Re: [tycho-dev] m2e workspace resolution for Tycho plugins

[Igor Fedorenko <igor@xxxxxxxxxxxxxx>]

If you install [3], source lookup works now too . Now I can debug
through maven, tycho and eclipse code without having to do any manual
mvn install or source lookup configuration. I like it. :-)

There is one notable exception to automatic source code lookup, however.
You still need to configure source path lookup manually for equinox
itself, jdt.core and jdt.apt. These artifacts are resolved from Maven
repositories but do not have embedded maven metadata, i.e.
META-INF/maven/ folder. I don't feel like solving this problem now.

Next up is run/debug 'as tycho integration test'. I want to be able to
make changes to Tycho sources or sources of any of Tycho dependencies
and run/debug all or some of Tycho ITs right from my m2e workspace.
Debugging will likely be tricky because there will be two JVMs involved,
one that runs IT and one that runs Maven build. Not sure if I'll try to
use single JVM for both or if I'll try to make JDT debugger work with
multiple JVMs associated with one launch. Both approaches look tricky.
