Internal compiler error: java.lang.NoClassDefFoundError: org/eclipse/jdt/core/search/SearchPattern

[Eskibear]

Open this simple maven project in vscode, I see two build errors, might be related to lombok support from detailed message.

After reloading window, errors are gone. I only copied one of the two diagnostics as below:

[{
	"resource": "/C:/Users/admin/git/microsoft/vscode-maven/test/projects/multi-module/module1/src/main/java/com/mycompany/app/App.java",

It is an upstream lombok issue.
Steps to reproduce

• enable lombok
• open simple maven project
• close all editors
• clean the workspace

After reloading window, errors are gone

I can reproduce the issue even after reloading the window if close all editors.

@Eskibear could you check VS Code 1.17.4?
Please clean the workspace after updating to 1.17.4

[Eskibear]

could you check VS Code 1.17.4?

I tried reloading a couple of times, and the issue didn't occur.
Because I was not able to stably reproduce it, I'm not sure if it indeed fixes the issue, or just due to good luck. I suggest that you open a PR so we can dig deeper and see if that's really related.

There is an issue in lombok.

I suggest that you open a PR so we can dig deeper and see if that's really related.

VS Code 1.17.4 includes a workaround. I will try to find a better fix.

I was not able to stably reproduce it

You can

• run VS Code 1.16.0 or pre release
• try Steps To Reproduce

I can repo this issue with just opening https://github.com/redhat-developer/vscode-java/tree/master/test/resources/projects/maven/salut (or gradle/simple-gradle, gradle-11, maven/salut-java11, these projects all can repro).

• Operating System: windows/mac/linux
• JDK version: 17.0.6
• Visual Studio Code version: 1.77.1
• Java extension version:1.17.0

[Eskibear]

I also repro it in codespaces with spring-petclinic these days. Then I disabled lombok support via settings as a workaround.

FYI @testforstephen @rgrunber @jdneo

@Eskibear @v-yuyul thanks for the information. I'm testing whether it's caused by the PR #3031. If so, we need to revert this PR.

There is an issue in lombok.

@snjeza Is there any issue tracking this? Can you link it here so people can have more context info?

[testforstephen]

This new regression seems to happen more frequently (in new machine) than the old regression #2887, I would like to revert to the previous version 1.18.24 until this issue is resolved.

@snjeza If you have found the root cause about this new regression, could you pls open a pull request to the upstream Lombok project?

[snjeza]

If you have found the root cause about this new regression,...

@testforstephen It is caused by projectlombok/lombok@afceb13
You may want to take a look at projectlombok/lombok#3403
I have created a workaround for jdtls.

could you pls open a pull request to the upstream Lombok project?

I will try
projectlombok/lombok#3378 fixes the issue.
