Vscode-java: Extension causes `bad class file` and `ClassNotFoundException` in Maven build

[vojtechhabarta]

I have a Maven project with submodules. When I open it in VS Code with this extension installed everything seems to work perfectly (code completion, javadoc, go to definition...). But when I run mvn clean install externally extension starts throwing tens of BadLocationExceptions (displayed in Output tab).

Moreover maven build fails! I can see some bad class file errors from maven-compiler-plugin and bellow TypeNotPresentException caused by ClassNotFoundException from some test run by maven-surefire-plugin. When I close VS Code Maven build works.

Environment

• Operating System: Window 10
• JDK version: 1.8.0_112
• Visual Studio Code version: 1.17.0
• Java extension version: 0.11.0

Steps To Reproduce

1. clone https://github.com/vojtechhabarta/typescript-generator.git
2. open folder in VS Code
3. check that it works
4. run mvn clean install
5. build fails with TypeNotPresentException in tests

Maven clean build wreaking havoc is reported in #314.
The Maven build itself failing? That's a new one. Not sure we can fix that part.

[fbricon]

I suggest you run mvn install (without the clean part), if it doesn't cause any issues

[vojtechhabarta]

Thanks for the response.
I think I tried mvn install first and since it didn't work I used mvn clean install which I hoped should fix it but it was the same.

[IzakMarais]

I have the same issue. I sometimes see that not all .class files get generated, which causes errors in the tests. When I close VSCode and rerun mvn clean install it works. Also doing mvn install instead of mvn clean install didn't fix the problem.

[IzakMarais]

This fix that excludes the target folder from watched files seems to work.
