Question

I use the assembly plugin to create several jars with some classes in it. I need custom names for the resulting jars: app_business.jar app_gui.jar core.jar etc.

Currently I have to following configuration:

    <plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
        <appendAssemblyId>false</appendAssemblyId>
    <finalName>app_business</finalName>
        <descriptors>
            <descriptor>assembly.xml</descriptor>
        </descriptors>
        <attach>true</attach>
    </configuration>
    <executions>
        <execution>
            <id>make-assembly</id>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
</plugin>

an the assembly.xml file:

    <assembly>
      <id>app_business</id>
      <formats>
        <format>jar</format>
      </formats>
      <baseDirectory>target</baseDirectory>
      <includeBaseDirectory>false</includeBaseDirectory>

      <fileSets>
        <fileSet>
          <directory>${project.build.outputDirectory}</directory>
          <outputDirectory></outputDirectory> 
          <includes>
            <include>org/xyz/**</include>
          </includes>
        </fileSet>    
      </fileSets>
    </assembly>

this creates a file app_business.jar which is perfect. But i have no idea how to create my other files. The option appendAssemblyId doesn’t help me, as it creates filenames in the format AppName-app_business.jar. I really need the exact filesname app_business.jar.

Any Idea? Thank you very much!

The standard maven plugins are meant for general, repetitive work. They gather all information from the POM and they are smart (in the sense that you don’t need to configure much).

If you need special tasks, then I suggest to use the ant plugin which allows you to embed a piece of Ant code in the POM. This allows you to run the jar task.
