Ignore folder from workspace

[s0meRandomDev]

Is it possible to speciffy the java language server to ignore some folders in the workspace ?
I would need this because if the language server does not have rights to read one of the folder, it will stop solving imports.

Environment

• Operating System: Linux Ubuntu 19.10
• JDK version: 8
• Visual Studio Code version: 1.45.0
• Java extension version: 0.61.0

Steps To Reproduce

1.Have a working java project in your workspace
2. Add a folder with no access rights
3. Language server cannot solve imports anymore.

@liteultom you can use the java.import.exclusions property. See redhat-developer/vscode-java#1084

"java.import.exclusions": [
        "**/node_modules/**",
        "**/.metadata/**",
        "**/archetype-resources/**",
        "**/META-INF/maven/**",
        "**/templater-front/**",
    ]
