Java Extension Pack Auto Config
https://github.com/cypher256/java-extension-pack#readme
If you are searching from an extension on VSCode, search for "jdk auto". All of the following are quoted from the Marketplace description.

The extension greatly reduces the installation, configuration effort, and JDK configuration errors for general Java developers. There is no need to manually install the JDK or set the JAVA_HOME environment variables. It also comes pre-included with extensions that most Java developers need, such as Maven, Gradle, Spring, Lombok, and Tomcat start/stop, so you can start developing right out of the box with zero configuration.

Features

JDK Auto-configuration

The JDKs are auto-configured for the current environment on VSCode startup as follows. You can check the detected JDK in User settings.json described later or Output (Ctrl + Shift + U) ≫ Dropdown: JDK Auto. If there are multiple JDKs of the same version, the latest minor version among them is used. If you manually install or update the JDK and want to force update the configuration of VSCode, restart VSCode or execute >Developer: Reload Window from the command palette (F1 or Ctrl/Cmd + Shift + P). These are applied as user (VSCode global) settings. You can manually change user settings, but if you want to customize your settings even further, consider using workspace settings or profiles.

1. Auto-fix invalid JDK configuration path (e.g. /jdk17/bin/java -> /jdk17)
2. Auto-remove configuration entries when JDK uninstalled or version path changed
3. Auto-scan from OS-specific location, SDKMAN, jEnv, jabba, ASDF, Gradle, Scoop, IntelliJ etc...
4. Auto-detect environment variables JAVA_HOME, JDK_HOME and PATH
5. Auto-download Adoptium LTS JDKs and available latest non-LTS JDK if not installed
6. Auto-update auto-downloaded JDKs to the latest version

(*1) The language server runtime used by VSCode extensions. Not for building and running projects.

(*2) Set latest LTS if unset, Fix if unsupported older version.

Auto-download Support

Up to 4 LTSs and the latest available non-LTS will be auto-downloaded if not installed. Unused old non-LTS that were previously auto-downloaded can safely be removed manually from the directory. Auto-download is supported on the following platforms:

• Windows x64
• macos x64, aarch64
• Linux x64, aarch64

The downloaded JDKs are stored in the following JDK Auto extension global storage directory.

e.g. Auto-configured User settings.json

"maven.terminal.customEnv": [
  {
    "environmentVariable": "JAVA_HOME",
    "value": "c:\\Program Files\\java\\jdk-17.0.6"
  }
],

Terminal Auto-configuration

Terminal profiles are defined based on configured runtimes, so you can easily open a terminal by selecting the Java version from command >Terminal: Create New Terminal (With Profile) or Terminal (Ctrl/Cmd + ) ≫ Profiles dropdown. The configured environment variables have no effect outside the terminal, so the system and OS user environment remain clean. TheJAVA_HOMEandPATH` in the auto-configured terminal configuration will always be overridden from the configured runtimes, so if you want to customize it, copy the terminal configuration entry and create a new one.

A non-existent rcfile is specified so that JAVA_HOME and PATH are not overwritten at shell startup. If necessary, manually create the following rcfile.

Auto-default Settings

If the user settings is not set, it will auto-set the JDK Auto default value. Note that a debug run is required to enable Hot Code Replace (Hot Deploy).

Language Pack Auto-installation

The language pack corresponding to the OS locale is installed at the first startup.

• cs, de, es, fr, it, ja, ko, pl, ru, tr, zh-hans or zh-hant

Included Extension Features

Extension Pack for Java

Since many projects are nowadays using different Java versions in development, it is recommended to specify the Java version for each project instead of the JAVA_HOME environment variable so as not to affect the OS and OS user environment. To see which JDKs are used for your projects in multi-root workspaces, you can trigger the command Java: Configure Java Runtime in Command Palette. The Configure Runtime for Projects view is a feature of the Extension Pack for Java (Microsoft).

Change JDK for Gradle and Maven projects

If you want to change the JDK version for your Gradle or Maven projects, you need to update it in your build scripts (build.gradle or pom.xml). You can click ⓘ to see how to make such changes. Click 🖊 will navigate to the build script file of the project. Maven/Gradle version is recommended to be set per project in gradle-wrapper.properties/maven-wrapper.properties using wrapper gradlew/mvnw. For Spring Boot Gradle/Maven projects and general Gradle projects, these wrappers are included by default, so you don't need to install Gradle/Maven or set its environment variables.

Change JDK for unmanaged folders

To change the JDK for unmanaged folders (with out any build tools), you can click the 🖊 button. It will list all the JDKs and you can select one for your unmanaged folders. This changes the "default": true for java.configuration.runtimes. Currently, it is not possible to use different Java versions in multiple unmanaged folders within the same workspace.

Spring Boot Extension Pack

Set the JDK version when creating a Spring Boot project or in build.gradle/pom.xml.


Community Server Connectors

The JDK used to run the server for Servlet and Jakarta EE applications can be specified from the context menu ≫ Edit Server ≫ vm.install.path. The actual configuration files is in .rsp/redhat-community-server-connector/servers in the user home.


Included Extensions

The Extension Pack for Java is required. Other extensions can be disabled per workspace or uninstalled according to your preference. If you want to set up extensions and configurations by development language, consider Profile. (*) indicates that it will be installed if available in that environment at first startup.
