Re: [tycho-user] Advice: OSGi'fy jars into target platform or Classpath

[Igor Fedorenko <igor@xxxxxxxxxxxxxx>]

I use maven-bundle-plugin Embed-Dependency feature [1] to "wrap"
thirdpary dependencies in OSGi bundles and pomDependencies=consider [2]
Tycho target platform configuration parameter to use these wrapper
bundles from Tycho builds. See m2e embedded maven runtime, for example [3].

The only real caveat here is that wrapper bundles must be built
separately, before building any tycho project that uses them.
