Mac OSX 10.14.6 Mojave IntelliJ IDEA ULTIMATE 201903 Multi-module project
Whether I updated IntelliJ or activated it, suddenly there was a phenomenon that I could not connect due to a network error.
Restart your mac I was able to resolve this symptom by rebooting twice for some reason. So it is unclear if it can be solved in one shot.
ClassNotFoundException: compile error with JAXBException
Since JAXBException disappears from Java9 when java9 or later is set as sdk I get a compile error.
If the above doesn't work, try the following and it works
.gradlefolder and the
buildfolder of each module
I hope it helps someone.
