Open Terminals by Java Version

This extension adds the Java versions available in your current environment to the VS Code terminal profiles dropdown. Select the Java version you want to use, open a new terminal, and you can check the version with the following commands. Although the latest versions of Gradle and Maven are bundled, it is generally recommended to use project-specific wrappers (gradlew, mvnw).

java -version
gradle -v
mvn -v

Set Default Java Version

The built-in Select Default Profile in VS Code only changes the default terminal profile. However, this extension applies the selected profile's Java version to all Java-related settings (⭐) within the user (global) settings.json.

To specify a different Java version for individual settings, edit the following files: <br> <br>

• General (vscode-java)<br> (*1) User settings.json (Java runtimes common settings)

  "java.configuration.runtimes": [
    {
      "name": "JavaSE-1.8",
      "path": "C:\\Program Files\\java\\jdk-1.8.0_402",
    },
    {
      "name": "JavaSE-11",
      "path": "C:\\Program Files\\java\\jdk-11.0.21",
    },
    {
      "name": "JavaSE-17",
      "path": "C:\\Program Files\\java\\jdk-17.0.12"
    },
    {
      "name": "JavaSE-21",
      "path": "C:\\Program Files\\java\\jdk-21.0.8",
      "default": true //⭐ default when creating "No build tools" project
    }
  ]
  

<br>

• Gradle (vscode-gradle) <br> (*1) User settings.json (Gradle execution runtime)

  "java.import.gradle.java.home": "C:\\Program Files\\java\\jdk-21.0.8" //⭐
  

  (*2) Project build.gradle (options.release)

  def javaVersion = 17
  java.sourceCompatibility = javaVersion // Makes it recognizable by VS Code
  compileJava.options.release = javaVersion // JEP 247: API validation
  

  The Gradle Toolchain allows you to specify the exact JDK version to use for building projects.

  java.toolchain.languageVersion = JavaLanguageVersion.of(17)
  

<br>

• Maven (vscode-maven) <br> (*1) User settings.json (Maven execution runtime)

  "maven.terminal.customEnv": [
    {
      "environmentVariable": "JAVA_HOME",
      "value": "C:\\Program Files\\java\\jdk-21.0.8" //⭐
    }
  ]
  

  (*2) Project pom.xml (maven.compiler.release)

  <properties>
      <!-- <maven.compiler.source>17</maven.compiler.source> -->
      <!-- <maven.compiler.target>17</maven.compiler.target> -->
      <maven.compiler.release>17</maven.compiler.release><!-- JEP 247: API validation -->
  </properties>
