We are building a jar file from external(to the project) classes.
That works fine but we have not been able to figure out how to also include the external source files. I have tried using the "< includes >" tag but only end up with a manifest file in the final jar when used. I have looked at using the maven-resources-plugin but either I used it wrong or it doesn't work in my case. Here is a copy of our of code:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<!-- <phase>generate-resources</phase> -->
<phase>clean</phase>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<classesDirectory>${itendant.path}/web/rocket/WEB-INF/classes</classesDirectory>
<finalName>${itendant.jar.name}</finalName>
<outputDirectory>${itendant.jar.path}</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
Sources? Do you mean external dependencies? These should also be managed with maven, using mvn deploy:deploy-file as described on http://maven.apache.org/plugins/maven-deploy-plugin/usage.html , and imported in your pom.xml.
If you really mean external resources, then a proper resources declaration would be:
<project>
...
<build>
...
<resources>
<resource>
<directory> [your folder here] </directory>
</resource>
</resources>
...
</build>
...
</project>
You can have multiple tags if you have multiple resource directories, of course. Also note that building anything during clean is questionable, as clean is not run every build - package would be a better option.

I have an antrun task (goal run on phase prepare-package) set up that creates a file and saves it in /target/foo.bar. How do I add that to the artifact that gets created by maven (depending on module, it could be a jar or a war file)?
I have tried it with resources, with the builder-helper plugin, and the jar plugin - no luck:
<resources>
<resource>
<directory>target</directory>
<includes>
<include>**/foo.bar</include>
</includes>
</resource>
</resources>
That doesn't seem to do anything.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<id>attach-artifacts</id>
<phase>package</phase>
<goals>
<goal>attach-artifact</goal>
</goals>
<configuration>
<artifacts>
<artifact>
<file>${project.build.directory}/foo.bar</file>
<type>bar</type>
</artifact>
</artifacts>
</configuration>
</execution>
</executions>
</plugin>
According to debug output, this seems to install something extra in the repo, but doesn't add foo.bar to the artefact.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.0.2</version>
<configuration>
<includes>
<include>../foo.bar</include>
</includes>
</configuration>
</plugin>
No observable effect, either. :(
(I assume this might work for the war file, but I'd prefer one way to do it for both artifact types, if possible - plus I really need this to work for the jars, too...)
Is there a way to do what I want to do?
(I'd prefer not saving my file in src/main/resources first; I thought the packaging processes would pick files up from the build directory after they were placed there anyway, but I suppose I misunderstood something...)
I had my file saved to project.build.directory. Changing that to project.build.outputDirectory means the jar plugin is picking it up, without the need of any other plugins. Unfortunately, that doesn't sort the war issue out... :(
I had a similar problem and stored the resulting artifact in
target/${project.name}-${project.version}/foo.war
To be more precise, I created the war from a directory using the ant target
<war warfile="target/${project.name}-${project.version}/foo.war" basedir="somedir" />
Then it was correctly added to the surrounding ear.
I have a problem while processing .xsd file during my maven build.
I use jaxb2 plugin but I have to download external dependiencies from my .xsd files. The problem is that these dependencies (.xsd) are from enviroment which is unstable and very often my build fails because maven cannot download xsd file. How to configure jaxb plugin to force him to try download xsd few times to prevent build failure?

Author of the maven-jaxb2-plugin here.
You have two parts here: managing the downloads of external resources and compiling the schemas, rewriting "external" links to local files.
The first (managing downloads) is not in the scope of the maven-jaxb2-plugin, the second is supported with
catalogs.
In short, you can create a catalog file like this:
REWRITE_SYSTEM "http://www.w3.org" "w3c"
Or this:
REWRITE_SYSTEM "http://schemas.opengis.net" "maven:org.jvnet.ogc:ogc-schemas:jar::!/ogc"
And use this file to "rewrite" absolute links to local files or resources within Maven artifacts:
<configuration>
<catalog>src/main/resources/catalog.cat</catalog>
</configuration>
As for the first part, I don't think managing downloads with retries, continuations and all other stuff should be in the scope of the JAXB2 Maven plugin.
ps. You don't need build-helper-maven-plugin/add-source with maven-jaxb2-plugin, source directory is added automatically.
Apparently the maven-jaxb2-plugin does not support such a feature. (And neither does the maven-download-plugin nor even the maven-dependency-plugin).
Three solutions come into my mind at the moment (plus two and a half inspired by LIttle Ancient Forest Kami's comment) [Numbers reflect the precedence of what I would do]:
Use a CI tool (Jenkins, etc.) that supports retry on job failure. [1]
Handmade:
Use the GMavenPlus plugin with a script ... [2]
Use the Maven AntRun plugin with a script ... [3]
Use the Exec Maven plugin with a program ... [5]
... that performs the download and retry and bind it to the generate-resources phase in your project's POM.
Create a Maven plugin with appropriate parameters (url, outputDirectory, retryCount) that uses the maven-download-plugin and performs the retry. Bind its goal to the generate-resources phase in your project's POM. [4]
Create a check-download Maven project that uses the maven-download-plugin bound to the generate-resources phase to download the .xsd. [6]
Create a shell script that contains the following (in pseudo code):
download:
counter++
<check-download project>/mvn generate-resources
if error and counter < maxRetryCount goto download
if not error
<your project>/mvn ...
else
display appropriate error message
There is also a question Maven download retry? from 2005. Unanswered.
I'm using mvn compile to compile my Maven webapp. This project has a resources folder instead of the java folder created for a .jar project. My problem is that mvn finds no sources, and I haven't find a way in the maven docs to proceed this way. Is there a way, either by mvn command options or by pom.xml modification to make mav aware of the resources folder and compile it?
I know changing the name from resources to java makes the deal, but that's a spureous way to proceed.
To include additional source directories in your project you can use the Build Helper Maven Plugin
So for example the following configuration will add the src/main/resources folder of your project as a source folder.
<project>
...
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>1.8</version>
<executions>
<execution>
<id>add-source</id>
<phase>generate-sources</phase>
<goals>
<goal>add-source</goal>
</goals>
<configuration>
<sources>
<source>${basedir}/src/main/resource</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
Look at your .classpath file. That should have what folders including src and test are added. You can then add additional resources. I would normally use the IDE to look at the build path and add/exclude resources.
I have a multi-module maven project like this:
-project
+-sub-project1
+-sub-project2
For my JUnit tests, I create another persistence.xml file inside the sub-project1/src/test/resources/META-INF. This project is a dependency for the sub-project2, in this way, I was hopping that the tests of sub-project2 use the same test persistence.xml from sub-project1, but it not happen.
So, I was wondering why I can made maven automatically copy this file to the other submodules during the test phase... maybe it's better if I put this file in the project/resources folder, e.g., and then copy them...
I was hopping that someone already managed this to work somehow, and can help me or show how to do this.
Thanks in advance.
I managed it to work like this:
I create a project/assembly/test/resources/META-INF/persistence.xml file, and add this to my pom.xml:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<executions>
<execution>
<id>copy-test-persistence-xml-resources</id>
<phase>process-test-sources</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>src/</outputDirectory>
<resources>
<resource>
<directory>${project.parent.basedir}/assembly/</directory>
<filtering>true</filtering>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
It works gracefullt.
I have some java source files that use a package prefix (they are emulating some JDK classes). I use these files with the prefix to run against some unit tests. If the tests pass I want to produce a jar that contains the source files but with the package prefix removed from all the java files.
I am using maven for builds. Does any one know of a way to do this? Essentially what I want is something like the resources plugin filtering feature, but that does proper search and replace (like: s/my.package.prefix.//g), rather than filtering on ${vars}.
You can also use
http://code.google.com/p/maven-replacer-plugin/
100% maven and doing exactly what you want and more
This can be solved with the antrun plugin. Firstly the sources need to be copied to the target directory, with:
<build>
...
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.java</include>
</includes>
</resource>
</resources>
...
</build>
Secondly you use the replace task of the antrun plugin to replace the files using the prepare package phase
<build>
...
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>prepare-package</phase>
<configuration>
<tasks>
<replace token= "my.package.prefix." value="" dir="target/classes">
<include name="**/*.java"/>
</replace>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
...
</build>
This will copy the source files to target/classes in the process-resources phase, do a search and replace on the files inplace in the target/classes directory in the prepare-package phase and finally they will jarred up in the package phase.
