Symbols not getting resolved for lombok on vs code

[VincentLee-EN]

My "Language support for Java ™ for Visual Studio Code" is v1.38.0, Symbols not getting resolved for lombok on vs code，but it can still compile and run

1. when I use @slf4j，here comes errors:
   

2. when I use @DaTa, the same situation happens

@VincentLee-EN Could you attach a project example reproducing the error?

[VincentLee-EN]

How?

Is it because I'm using Java 17 that the plugin doesn't support it very well yet?

How?

You can try Paste, drop or click to add files

You need Java 23 to use javac - "java.jdt.ls.javac.enabled": "on",

My project uses Java17，is it a good idea to upgrade it to Java23?
Or if there is any better solution to user javac while Java version is 17?

here is my settings.json for java after I installed java23, but it didn't work, is the config is wrong?
"java.jdt.ls.java.home": "/home/vincent/tools/java/jdk-23.0.1",
"java.jdt.ls.javac.enabled": "on",
"java.configuration.runtimes": [
{
"name": "JavaSE-17",
"path": "/home/vincent/tools/java/jdk-17.0.12",
"default": true
},
{
"name": "JavaSE-23",
"path": "/home/vincent/tools/java/jdk-23.0.1",
}
],

My project uses Java17

Your project can use Java >= 1.8

[snjeza]

here is my settings.json for java after I installed java23, but it didn't work, is the config is wrong?

Could you try the following:

• install VS Code Pre-Release
• add <your_project>/.settings//org.eclipse.jdt.apt.core.prefs with the following contents

eclipse.preferences.version=1
org.eclipse.jdt.apt.aptEnabled=true
org.eclipse.jdt.apt.genSrcDir=.apt_generated
org.eclipse.jdt.apt.genTestSrcDir=.apt_generated_tests
org.eclipse.jdt.apt.reconcileEnabled=true

• Open the command palette (F1)
• select Java: Clean the Java Language Server Workspace
• select Restart and delete from the confirmation prompt

I followed these steps, and it did not resolve the issue for me.

I also reported this issue when javac experimental support is release and since then I switched back to ECJ.

@VincentLee-EN I can't reproduce the issue.
Please attach a project example reproducing the issue.

@VincentLee-EN I can't reproduce the issue. Please attach a project example reproducing the issue.

I don't know if this will work properly, since it is impossible to be completely consistent for the environment and configuration between you and me

@snjeza, you can try with this sample project. Lombok working fine with ECJ but failing when using Javac as the compiler(using JDK 23 for the language server).

I see the following errors in the Language Support for Java Output window:
