Vscode-java: JAVA_HOME with jenv on MacOS

[nedlowe]

I am managing JAVA_HOME using jenv. I get the error 'The JAVA_HOME environment variable points to a missing folder'.

From the terminal:
loweedw$ echo $JAVA_HOME
/Users/loweedw/.jenv/versions/1.8

loweedw$ ls -l $JAVA_HOME
lrwxr-xr-x 1 loweedw Users 64 7 Aug 00:40 /Users/loweedw/.jenv/versions/1.8 -> /Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home

I set java.home to the exact same value, and it seems to work fine.

Environment

• Operating System: MacOS
• JDK version: jdk1.8.0_181
• Visual Studio Code version: 1.30.1
• Java extension version: 0.36.0

Steps To Reproduce

1. Install jenv
2. jenv enable-plugin export # To automatically set JAVA_HOME
3. Install and load the Java plugin to VS Code

Most likely this is the way code works. It seems it only picks up environment variables when it's launched from the terminal.

• open Dev tools (Command Palette >Toggle Developer Tools)
• in the console, check what is the output of console.log(process.env)

Same issue happens to me, I fix this by setting "java.home" in "USER SETTINGS"
{
"gitlens.advanced.messages": {
"suppressShowKeyBindingsNotice": true
},
"files.encoding": "iso88591",
"explorer.confirmDelete": false,
"editor.largeFileOptimizations": false,
"java.home": "/Library/Java/JavaVirtualMachines/jdk-11.0.3_7.jdk/Contents/Home",
}

For me I pointed to the version in jenv for java.home in settings.json. For my machine, it looked like:

"java.home": "/Users/blimmer/.jenv/versions/openjdk64-1.8.0.212

Would be nice if VS Code could pick which JDK to use based on the .java-version file of a given project who's using jenv to manage JDKs.

This PR https://github.com/redhat-developer/vscode-java/pull/1104 should resolve the issue.

Enabling export plugin for jenv worked for me
jenv enable-plugin export
