Language Support For Java extension fails with NoSuchMethodError

[RScrusoe]

Setup:
I am on cursor. version: 0.50.7 02270c8441bdc4b2fdbc30e6f470a589ec78d600 arm64
I have installed the Extension Pack for Java today.
In my company project I need to use java 17 so have installed the java 17 using homebrew.
I have setup the below in user level settings.json

  "java.configuration.runtimes": [
    {
      "name": "JavaSE-17",
      "path": "/opt/homebrew/Cellar/openjdk@17/17.0.14/libexec/openjdk.jdk/Contents/Home",
      "default": true
    }
  ],

The same java version is also set in JDK runtime settings.

Now, when I restart the cursor ide, the output section of the Language Support For Java shows below.

Please help me understand what is this error and what are it's implications and how to fix?

Apologies for being noob to java!

This is a duplicate of eclipse-jdtls/eclipse.jdt.ls#3401, which was fixed at microsoft/vscode-gradle#1651 . Fixed in the pre-release builds of vscjava.vscode-gradle, version 3.17.2025032611 or newer. I don't think vscode-gradle has done a regular release of this though.

@rgrunber thank you, the latest pre-release version update solved the issue!
Thank you again for prompt response.

If you don't mind can you please tell me what is the implication of this error was? I am very new to Java setup on vscode and still not sure what exactly problem was and what was solved.

Very sorry to bother you!

The error probably resulted in a Gradle project not building correctly when a user has vscode-java & vscode-gradle installed. The original issue mentions it happening when running/debugging. vscode-java has its own embedded Gradle support, but vscode-gradle provides something that better simulates the build.

The problem occurred because vscode-gradle extends the language server (JDT-LS) provided by vscode-java, and provides its own builder. vscode-gradle set a particular version of those libraries and compiled against those. However, since they're separate extensions, there's no guarantee those exact same versions will exist at runtime. In fact vscode-java updates dependencies pretty quickly to take advantage of new features. One of those libraries changed the API for a method, and vscode-gradle could no longer call it, hence the NoSuchMethodError.

I give some details at eclipse-jdtls/eclipse.jdt.ls#3401 (comment) .

The fix was to update the library call : https://github.com/microsoft/vscode-gradle/pull/1658/files#diff-ed16cfe57849cb9870944f7b5efe15697e5d87576482bf9a5d3c50ff930fecc8R266 but also to ensure that vscode-gradle is compiling against latest version of those dependencies, so any issues show up at compile time, as opposed to at runtime : https://github.com/microsoft/vscode-gradle/pull/1658/files#diff-73639904a775a6d286ae2e5fc0c0aa50c45d83b225901f607d4a936d35bfa217
