    TFS plugin does not work on the latest MyEclipse 2018 CI update (April 3, 2019). We had to uninstall MyEclipse and reinstall an older version without the latest update. Please look into this.

    This looks like the issue you are running into:

    There is a workaround provided for running on Java 11. It looks like the issue is not due to the MyEclipse upgrade itself other than the Java runtime:

    Just checking in to see if you were able to implement the workaround suggested by Tim – with both Java 11 and 12 out, it’s odd that there’s hasn’t been a more recent release of the plugin from Microsoft to fix this issue.

    An alternative fix would be to modify MyEclipse to start with Java 10, by editing the myeclipse.ini file and modifying the -vm argument to point to a Java 10 executable, as described here. Hope this helps – do let us know if you need further assistance.

    Sorry to be late to the party, but I’m experiencing the exact same issue on JDK 1.8.0_181. I have uninstalled and reinstalled the TFS Plugin, including a restart if the machine in between, all to no avail. This started immediately after I upgraded to CI 2019.4.0, build 16.0.0-20190403. So if this is, as you say, an issue with Java 11 and 12, why is it happening on Java 8?

    Never mind. I didn’t realize that ME bundled in a JRE 11 Runtime. I simply re-pointed the ,ini file to the 1.8.0_181 JRE and all is working again. Maybe. I need to see if my projects are going to reconnect to my TFS Repos.
