goals>
<goal>wsdl2java</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>1.5</version>
<executions>
<execution>
<id>add-source</id>
<phase>generate-sources</phase>
<goals>
<goal>add-source</goal>
</goals>
<configuration>
<sources>
<source>${basedir}/target/generated/src/main/java</source>
</sources>
</configuration>
</execution>
<execution>
<id>attach-artifacts</id>
<phase>package</phase>
<goals>
<goal>attach-artifact</goal>
</goals>
<configuration>
<artifacts>
<artifact>
<file>${basedir}/src/main/wsdl/mywebservice.wsdl</file>
<type>wsdl</type>
</artifact>
<artifact>
<file>${basedir}/src/main/xsd/myschema.xsd</file>
<type>xsd</type>
</artifact>
</artifacts>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
The reason it only works if deployed locally and not when deployed to a remote server is because the remote server cannot find the .wsdl and the .xsd files in development source directories ${basedir}/target/generated/src/main/ and they are also nowhere to be found in the WAR file.
Apparently, I am missing something in my pom.xml that would make Maven add or attach those files to the WAR.
I tried the attach-artifact goal (as quoted above) but it only copies the files to my local (development) .m2 repository, not to the WAR file.
How do I add or attach files to the actual .war file to be deployed?

I solved the mystery.
Posting the answer here in case another newbie to Maven (plus CXF?) encounters this problem:
It turns out that the attach-artifact execution is totally unneeded and is a shot in the wrong direction.
All I had to do was to add at the top of the <build> section, just before <plugins> the following:
<resources>
<resource>
<directory>src/main/wsdl</directory>
</resource>
<resource>
<directory>src/main/xsd</directory>
</resource>
</resources>
That's all. Maven then automagically places all files in those directories in WEB-INF/classes/.

Generated sources being compiled twice

Using Eclipse Luna with m2eclipse, I have a parent Maven project (facturas_root) and two Maven modules inheriting from it (sharepoint_ws and api_sharepoint).
sharepoint_ws was to be used only to generate JAXWS classes to connect to the Sharepoint WebServices, so I downloaded the related WSDL and included those as resources of the project. At generate-sources phase, it works correctly and generates the sources in target\generated-sources\ws-consume\mypackage\.
Now, the issue is that I made api_sharepoint import the sharepoint_ws dependency, but it does not detect any class. I assumed that it was because the generated classes were not at src/main/java, so I added a plugin to copy them there. Now, the problem is that at the compile phase of sharepoint_ws, it finds twice the source file of each class and throws an error.
My pom.xml -> build

In order to try to exclude target/generated-sources I have addded this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<executions>
<execution>
<id>default-compile</id>
<phase>compile</phase>
<configuration>
<excludes>
<exclude>**/target/generated-sources/*.java</exclude>
</excludes>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
As stated above, I do comment the "copy" plugin, the module depending on sharepoint_ws does not have any ot its classes available; I do use it I get errors in the tune of
[ERROR] /C:/Users/s004256/workspace/facturas_root/sharepoint_ws/src/main/java/es/ssib/otic/facturas/sharepoint_ws/DeleteList.java:[34,8] duplicate class: es.ssib.otic.facturas.sharepoint_ws.DeleteList
for each generated list.
In the first place, I recommend you'd better declare target/generated-sources as a source folder, instead of copying files here and there:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<id>add-source</id>
<phase>initialize</phase>
<goals>
<goal>add-source</goal>
</goals>
<configuration>
<sources>
<source>${project.build.directory}/generated-sources</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>
This should be enough to make Maven compile the target/generated-sources/*.java and package them all in the library, and also for Eclipse to recognize target/generated-sources as a source directory (after you execute Maven/Update Project).
By the way: You should take care of binding the plugins to a phase in the correct order: If you bound all tasks to "generate-sources", you have no gurantee about in which order will they be executed. And the same goes for the "compile" phase: You have to set properly the source folders, with its inclusions and exclusions, before the compile phase.
Take a look a the Default Maven Lifecycle and try to chose different, sequential phases for your tasks.

maven-deploy-plugin repository

I want to deploy a file using the maven-deploy-plugin. Currently i have the following in my pom:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-deploy-plugin</artifactId>
<version>2.7</version>
<executions>
<execution>
<id>deploy-features-xml</id>
<phase>deploy</phase>
<goals>
<goal>deploy-file</goal>
</goals>
<configuration>
<repositoryId>${project.distributionManagement.snapshotRepository.id}</repositoryId>
<url>${project.distributionManagement.snapshotRepository.url}</url>
<groupId>${project.groupId}</groupId>
<artifactId>${project.artifactId}</artifactId>
<version>${project.version}</version>
<file>features.xml</file>
</configuration>
</execution>
</executions>
</plugin>
I want to change between the snapshot and release repository based on the version. If the project version is 1-SNAPSHOT the file should be deployed to the snapshot repository, if the project is version 1.0 the file should be deployed to the release repository. But the maven-deploy-plugin hard codes it?
This behaviour is already given by default. But you should use a repository manager. You can simple deploy an artifact via mvn deploy usually having a SNAPSHOT release will go into the SNAPSHOT repository in case of a release it will go to the release repository.
The solution that I ended up with was to use the build-helper-maven-plugin and the maven-resources-plugin. This setup means that along with the jar and pom and project will deploy an xml file that can be references in the maven repo as project/xml/features.
Relevant pom plugins:
<plugin>

Rename directory while building war-file with Maven

Question
Overall Goal
I want to build a Java WebApp (war file) where folders containing static content have a version number append to it for cachability. Renaming should happen automatically during build.
Details
The WebApp is already structured in a way that all static content is grouped together inside folders:
/lib -> All JavaScript libraries, eg /lib/angular-1.0.3 (source at src/main/webapp)
/app -> My Own Code, at the moment /app/myApp (source at src/main/webapp)
/api -> all dynamic servlets (source at src/main/java)
index.jsp -> host page that bootstraps the WebApp
Everything starting with /api and index.jsp is dynamic and not cachable at all.
Everything starting with /lib is static and versioned, thus we can set an expires header of 'access + 12 month'. Content changes require a new version number. This is easy with libraries, as they don't change much an the version number is hardcoded.
Since my own app (built with AngularJS) is also static, I want to set its expires header to 'access + 12 month', too. To do so, I need to add the current version number from Maven to the end of the folder name, thus turning /app/myApp from the source directory to /app/myApp-1.2.3 in the target directory / final war file.

I am looking for a way to copy all ressources to the target-directory, run yuicompressor, update the links and rename app/myApp to app/myApp-x.y.z
Compressing and updating the links already, but I can't find a way to rename my own app at build time.
Thanks

I think you can do it by configuring a <webResources> element in your maven-war-plugin config.
Doing something like this should work
<configuration>
<!-- this exclude the directory to rename from the default copy resources procedure -->
<warSourceExcludes>app/myApp/**</warSourceExcludes>
<!-- this will do the renaming :
i.e. we specify the source directory relative to pom.xml
and the target directory relative to root -->
<webResources>
<resource>
<directory>src/main/webapp/app/myApp</directory>
<!-- override the destination directory for this resource -->
<targetPath>app/myApp-${project.version}</targetPath>
</resource>
</webResources>
</configuration>
EDIT
I'm not used to work with yucompressor plugin but it seems that you can easily change the output directory through <outputDirectory> element:
<outputDirectory>${project.build.directory}/${project.build.finalName}/app/myApp-${project.version}/js/all.min.js</outputDirectory>
If all your code is in all.min.js (I think that's what the yucompressor do, but I'm not sure) : then you don't need the <webResources> section in the war plugin, but you have to keep <warSourceExcludes>app/myApp/**</warSourceExcludes> to avoid duplication.
EDIT 2
As an answer to your comment.
Try the following:
use yucompressor for *.css and *.js as indicated in previous EDIT
exclude /myapp from usual war-plugin copy resources procedure using <warSourceExcludes>app/myApp/**</warSourceExcludes>
use a webResources section to include all you non *.js and non *.css to myApp-${project.version}:
<webResources>
<resource>
<directory>src/main/webapp/app/myApp</directory>
<excludes>
<exclude>**/*.js</exclude>
<exclude>**/*.css</exclude>
</excludes>
<!-- override the destination directory for this resource -->
<targetPath>app/myApp-${project.version}</targetPath>
</resource>
</webResources>

yuicompressor maven plugin and maven-war-plugin

I've been struggling with getting this plugin to play nicely with the maven-war-plugin for a couple of hours now and I thought it was time to ask for help. I have the plugin defined as follows:
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>yuicompressor-maven-plugin</artifactId>
<version>1.3.0</version>
<executions>
<execution>
<id>compressyui</id>
<phase>process-resources</phase>
<goals>
<goal>compress</goal>
</goals>
<configuration>
<nosuffix>true</nosuffix>
<warSourceDirectory>${basedir}/WebContent</warSourceDirectory>
<jswarn>false</jswarn>
</configuration>
</execution>
</executions>
</plugin>
If I remove nosuffix=true then I can see the compressed/minified -min.js files get into the war as expected, but with this flag on they are being overwritten by the maven-war-plugin (I'm assuming) when it builds the war file. I really need the file names to remain the same though ... does anyone have an idea of what I need to change in order to use the same filenames and still get the minified versions into the final war?
OK. I finally figured this out. You need to define a <webappDirectory> in the yuicompressor plugin that can then be referenced as a <resource> in the maven-war-plugin. In the example below I'm using <directory>${project.build.directory}/min</directory>
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>yuicompressor-maven-plugin</artifactId>
<version>1.3.0</version>
<executions>
<execution>
<id>compressyui</id>
<phase>process-resources</phase>
<goals>
<goal>compress</goal>
</goals>
<configuration>
<nosuffix>true</nosuffix>
<warSourceDirectory>${basedir}/WebContent</warSourceDirectory>
<webappDirectory>${project.build.directory}/min</webappDirectory>
<jswarn>false</jswarn>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<artifactId>maven-war-plugin</artifactId>
<executions>
<execution>
<id>default-war</id>
<phase>package</phase>
<goals>
<goal>war</goal>
</goals>
<configuration>
<warSourceDirectory>${basedir}/WebContent</warSourceDirectory>
<encoding>UTF-8</encoding>
</configuration>
</execution>
</executions>
<configuration>
<warSourceDirectory>${basedir}/WebContent</warSourceDirectory>
<encoding>UTF-8</encoding>
<webResources>
<resource>
<directory>${project.build.directory}/min</directory>
</resource>
</webResources>
</configuration>
</plugin>
Just configure 'warSourceExcludes' on the WAR plugin.
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.4</version>
<configuration>
<warSourceExcludes>**/*.css,**/*.js</warSourceExcludes>
</configuration>
</plugin>
I would like to add the configuration which worked for me:
First, to fix m2e complaining about the 'Plugin execution not covered by lifecycle' I added the following in the parent pom taken from this post:
<pluginManagement>
<plugins>
<!--This plugin's configuration is used to store Eclipse
m2e settings only. It has no influence on the Maven build itself. -->
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
<pluginExecutions>
<pluginExecution>
<pluginExecutionFilter>
<groupId>net.alchim31.maven</groupId>
<artifactId>yuicompressor-maven-plugin</artifactId>
<versionRange>[1.0.0,)</versionRange>
<goals>
<goal>compress</goal>
</goals>
</pluginExecutionFilter>
<action>
<execute />
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
</configuration>
</plugin>
</plugins>
</pluginManagement>
Then in the war pom I put:
<build>
<plugins>
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>yuicompressor-maven-plugin</artifactId>
<version>1.4.0</version>
<executions>
<execution>
<goals>
<goal>compress</goal>
</goals>
<configuration>
<linebreakpos>300</linebreakpos>
<excludes>
<exclude>**/*-min.js</exclude>
<exclude>**/*.min.js</exclude>
<exclude>**/*-min.css</exclude>
<exclude>**/*.min.css</exclude>
</excludes>
<nosuffix>true</nosuffix>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.4</version>
<configuration>
<warSourceExcludes>**/*.css,**/*.js</warSourceExcludes>
</configuration>
</plugin>
</plugins>
</build>
This generates the minified css and js files in the project build target directory while excluding the original files.
I hope this saves someone time.
this is my configuration, and it works fine in my maven web project:
<!-- js/css compress -->
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>yuicompressor-maven-plugin</artifactId>

<nosuffix>true</nosuffix>
</configuration>
<executions>
<execution>
<id>compress_js_css</id>
<phase>process-resources</phase>
<goals>
<goal>compress</goal>
</goals>
</execution>
</executions>
</plugin>
<!-- war -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.3</version>
<configuration>
<webResources>
<resource>
<directory>${project.build.directory}/${project.build.finalName}/resources</directory>
<targetPath>/resources</targetPath>
<filtering>false</filtering>
</resource>
</webResources>
<webXml>src/main/webapp/WEB-INF/web.xml</webXml>
</configuration>
</plugin>
The approach I use is a bit different.
First, I've configured my IDE to run mvn process-resources before the compilation/packaging. This way the files are created before the war is assembled.
It is very important to set <nosuffix>false</nosuffix> and <outputDirectory>${basedir}/src/main/resources/</outputDirectory> so the files can be created in the same directory without replacing your original source files.
<plugin>
<groupId>net.alchim31.maven</groupId>

<version>1.3.2</version>
<configuration>
<preProcessAggregates>false</preProcessAggregates>
<excludes>

<exclude>**/*.min.js</exclude>
<exclude>**/*-min.css</exclude>
<exclude>**/*.min.css</exclude>
</excludes>
<jswarn>false</jswarn>
<nosuffix>false</nosuffix> <!-- VERY IMPORTANT WILL REPLACE YOUR FILES IF YOU SET nosuffix TO TRUE OR DONT SET IT AT ALL -->
<outputDirectory>${basedir}/src/main/resources/</outputDirectory> <!-- by default the plugin will copy the minimized version to target directory -->
<failOnWarning>false</failOnWarning>
</configuration>
<executions>
<execution>
<id>compress_js_css</id>
<phase>process-resources</phase>
<goals>
<goal>compress</goal>
</goals>
</execution>
</executions>
</plugin>
As Jakob Kruse say, you must deal with the *.js, but no *.min.js, so my configurations is below, please notice the use of %regex[] :
<plugin>

How to place the output jar into another folder with maven?

I'd like to place my output jar and jar-with-dependencies into another folder (not in target/ but in ../libs/).
How can I do that?
You can use the outputDirectory parameter of the maven-jar-plugin for this purpose:
<project>
...
<build>
<plugins>
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.3.1</version>
<configuration>
<outputDirectory>../libs</outputDirectory>
</configuration>
</plugin>
...
</plugins>
</build>
...
</project>
But as cdegroot wrote, you should probably better not fight the maven way.
If you want to copy the artifact into a directory outside your project, solutions might be:
maven-jar-plugin and configure outputDirectory
maven-antrun-plugin and copy task
copy-maven-plugin by Evgeny Goldin
Example for the copy-maven-plugin is:
<plugin>
<groupId>com.github.goldin</groupId>
<artifactId>copy-maven-plugin</artifactId>
<version>0.2.5</version>
<executions>
<execution>
<id>deploy-to-local-directory</id>
<phase>install</phase>
<goals>
<goal>copy</goal>
</goals>
<configuration>
<skipIdentical>false</skipIdentical>
<failIfNotFound>false</failIfNotFound>
<resources>
<resource>
<description>Copy artifact to another directory</description>
<targetPath>/your/local/path</targetPath>
<directory>${project.build.directory}</directory>
<includes>
<include>*.jar</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
Another way would be maven-resources-plugin (find the current version here):
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.0.2</version>
<executions>
<execution>
<id>copy-files-on-build</id>
<phase>package</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${basedir}/[TO-DIR]</outputDirectory>
<resources>
<resource>
<directory>[FROM-DIR]</directory>
<!--<include>*.[MIME-TYPE]</include>-->
<filtering>false</filtering>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
I would do it this way:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.8</version>
<executions>
<execution>
<phase>install</phase>
<configuration>
<target>
<copy file="target/${project.artifactId}-exec.jar" tofile="../../docker/${project.artifactId}.jar"/>
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
This technique worked well for me:

I specially like the solution using maven-resources-plugin (see here) because is already included in maven, so no extra download is needed, and also is very configurable to do the copy at a specific phase of your project (see here to learn & understand about phases). And the best part of this approach is that it won't mess up any previous processes or build you had before :)
<project>
...
<build>
<plugins>
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>3.2.0</version>
<executions>
<execution>
<id>copy-resources</id>
<!-- here the phase you need -->
<phase>validate</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>/dir/where/you/want/to/put/jar</outputDirectory>
<resources>
<resource>
<directory>/dir/where/you/have/the/jar</directory>
<filtering>false</filtering>
<includes>
<include>file-you-want-to.jar</include>
<include>another-file-you-want-to.jar</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
...
</build>
...
</project>
Of course you can also use interpolated variables like ${baseDir} and other good stuff like that all over your XML. And you could use wild cards as they explain here
Maven dependency plugin is perfectly capable of copying all dependencies and just built artifact in a custom location. Following example will copy all runtime dependencies and a built artifact in a two execution phases.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.3.0</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<includeScope>runtime</includeScope>
<outputDirectory>${project.build.directory}/jars</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
<execution>
<id>copy-artifact</id>
<phase>package</phase>
<goals>
<goal>copy</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>${project.groupId}</groupId>
<artifactId>${project.artifactId}</artifactId>
<version>${project.version}</version>
<type>${project.packaging}</type>
</artifactItem>
</artifactItems>
<outputDirectory>${project.build.directory}/jars</outputDirectory>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
While documentation of dependency plugin states in its documentation that in order to copy built artifact you have to use any phase after the package phase, that is not true if you are building jars. In that situation you can use package phase. At least in 3.3.0 version of plugin.
