I have a problem in Eclipse 2019-09 after I migrated from WebSphere Application Server to Open Liberty server and switched from Jdk8 to Jdk11. Building the workspace is getting stuck forever. It works one time and then when I restart Eclipse, the problem of building the projects gets stuck forever and I have to terminate Eclipse and delete the .metadata folder for the workspace to be fixed.
For info, my workspace contains 29 java projects (web applications) and I'm using Maven to build it.
I also have tried to disable the validations, increased Eclipse's memory, deleted the indexes and history and disable building automatically.
Can someone help on that matter please?
Thank you in advance
