After such a long period of inactivity, the Eclipse version of the jenkins plugin will be paused. There are some reasons. We agreed it was too ambitious to develop both versions in parallel whereas the intellij version is still immature and requires a lot of enhancements.
It does not mean we give up this "fork". We just want to focus our efforts on what works at now (the current code for Eclipse does not do anything).
We are sure you understand this situation and we apologize people who are waiting for the Eclipse version.
