How To

Build an internal repository containing the plugins from an Eclipse installation

Note: Running this command from a complete Callisto install can take some time (in the order of hours), thankfully it is a once off.

This will create pom's for all the plugins from your Eclipse installation located at
/path/to/eclipse/install and deploy them to your internal repository external_free

mvn eclipse:make-artifacts \
  -DeclipseDir=/path/to/eclipse/install \
  -DdeployTo=external_free::default::scp://NUCLEUS/usr/local/www/default/maven2_repositories/external_free

The created pom.xml will also have dependencies on any plugins they require.

Add the Eclipse RCP artifacts to your internal repository

This will add the Eclipse RCP artifacts which you have downloaded and install them into your internal repository external_free so they can be shared.

Upload the eclipse-RCP-3.2-win32.zip

mvn deploy:deploy-file \
  -DrepositoryId=external_free \
  -Durl=scp://NUCLEUS/usr/local/www/default/maven2_repositories/external_free \
  -DgeneratePom=true \
  -Dpackaging=zip \
  -DgroupId=org.eclipse \
  -DartifactId=eclipse-RCP \
  -Dversion=3.2 \
  -Dclassifier=win32 \
  -Dfile=eclipse-RCP-3.2-win32.zip

Upload the eclipse-RCP-3.2-delta-pack.zip

mvn deploy:deploy-file \
  -DrepositoryId=external_free \
  -Durl=scp://NUCLEUS/usr/local/www/default/maven2_repositories/external_free \
  -DgeneratePom=true \
  -Dpackaging=zip \
  -DgroupId=org.eclipse \
  -DartifactId=eclipse-RCP \
  -Dversion=3.2 \
  -Dclassifier=delta-pack \
  -Dfile=eclipse-RCP-3.2-delta-pack.zip

Create an Eclipse RCP Target

Follow the instructions below to configure your pom.xml. Then to create the Eclipse RCP target use mvn validate

Unpack the Eclipse RCP platform, delta pack and install any plugins that you need

  <build>
    <plugins>
      <plugin>
        <!-- Unpack the Eclipse RCP platform and delta pack -->
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <executions>
          <execution>
            <id>create-eclipse-target</id>
            <phase>validate</phase>
            <goals>
              <goal>unpack</goal>
            </goals>
            <configuration>
              <artifactItems>
                <artifactItem>
                  <groupId>org.eclipse</groupId>
                  <artifactId>eclipse-RCP</artifactId>
                  <version>3.2</version>
                  <classifier>win32</classifier>
                  <type>zip</type>
                </artifactItem>
                <artifactItem>
                  <groupId>org.eclipse</groupId>
                  <artifactId>eclipse-RCP</artifactId>
                  <version>3.2</version>
                  <classifier>delta-pack</classifier>
                  <type>zip</type>
                </artifactItem>
              </artifactItems>
              <outputDirectory>
                ${project.build.directory}
              </outputDirectory>
            </configuration>
          </execution>
        </executions>
      </plugin>
      <plugin>
      	<!-- Install all plugins that are dependencies of this pom -->
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-eclipse-plugin</artifactId>
        <version>2.3-INTERNAL-r489210</version>
        <executions>
          <execution>
            <id>install-plugins</id>
            <phase>validate</phase>
            <goals>
              <goal>install-plugins</goal>
            </goals>
            <configuration>
              <eclipseDir>target/eclipse</eclipseDir>
            </configuration>
          </execution>
        </executions>
      </plugin>

Define as dependencies any plugins needed in the target platform

Add each plugin needed to be in the target platform as a dependency in the pom.xml file.

For example, suppose that org.eclipse.update.core_3.2.0.v20060605.jar needs to be included, then:

  <dependencies>
    <dependency>
      <groupId>org.eclipse.update</groupId>
      <artifactId>org.eclipse.update.core</artifactId>
      <version>3.2.0</version>
    </dependency>
  </dependencies>

This will also download all transitive dependent plugins.

Build your Eclipse Plugin

As far as I know the maven-eclipse-plugin can't help you to build your Eclipse plugin.

There is some work going on with OSGi bundles being built, some discussions with the Eclipse team to expose and unify classpath and PDE features to make it easier to externally tool plugin development.

However you can use the pde-maven-plugin@codehaus to build your plugins with Maven. pde-maven-plugin invokes the Ant pde build files to actually do the work. You can even create an RCP application this way.
