I cloned the Graph Data Science source code (https://github.com/neo4j/graph-data-science), checked out branch 1.2 (compatible with Neo4j 4.0.4), opened it within Intellij IDEA. It seems the IDE can't recognize the outer-most folder "graph-data-science" as a project folder. As showed in the picture below, Intellij can't "go to declaration":
I can build the library ("./gradlew packaging:shadowJar") successfully with Command Line. The JDK for Intellij is Oracle JDK 11.0.7 x64.
Any help is really appreciated. I'm more familiar with Python & PyCharm. But not very proficient at programming with Java.
