Re: [tycho-user] Building a documentation index with Tycho
|
the building blocks for creating a mojo which calls a (forked) eclipse application should already be there (P2ApplicationLauncher).
For example see
https://github.com/sonatype/tycho-extras/blob/master/tycho-p2-extras-plugin/src/main/java/org/eclipse/tycho/plugins/p2/extras/PublishFeaturesAndBundlesMojo.java
Extending the OSGi runtime with additonal bundles should also be possible be registering a plexus component implementing
http://git.eclipse.org/c/tycho/org.eclipse.tycho.git/tree/tycho-p2/tycho-p2-facade/src/main/java/org/eclipse/tycho/p2/facade/internal/TychoP2RuntimeMetadata.java

Subject: Re: [tycho-user] Building a documentation index with Tycho
Hi Igor,
Thank you for the quick response. Yes I was able to make it work. It
works either by making the plugin part of Tycho (using tycho group id
and parent) or as a "separate/external" plugin. It's basically a
stripped down version of the TestMojo class and the code is quite
simple. So, making this kind of extension seems easy enough to me. The
hardest part really was to learn about Maven, Tycho, PDE Build and the
Equinox Launcher all at the same time.
I think providing a generic mojo to execute eclipse applications would
great! But one problem I see with this approach is that the user would
have to manually configure the dependencies of the application. For
example, antRunner needs org.apache.ant and org.eclipse.help.base so the
user would have to configure the plugin in the POM in a way to include
the dependencies. The user would just "have to know" which bundles are
needed for each Eclipse application. That or the mojo could just add
everything in p2/bundles... but I'm not sure how efficient that would
be. So the way I see it, making a generic mojo will certainly allow
other use cases (applications) in the future but it also puts more
burden on the configuration the user has to do. Having a very specific
mojo to build a documentation index makes it very easy to use since it
can make some assumptions for the user, for example it can have the ant
dependencies hard-coded inside the mojo. Also, with the specific mojo,
we could get rid of the user-provided ant build file
(customBuildCallbacks.xml) and move the two simple parameters (manifest
and destination) to the plugin configuration then create the ant file on
the fly. So I guess this is about great flexibility versus ease of use.
I'd like to hear your thoughts on that before creating a bugzilla and
contributing code.
Regards,
Marc-Andre
