[sapphire-dev] Sapphire + tycho build support

[Greg Amerson <gregory.amerson@xxxxxxxxxxx>]

Hello everyone,

This is just a FYI for any users that are trying to use tycho to build their eclipse plugins that use sapphire.  Below is how I setup the customBuildCallbacks.xml so the annotations processor and sapphire ant tasks would run at the right point during the build.

Here is what I did.  In the pom.xml for any plugin that has sapphire generated models I modified the pom to fire off a ant script during the generate-sources phase and then had to modify the callback ant script to reference maven/tycho provided classpath references.  

1) In your pom.xml used snippet [1] to launch the ant script during generate-sources

2) In customBuildCallback.xml, had to make the following changes:

2a) modify the location of ant-contrib.jar for my build environment

2b) Change the <safe-apt /> task [2] to reference classpath refs provided by maven3/tycho

2c) Change the <taskdef /> element [3] for how to find the sapphire SDK ant task

3) In my plugin.xml I had to explicitly depend on these bundles [4], so that when maven/tycho generates the classpath references it will include those two jars on the classpath.  There may be a more elegant way to do encode this dependnecy in maven/pom.xml but I am not a maven expert but doing this worked.

Hope this can be of help to other sapphire+tycho users.  Konstantin, is there a wiki for sapphire project that I could add this to?
