The Tycho project provides additional tools that may be useful when working with Tycho.

tycho-p2-extras-plugin

The mirror goal of the tycho-p2-extras-plugin copies installable units (plus their corresponding artifacts) from one or more p2 repositories into the build directory. This goal is available since version 0.13.0.

Example usage:

Mirror the org.eclipse.rcp feature from the Indigo p2 repository to target/repository. Filter the platform-specific fragments to only include linux/gtk/x86_64 os/ws/arch.

</build>

The mojo has almost the same parameters as the p2.mirror ant task

tycho-eclipserun-plugin

This plugin allows to run an Eclipse application from Maven. This plugin is available since version 0.14.0. One use of this plugin is building the documentation index using Eclipse's antRunner and the help.buildHelpIndex Ant task.

Without Tycho, this would typically be done by having an Ant file with the help.buildHelpIndex task. For example, in customBuildCallbacks.xml:

<project name="Build specific targets and properties" default="noDefault">
    <target name="post.build.jars">
        <antcall target="build.index"/>
    </target>
 
    <target name="build.index" description="Builds search index for the plug-in: org.eclipse.someplugin.doc.user." if="eclipse.running">
        <help.buildHelpIndex manifest="plugin.xml" destination="."/>
    </target>
</project>

tycho-eclipserun-plugin can be used to run Eclipse's antRunner and reuse that Ant file.

org.eclipse.someplugin.doc.user/pom.xml:

<build>
    <plugins>
        ...
        <plugin>
            <groupId>org.eclipse.tycho.extras</groupId>
            <artifactId>tycho-eclipserun-plugin</artifactId>
            <version>${tycho-version}</version>
            <configuration>
                <appArgLine>-application org.eclipse.ant.core.antRunner -buildfile customBuildCallbacks.xml build.index</appArgLine>
                <dependencies>

                    </dependency>
                    <dependency>
                        <artifactId>org.eclipse.help.base</artifactId>
                        <type>eclipse-plugin</type>
                    </dependency>
                </dependencies>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>eclipse-run</goal>
                    </goals>
                    <phase>compile</phase>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

For other scenarios, it might be necessary to change the elements in <dependencies>. Also, note that the JVM arguments can be changed with the <argLine> paremeter. A version of the plugin compatible with Tycho 0.13 is available at Eclipse Labs.


For example if you would like to install eclipse using this plugin you could try something like:

<properties>
    <tycho-extras-version>0.14.0</tycho-extras-version>
    <tycho-version>0.14.1</tycho-version>
    <features>org.eclipse.sdk.ide,org.eclipse.platform,org.eclipse.jdt,org.eclipse.m2e.feature.feature.group,org.eclipse.m2e.logback.feature.feature.group
