[provide a description of the issue]

Environment

• Operating System: manjaor Linux, macOS
• JDK version: Oracle JDK 8u202 and 11.0.11
• Visual Studio Code version: 1.58.1 (Universal) Commit: 2aeda6b18e13c4f4f9edf6667158a6b8d408874b
• Java extension version: v0.80.0

Steps To Reproduce

giving a multi maven project:

├── projectA │   ├── pom.xml │   ├── A.java ├── projectB │   ├── pom.xml │   ├── B.java ├── pom.xml

in A.java, I cannot navigate into B.java, which is MPPQueueInfo.java below

However, the project can build and run successfully. In another single maven project, nothing like this occurs.

[arjenzhou]

the project is a multi maven project. two sub-modules appear like this, others do not

[snjeza]

@arjenzhou could you attach your .project, .classpath files?

[arjenzhou]

@snjeza ok, files here. https://gist.github.com/arjenzhou/58da6baa213be889201b4d28260610f3

[arjenzhou]

another message may help is that the project is using Java 8, settings.json here

@arjenzhou could you move your java files to the <your_project>/src/main/java directory?
