During the development of SrcMixins4J I faced a strange problem with Tycho: I updated one of the libraries (srcmixins4j-core.jar) without incrementing the version number. I know this is not the standard “-SNAPSHOT” way, but I never had a problem with this before. Maven can handle such updates easily. Inside Eclipse everything was fine, but building with Maven outside Eclipse still referenced the old version and I got compile errors.

It took me some time to figure out that Tycho stores a second copy of the referenced JARs in the Maven repository. There is a folder named “p2/osgi/bundle”.

After deleting the “p2/osgi/bundle/org.fuin.srcmixins4j.core” folder, Tycho finally loaded the new version.
