lsp-java doesn't detect core libraries on Apple M3 macbook air

[JoshTRN]

Describe the bug
The workspace fails to detect java core libraries and doesn't work on Apple M3 air.

Note

• I'm using spacemacs with the java layer which installs lsp-java
• Here's my java -version output:

openjdk version "21.0.3" 2024-04-16
OpenJDK Runtime Environment Homebrew (build 21.0.3)
OpenJDK 64-Bit Server VM Homebrew (build 21.0.3, mixed mode, sharing)

• This works in vscode and the java extension pack

To Reproduce
On Apple M3 macbook air:

• install latest jdk from homebrew brew install java(this should install 21.0.3)
• start fresh spring project through spring initializer using all the defaults and java 21
• enter the DemoApplication.java
• I also set the lsp-java-configuration-runtimes

  (setq lsp-java-configuration-runtimes '[(:name "JavaSE-21"
                                      :path "/opt/homebrew/Cellar/openjdk/21.0.3/libexec/openjdk.jdk/Contents/Home"
                                      :default t)])

Expected behavior
All the standard library and dependencies should be detected and all the standard lsp-java apis should function normally.

[AnonymusBadger]

Hi! I'm facing similar issue. @JoshTRN Ware you able to resolve this?

Describe the bug

The workspace fails to detect java core libraries and dependencies.
With lsp-java-configuration-runtimes The type java.lang.Object... goes away and I get some completion working for java core (I still get the error in log), but not for dependencies e.g. The import org.junit cannot be resolved

Note

• I'm using Doom Emacs on Arch Linux with the (java +lsp +tree-sitter) module
• java --version installed with jabba:

openjdk 21.0.2 2024-01-16
OpenJDK Runtime Environment (build 21.0.2+13-58)
OpenJDK 64-Bit Server VM (build 21.0.2+13-58, mixed mode, sharing)

• I have lsp-workspace-folder root set to same dir as where gradle init was run

To Reproduce

1. Install [email protected] with jabba
2. Initialize new Gradle 8.9 Application project with defaults (JUnit Juniper for testing)
3. Open example App.java or AppTest.java
4. Custom lsp-java-configuration-runtimes:

(after! lsp-java
  (setq lsp-java-java-path (concat (getenv "JAVA_HOME") "/bin/java"))
  (setq lsp-java-configuration-runtimes `[
                                          (:name "JavaSE-21"
                                           :path ,(getenv "JAVA_HOME")
                                           :default t)]))

5. .envrc:

PATH_add ~/.jabba/jdk/[email protected]
JAVA_HOME=~/.jabba/jdk/[email protected]

I've managed to fix it!

Setting lsp-java-jdt-download-url to https://www.eclipse.org/downloads/download.php?file=/jdtls/milestones/1.37.0/jdt-language-server-1.37.0-202406271335.tar.gz (latest jdtls release as of today (30.07.2024) fixed the issue.

The default jdtls in lsp-java is 1.26 which is older than JDK 21 release date.

'(lsp-java-jdt-download-url
   "https://www.eclipse.org/downloads/download.php?file=/jdtls/milestones/1.37.0/jdt-language-server-1.37.0-202406271335.tar.gz")

@AnonymusBadger worked for me, thanks for this!

I've just spent a million years trying to fix the error related to java version, just to find out it was an old JDT-ls version 🤦 for the fellow noobs who might be struggling:

• You can use setq to change the value of the lsp-java-jdt-download-url
• You can find the link to the current latest version here
• After setting the URL dont forget to reload/config and run M-x -> lsp-update-server
