Could not run ltex-ls with Java, please see the output panel 'LTeX Language Client' for details.

[k2pctdn]

Describe the bug
Every time I open VS Code on macOS the LTEX error "Could not run ltex-ls with Java, please see the output panel 'LTeX Language Client' for details. You might want to try offline installation." appears.

Steps to reproduce
Steps to reproduce the behavior:

1. Just open VS Code with LTeX installed (Marketplace version) and the above error appears.
2. Clicking retry does not help.

LTeX configuration
Please paste all configuration settings starting with ltex. from your settings.json. You can help us by temporarily removing some irrelevant settings from your settings.json and see if the bug still occurs.

Version information
List here the version information of the relevant software.

• Operating system: macOS Ventura 13.1 (Apple Silicon M1)
• VS Code: 1.74.2
• vscode-ltex: 13.1.0
• ltex-ls: x.xx (only if not using ltex-ls automatically downloaded by LTeX)
• Java: x.xx (usually obtained with java -version, only if not using Java automatically downloaded by LTeX)

Additional context/information
The bundled Java exists in /Users//.vscode/extensions/valentjn.vscode-ltex-13.1.0/lib/ltex-ls-15.2.0/jdk-11.0.12+7

[adamaltmejd]

I get the same error (also on M1 Mac)

[BusHero]

I got the same error when running inside a dev container. It works however on Windows

[kir68k]

Had the same issue, which I resolved by installing ltex-ls through brew, and setting a few config options:

    "ltex.ltex-ls.path": "/usr/local",
    "ltex.java.path": "/Library/Java/JavaVirtualMachines/openjdk.jdk/Contents/Home"

The JAVA_HOME setting I figured out using this SO comment.

A new problem arises for me though, where VSCode is stuck on Starting LTeX..., without giving any errors, and there being an ltex-ls process running as reported in htop.
I do not know why this happens, especially as on Linux (Arch/Debian) it all works fine.

EDIT
On another machine running Ventura, I didn't have to do any of this, and only had to install the extension, then it works seamlessly...
