Question

We use Hudson, Maven2 and maven-ear-plugin.

Is it possible to have the built EAR files to contain SVN revision in their filename (something like project-1234.ear)?

Answer 1

You can use the buildnumber-maven-number for this. Basically, this plugin sets a ${buildNumber} property that you can use later in the maven ear plugin configuration.

First, setup the Build Number Maven Plugin as documented here:

<plugins>
  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>buildnumber-maven-plugin</artifactId>
    <version>1.0-beta-4</version>
    <executions>
      <execution>
        <phase>validate</phase>
        <goals>
          <goal>create</goal>
        </goals>
      </execution>
    </executions>
    <configuration>
      <doCheck>true</doCheck>
      <doUpdate>true</doUpdate>
    </configuration>
  </plugin>
  ...
</plugins>

Then, use the finalName parameter to customize the name of the generated ear. For example:

<plugins>
  ...
  <plugin>
    <artifactId>maven-ear-plugin</artifactId>
    <version>2.4</version>
    <configuration>
      <finalName>${project.artifactId}-r${buildNumber}</finalName> 
      ...
    </configuration>
  </plugin>
  ...
</plugins>
