I just asked a friend who is a Eclipse contributor and very familiar with OSGI practises. Here is a rough translation of his anwer:
*bndtools takes the "generate Manifest" approach. * *Eclipse on the other hand takes "Manifest first" approach. * *You cannot mix the two, because Eclipse needs the manifest file, bndtools doesn't. * *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. This ant target could copy the generated MANIFEST.MF file into the Eclipse Workspace project under META-INF/MANIFEST.MF instead of putting it only in the jar file. * 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. If you have ideas or tips, let me know. 2016-07-28 20:34 GMT+02:00 Daniel Dekany <ddek...@freemail.hu>: > Ah, I see... and I don't know the answer.
