Java class inside the gradle build file fails

leftShift is deprecated in Gradle now.

I am trying to add a java class initialization inside the gradle build file like below:

task javaClassInGradleTask {

doLast {
    class Myclass {

       public void message() {

          System.out.println("this is message from java class");

       }

   }

   Myclass testObject = new Myclass();

   testObject.message();
 }
}

and I am trying to run the file:

gradle javaClassInGradleTask

My error result is below

FAILURE: Build failed with an exception. * Where: Build file '/Users/folder/build.gradle' line: 3

  • What went wrong: Could not compile build file '/Users/folder/build.gradle'. startup failed: build file '/Users/folder/build.gradle': 3: Class definition not expected here. Please define the class at an appropriate place or perhaps try using a block/Closure instead. at line: 3 column: 2. File: BuildScript @ line 3, column 2. class Myclass { ^

    1 error

  • Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

  • Get more help at https://help.gradle.org

BUILD FAILED in 0s

But when I try to add the class using leftShift it works well.

Any idea to add class inside the gradle file?

It doesn't work for both doLast and <<. Try:

task javaClassInGradleTask {
  doLast {
    Myclass testObject = new Myclass()
    testObject.message();
  }
}

class Myclass {
  public void message() {
    System.out.println("this is message from java class");
  }
}
