problem

1. after upgrade Extension: Language Support for Java(TM) by Red Hat to v1.33.0. Got error:

[{
	"resource": "/c:/Users/ww/work/test/project-for-test/test2/src/main/java/com/test2/Test2.java",
	"owner": "_generated_diagnostic_collection_name_#5",

	"source": "Java",
	"startLineNumber": 9,
	"startColumn": 15,
	"endLineNumber": 9,
	"endColumn": 22
}]

2. Change Extension: Language Support for Java(TM) by Red Hat to v1.32.0. It's OK.
3. Keep Extension: Language Support for Java(TM) by Red Hat with v1.33.0.
   • copy Data1.java to Data2.java and delete comments.
   • Data2.builder().build() is ok

There seem to be several issues related (or unrelated) to the Javadoc comments of the @Builder class in the latest Lombok 1.18.34. (issue 1, issue 2)

The version of Lombok bundled in this extension is from https://projectlombok.org/lombok-edge.jar, which currently delivers the same binary as Lombok 1.18.34, thereby affecting this extension.

Temporary solutions I discovered:

• Downgrade this extension to v1.32.0
• Or use the lombok/lombok-1.18.33.jar bundled in v1.32.0
  • Overwrite the jar file in the same path of the current version, or build and install the .vsix file yourself

Steps to overwrite

Windows PowerShell environment:

# Get and extract vscode-java v1.32.0 binary
curl.exe -LO "https://github.com/redhat-developer/vscode-java/releases/download/v1.32.0/vscode-java-1.32.0-220.vsix"
Rename-Item "vscode-java-1.32.0-220.vsix" "vscode-java-1.32.0-220.vsix.zip"
Expand-Archive -Path ".\vscode-java-1.32.0-220.vsix.zip" -DestinationPath ".\temp_ext"

# Copy .jar file
Copy-Item "temp_ext/extension/lombok/lombok-1.18.33.jar" "$env:userprofile/.vscode/extensions/redhat.java-1.33.0-win32-x64/lombok/lombok-1.18.33.jar"

# Remove downloaded files
Remove-Item -Recurse -Path "temp_ext","vscode-java-1.32.0-220.vsix.zip"

Linux-like environment:

# Get and extract vscode-java v1.32.0 binary
curl -LO https://github.com/redhat-developer/vscode-java/releases/download/v1.32.0/vscode-java-1.32.0-220.vsix
# or wget:
# wget https://github.com/redhat-developer/vscode-java/releases/download/v1.32.0/vscode-java-1.32.0-220.vsix
unzip -d temp_ext/ vscode-java-1.32.0-220.vsix

# Copy .jar file
# Replace .vscode with .vscode-server if you're in remote environment (like wsl, docker or ssh)
cp temp_ext/extension/lombok/lombok-1.18.33.jar /home/$(whoami)/.vscode/extensions/redhat.java-1.33.0*/lombok/lombok-1.18.33.jar

# Remove downloaded files
rm -rf /tmp/temp_ext vscode-java-1.32.0-220.vsix

@heguro Lombok version is 1.18.12 in my demo project. Before this extension v1.33.0, it was working fine.

Is it fixed in the latest version

[foxpluto]

Which version are you referring? I have the Language Support for Java(TM) by Red Hat v1.35.202408 and the bug is still there.

[iwangbowen]

when this will be fixed

[Kas-tle]

Lombok has merged a fix as of a few days ago (see https://github.com/projectlombok/lombok/pull/3726), but they have not done a release yet. So I assume that will have to happen first so that an updated version of Lombok can be bundled with the extension.

https://github.com/redhat-developer/vscode-java/issues/3561#issuecomment-2442023671 woke me up. Could someone try the vscode-java pre-release and see if the problem is resolved ? According to https://github.com/redhat-developer/vscode-java/blob/0f89a67eaf7a0189e3da172a02e277d128a96cc7/gulpfile.js#L132 (the 1.18.33 label we give is wrong, but it's definitely the latest), we're using the latest lombok edge release, which is from 2024-10-18. That definitely should have the fix. If it doesn't work then the problem was never fixed by the PR.

With the currently used Lombok v1.18.34 this is still an issue. Updating to v1.18.36 should fix it (relevant commit: https://github.com/projectlombok/lombok/commit/1ac3950a9e8d1c2da0ff0d6400386a9b345b23a2). At least it did so for the Eclipse IDE.
