View source for Tycho/Additional Tools

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

=tycho-p2-extras-plugin=

== <tt>mirror</tt> goal ==

The <tt>mirror</tt> goal of the <tt>tycho-p2-extras-plugin</tt> copies installable units (plus their corresponding artifacts) from one or more p2 repositories to a p2 repository in the file system. The goal has almost the same parameters as the [http://help.eclipse.org/helios/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Fguide%2Fp2_repositorytasks.htm p2.mirror ant task].

Also see the [http://eclipse.org/tycho/sitedocs-extras/tycho-p2-extras-plugin/mirror-mojo.html p2 mirror goal reference documentation] .

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.

== <tt>publish-features-and-bundles</tt> goal ==

The <tt>publish-features-and-bundles</tt> goal of the <tt>tycho-p2-extras-plugin</tt> can be used to add p2 metadata to features and bundles built with other, non-p2-enabled build systems, so that the artifacts can be used in a Tycho build.

Example usage: Generate full p2 metadata for artifacts from an old-style update site.

=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:

<source lang="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>
</source>

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

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

<source lang="xml">
<build>
    <plugins>
        ...
        <plugin>
            <groupId>org.eclipse.tycho.extras</groupId>

            <version>${tycho-version}</version>

            </executions>
        </plugin>
    </plugins>
</build>
</source>

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 [http://code.google.com/a/eclipselabs.org/p/tycho-eclipserun-plugin/ Eclipse Labs].
