`java.jdt.ls.java.home` should use the Java execution environment name

Nenhum arquivo de implementação ou teste é especificado. Comece pelo tratamento de java.jdt.ls.java.home e java.configuration.runtimes, usando o exemplo .vscode/settings.json como ponto de entrada no nível do workspace. A tarefa estará concluída quando um projeto puder selecionar um runtime pelo nome do ambiente de execução, enquanto cada usuário resolve esse nome para seu próprio caminho do JDK.

Description

I've been trying to configure several Java projects in Visual Studio Code and have noticed that the java.jdt.ls.java.home setting, among others, is always required.

This setting belongs in the project's workspace (unless you work in one project, or have a perfectly aligned setup), but it cannot be set as such because for a multi-user project, each one will definitely have a different path for the JDK.

I think it would be great if this setting could take the (reference) value of one the existing Java execution environments instead, and tries to read the path of the corresponding JDK. This way, the configuration is fixed, set at the project level, and only needs to change if the project upgrades to a newer JDK.

For instance:

// Global User Settings
{
  ...
  "java.configuration.runtimes": [
    {
      "javadoc": "https://docs.oracle.com/en/java/javase/17/docs/api/index.html",
      "name": "JavaSE-17",
      "path": "/home/x80486/.local/share/mise/installs/java/temurin-17",
      "sources": "/home/x80486/.local/share/mise/installs/java/temurin-17/lib/src.zip"
    },
    {
      "default": true,
      "javadoc": "https://docs.oracle.com/en/java/javase/21/docs/api/index.html",
      "name": "JavaSE-21",
      "path": "/home/x80486/.local/share/mise/installs/java/temurin-21",
      "sources": "/home/x80486/.local/share/mise/installs/java/temurin-21/lib/src.zip"
    }
  ],
  ...
}

Then for each project I work on, I could just set in .vscode/settings.json:

{
  "java.jdt.ls.java.home": "JavaSE-21"
}

Additional Context

This is just an idea with the existing settings. It may be even more appropriate to define something new that could unify all the settings that request the location of the JDK, but it should always refer in one way or another to the java.configuration.runtimes (preferably by name), otherwise it's impossible to set this correctly —in a way that works for everyone regardless of the architecture and location/installation of the Java SDK—, at the project level.
