Force Gradle to use specific Java JDK Version

If you want your Gradle tool to make use of a specific version of Java JDK, then you can follow the below steps.

Option 1:

1. Open your Java Project that is based on Gradle Build.
2. Make sure to set the JAVA_HOME environment variable to the JDK version you want to use.
3. Now open the build.gradle file.
4. Add the below lines.

   tasks.withType(JavaCompile) {
       options.fork = true
       options.forkOptions.executable = "${System.getenv('JAVA_HOME')}/bin/javac"
   }
   

Option 2:

If you wish to not to change any configuration, you can do that by using the terminal to run the gradle build command with a -D option to force set the java.home temporarily.

./gradlew build -Djava.home=/path-to-your-java-jdk/
