Maven Tycho uses old JAR files

Discover how AppDynamics steps in to upgrade your performance game and prevent your enterprise from these top 10 Java performance problems, brought to you in partnership with AppDynamics.

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.
