Type: Bug

Thank you for the great work on the Java support for VS Code.

Sadly large projects seem to struggle with "Connection to server got closed. Server will not be restarted." issue.

Steps to reproduce:

  1. Checkout https://github.com/keycloak/keycloak
  2. Open this project in VS Code

The CPU utilization remains over 200% even after the "Server will not be restarted" message.

It would be great if it would be possible to open Keycloak in VSCode.

@hmlnarik You may want to take a look at #2537 (comment)

Perhaps the following exception is related:

This exception is an upstream kubernetes-client issue - See https://github.com/fabric8io/kubernetes-client/blob/v5.12.2/crd-generator/api/src/main/java/io/fabric8/crd/generator/AbstractJsonSchema.java#L618
You can ignore it.

@snjeza Thank you for the hint.

The workflow I use sadly does not allow me to easily exclude other than non-java files, so including only a few selected modules is not possible for me.

Interestingly enough, the Netbeans Java Language Server opens the whole project in a few minutes without any tweaks in settings, with working symbol lookup, debugging etc. I'd love to use the recommended extensions like vscode-java, but the current behaviour does not allow me to; thus it rather seems to indicate an issue in vscode-java extension which could be investigated and improved?

Feel free to close this issue if it is not the case.

@hmlnarik You can try the following:

  • set
"java.jdt.ls.vmargs": "-Dsun.misc.URLClassPath.disableJarChecking=true -XX:+UseParallelGC -XX:GCTimeRatio=4 -XX:AdaptiveSizePolicyWeight=90 -Dsun.zip.disableMemoryMapping=true -Xmx4G -Xms512m",
"java.import.exclusions": [
        "**/node_modules/**",
        "**/.metadata/**",
        "**/archetype-resources/**",
        "**/META-INF/maven/**",
        "**/themes/**",
    ],

to your settings.json

git clone [email protected]:keycloak/keycloak.git
cd keycloak
./mvnw clean verify
code .

Thank you for the hint.

After following the suggestion, I am afraid I cannot report success. The IDE keeps reporting Building n% and Building [Done] messages after over 2 6 hours of indexing. When I tried "Go to symbol in Workspace", it returns results only in roughly 50% of cases.

If there is anything else I could try, please let me know.

EDIT: I ran Java: Clean Java Language Server workspace before opening the keycloak project.
