Java Model Exception: Java Model Status [Cannot nest importing a gradle project working on IntelliJ Idea #987

Open aleroot opened 4 years ago

This morning I've tried to load a multi module gradle project perfectly working on IntelliJ Idea 2020.1 with the gradle setting: "Generate IntelliJ IDEA module per gradle source set" unticked, and this is the error I get:

Java Model Exception: Java Model Status [Cannot nest 'ExternalServicesTests/src/test/java' inside 'ExternalServicesTests/src/test'. To enable the nesting exclude 'java/' from 'ExternalServicesTests/src/test']

Is there a .classpath file already present in the project when you imported it? Removing it should resolve issue.

If that's not the case, I'd need a minimal example project to investigate further.
