Execution point between prepare-package and package in Maven build-process

Question

The package phase of a project with packaging war, prepares an exploded-war in the target folder and packages this into the final war-file.

Is it possible to make some changes, editing files, removing files and so on, between prepare-package and package phases? I'm searching for an extension point (Maven execution-phase) where the resources are already copied and in the exploded-war structure.

1. [maven phase] Copy resources and explode to target/{finalName}.
2. [custom] Do some complex custom changes (e.g. implemented with maven-antrun).
3. [maven phase] Package the changed stuff into the final war.

I thought this could be possible between the phases prepare-package and package. Unfortunately after the prepare-package no exploded war is available to be changed and packaged later.

Can you give me a hint how to achieve this? Thank you very much.

Answer 1

This configuration calls the exploded goal in the prepare-package phase. This gives you the chance to work on the exploded war directory in subsequent plugin definitions e.g. maven-antrun.

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-war-plugin</artifactId>
   <version>2.1.1</version>
   <executions>
     <execution>
       <id>prepare-war</id>
       <phase>prepare-package</phase>
       <goals>
         <goal>exploded</goal>
       </goals>
     </execution>
   </executions>
</plugin>
