Using GMavenPlus to run spock groovy tests alongside java junit tests from maven surefire

Question

I am trying to run "spock groovy tests alongside java junit tests from maven surefire"

I followed the examples

• https://github.com/groovy/GMavenPlus/wiki/Examples#joint-compilation &
• https://github.com/groovy/GMavenPlus/wiki/Usage#configuring-gmavenplus-1

When I have the gmavenplus + groovy plugins defined in the pom, the groovy test runs but not the java test.

When I have the gmavenplus + groovy plugins removed from the pom, the java test runs but not the groovy test.

The files I have are

• src/main/java/org/gw/JavaClass.java

   package org.gw;
  
   public class JavaClass {
   }
  

• src/test/java/org/gw/JavaTest.java

   package org.gw;
  
   import org.junit.Test;
  
   public class JavaTest {
  
       @Test
       public void testMethod1() {
           System.out.println("testMethod1");
       }
   }
  

• src/test/groovy/org/gw/GroovyTest.groovy

   package org.gw
   import spock.lang.Specification
   import spock.lang.Unroll
  
   @Unroll
   class GroovyTest extends Specification {
  
       def 'do a spock test'() {
           when:
           def doa = "spock test"
  
           then:
           println("done a " + doa)
       }
   }
