I am on ubuntu 18.04 and fairly new on IntelliJ. IntelliJ keeps on failing to build/run my project and shows the following error:

Error:Internal error: (java.util.concurrent.ExecutionException) java.lang.IllegalArgumentException: Argument for @NotNull parameter 'url' of org/jetbrains/jps/model/impl/JpsUrlListImpl.addUrl must not be null

It starts working once run the command

rm -rf ~/.IdeaIC2018.3

which deletes the caching but it is very inefficient to do this every time before I want to run my project.
