Maven - How to override version? - maven

my pom.xml looks like this:
<project>
...
<version>1.0.0-A</version>
...
</project>
I have to get rid of the '-A' suffix. So I found this plugin which removes it and saves it into a new variable.
<plugin>
<groupId>org.codehaus.groovy.maven</groupId>
<artifactId>gmaven-plugin</artifactId>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>execute</goal>
</goals>
<configuration>
<source>
System.setProperty("versionWithOutPrefix", "${project.version}".replace('-SNAPSHOT', ''))
</source>
</configuration>
</execution>
</executions>
</plugin>
But I need to get the value of <version> changed. Is there a way to do this?

How to remove a a specific directory from the Maven's target directory at the end of the build?

I have a task to unpack all the jars mentioned in the pom.xml and then jar the unpacked content into one single jar. I am able to do this using the unpack-dependency goal of the dependency plugin and the jar plugin.
However, after i generate the new jar, I want to delete the folder that was created after unpacking. I am using the following code snippet in my pom.xml(Please read the comments above each plugin).
<build>
<plugins>
<!-- This part of the code is used to unpack all the dependencies mentioned in my pom.xml -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.10</version>
<executions>
<execution>
<id>unpack-dependencies</id>
<phase>package</phase>
<goals>
<goal>unpack-dependencies</goal>
</goals>
<configuration>
<includes>**/*.class</includes>
<outputDirectory>${project.build.directory}/alternateLocation</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>true</overWriteSnapshots>
</configuration>
</execution>
</executions>
</plugin>
<!-- This part of the code is used for creating a jar with all the contents of the "alternateLocation" directory above -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<classesDirectory>${project.build.directory}/alternateLocation</classesDirectory>
<outputDirectory>${project.build.directory}</outputDirectory>
<finalName>abc</finalName>
</configuration>
</execution>
</executions>
</plugin>
<!-- I am using this part of the code to delete the "alternateLocation" after everything is done, but it deletes the target directory instead -->
<plugin>
<artifactId>maven-clean-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<id>auto-clean</id>
<phase>install</phase>
<goals>
<goal>clean</goal>
</goals>
<configuration>
<filesets>
<fileset>
<directory>${project.build.directory}/alternateLocation</directory>
</fileset>
</filesets>
<excludeDefaultDirectories>${project.build.directory}</excludeDefaultDirectories>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
The clean plugin is basically deleting the target directory by default.
So how can I delete the "alternateLocation" folder from the target directory at the end of the build. (I guess you can do it using the maven-antrun-plugin but i don't want to use this plugin.).
You can solved this by using the maven-assembly-plugin via the predefined descriptor jar-with-dependencies which can be done by the following:
<project>
[...]
<build>
[...]
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.6</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
[...]
</project>
Than you don't need supplemental configuration.

Multiple XSD schemas for castor with castor-maven-plugin

Is it possible to work with multiple xsd schemas with castor-maven-plugin simultaneously?
I use it in rotation (schema1 and schema2) in POM and it works:
<build>
...
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>castor-maven-plugin</artifactId>
<version>2.1</version>
<configuration>
<schema>src/main/castor/schema1.xsd</schema>
<dest>src/main/java</dest>
<packaging>com.path.to.schema1.beans</packaging>
</configuration>
<executions>
<execution>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
</plugin>
...
with a little problem: mvn:install collects all classes to target except chema2.crd (or schema1 if I use schema2). I have to copy file manually.
Can I fix it? Are there any ways to configure castor-maven-plugin ?
Try using multiple executions like this:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>castor-maven-plugin</artifactId>
<version>2.1</version>
<executions>
<execution>
<id>firstSchema</id>
<goals>
<goal>generate</goal>
</goals>
<configuration>
<schema>src/main/castor/schema1.xsd</schema>
<dest>src/main/java</dest>
<packaging>com.path.to.schema1.beans</packaging>
</configuration>
</execution>
<execution>
<id>secondSchema</id>
<goals>
<goal>generate</goal>
</goals>
<configuration>
<schema>src/main/castor/schema2.xsd</schema>
<dest>src/main/java</dest>
<packaging>com.path.to.schema2.beans</packaging>
</configuration>
</execution>
</executions>
</plugin>

Maven rename a file after everything else finishes

I have a project which I need to rename the final output file generated by the Maven Assembly Plugin after everything else finishes (in the compiling/building/assembly process).
The Maven Assembly Plugin is generating a final .zip file, based on the project's name, and I need to rename this completely to final-version.oxt. I'm trying to use the maven-antrun-plugin to rename it, as pointed by other similar questions here, but no luck (I've never used Maven or Ant before, so maybe I'm missing something).
This is the <build> section of the project's pom.xml. The rename part seems to be completely ignored, since no file is generated in my home folder.
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<id>assembly</id>
<phase>package</phase>
<goals>
<goal>attached</goal>
</goals>
<configuration>
<archive>
<manifestFile>src/main/resources/META-INF/MANIFEST.MF</manifestFile>
</archive>
<descriptors>
<descriptor>src/main/assembly/ooo-jar.xml</descriptor>
<descriptor>src/main/assembly/ooo.xml</descriptor>
</descriptors>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>deploy</phase>
<configuration>
<tasks>
<copy file="${project.build.directory}/target/libreofficeplugin-ooo.zip"
tofile="/home/brunofinger/final-version.oxt" />
</tasks>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
A few modifications made it work, probably the phase was wrong, but using <phase>install</phase> seems to make it work:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<phase>install</phase>
<configuration>
<target>
<copy file="${project.build.directory}/libreofficeplugin-ooo.zip" tofile="${project.build.directory}/final-version.oxt" />
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
This question is nearly an year old, but in case anyone else is facing similar issue, here is an alternate solution.
If you are looking for a more mavenish way of doing it,you can use
<plugin>
<groupId>com.coderplus.maven.plugins</groupId>
<artifactId>copy-rename-maven-plugin</artifactId>
<version>1.0.1</version>
<executions>
<execution>
<id>rename-file</id>
<phase>install</phase>
<goals>
<goal>rename</goal>
</goals>
<configuration>
<sourceFile>${project.build.outputDirectory}/libreofficeplugin-ooo.zip</sourceFile>
<destinationFile>${project.build.outputDirectory}/final-version.oxt</destinationFile>
</configuration>
</execution>
</executions>
</plugin>
and in case you want to copy instead of rename, use the copy goal instead of the rename goal.
You don't need to use antrun to rename the output file. Just use the tag finalName of the assembly plugin to rename the output file.
<?xml version="1.0" encoding="UTF-8"?>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<id>assembly</id>
<phase>package</phase>
<goals>
<goal>attached</goal>
</goals>
<configuration>
<archive>
<manifestFile>src/main/resources/META-INF/MANIFEST.MF</manifestFile>
</archive>
<descriptors>
<descriptor>src/main/assembly/ooo-jar.xml</descriptor>
<descriptor>src/main/assembly/ooo.xml</descriptor>
</descriptors>
<finalName>final-version.oxt</finalName>
</configuration>
</execution>
</executions>
</plugin>

How can I combine jars using Maven?

The following snippet creates 2 JARS:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<id>build-dependency</id>
<phase>compile</phase>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<classifier>dependency</classifier>
<classesDirectory>${project.build.directory}\dependency</classesDirectory>
<includes>
<include>${dependancyInclude}</include>
</includes>
</configuration>
</execution>
<execution>
<phase>compile</phase>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<classifier>module</classifier>
<classesDirectory>${project.build.directory}\classes</classesDirectory>
</configuration>
</execution>
</executions>
</plugin>
I would like to combine these two JARs into one using the assembly plugin, currently I have the following:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2</version>
<executions>
<!-- Combine all the JARs in the /target folder into one JAR -->
<execution>
<id>make-assembly</id>
<phase>compile</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<attach>true</attach>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<finalName>${project.artifactId}-${project.version}</finalName>
<appendAssemblyId>true</appendAssemblyId>
</configuration>
</execution>
</executions>
</plugin>
Currently only one of the two JARS in included in the final JAR that is created by the assembly plugin.
If I understand you correctly, you actually want to merge the jar files into one big jar file. This can be achieved using the maven-shade-plugin (instead of the maven-assembly-plugin).
For example:
<project>
...
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.0</version>
<configuration>
<!-- Put your configuration here, if you need any extra settings.
(You should be okay with the defaults). -->
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
...
</project>

Property autocapitalization in maven

I have a maven project that requires a property to be set at the command line(-Dmy.property=val).
What I need to do is to convert that string into all caps since that property is
used for string replacement in a number of files through the maven-resources-plugin.
What's the simplest way to do this?
The groovy plugin could be used. The following configures it to run at the beginning of the Maven build process:
<plugin>
<groupId>org.codehaus.groovy.maven</groupId>
<artifactId>gmaven-plugin</artifactId>
<version>1.0</version>
<executions>
<execution>
<phase>initialize</phase>
<goals>
<goal>execute</goal>
</goals>
<configuration>
<source>
import org.apache.commons.lang.StringUtils
project.properties["my.property"] = StringUtils.upperCase(project.properties["my.property"])
</source>
</configuration>
</execution>
</executions>
</plugin>
With following code, MY_PROPERTIES equals to uppercased value of my.properties:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>1.12</version>
<executions>
<execution>
<id>properties-to-uppercase</id>
<goals>
<goal>regex-property</goal>
</goals>
<configuration>
<name>MY_PROPERTY</name>
<regex>.*</regex>
<value>${my.property}</value>
<replacement>$0</replacement>
<failIfNoMatch>false</failIfNoMatch>
<toUpperCase>true</toUpperCase>
</configuration>
</execution>
</executions>
</plugin>
