Maintaining the OSGi manifest manually sounds quite impractical to me though, so it's only half of the story. The other half is certainly BundlerEclipse, though it won't be good for us anyway. > *One possible way could be to do the following in Eclipse:* > *Maybe create a separate ant-target which you add to the builders in > eclipse.

Even right now, you expected to run `ant ide-dependencies`. That could be generalized to `ide-preparations` or somethingm which call ide-dependnecies and then also calls bnd to generates the metainf somewhere where Eclipse finds it but the Ant build ignores it. And then of course it has to be added to the gitignore. > I will try to investigate how I can modify the bnd ant-target so that the > MANIFEST.MF file is generated but not only in the JAR but also as a > separate file so that I do the copying. The important thing is that it must not affect the jar that Ant builds. That is, the metainfest generated by the Ant build must win. > If you have ideas or tips, let me know. > > > 2016-07-28 20:34 GMT+02:00 Daniel Dekany <[email protected]>: > >> Ah, I see... and I don't know the answer.
