Can't create a new Gradle project in Intellij Ultimate Edition 2017

Question

While starting a new Gradle based java project, i get

Error:The modules ['helloworld', 'helloworld-app_test', 'helloworld_main'] point to same directory in the file system. Each module has to have a unique path.

What's causing this ? How can it be solved?

Answer 1

I encounter it in IDEA2017.2.3. AS this post : https://github.com/square/assertj-android/issues/174

I delete .idea directory then refresh Rebuild project. After rebuild project, IDEA will recreate .idea directory and *iml files.

It work for me.

Answer 2

This usually is the result of old iml files. Delete all .iml files and re import them using Android Studio. That worked for me.. https://developer.android.com/studio/intro/migrate.html
