Compile groovy mixed with java in Maven

Assuming that groovy codes are in src/main/groovy and java codes are in src/main/java.

We can use 2 maven-compiler-plugin to compile groovy and java, and add groovy-all dependency. And finally we can find the both groovy and java class files in jar.

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.2</version>
        <configuration>
          <source>${java.version}</source>
          <target>${java.version}</target>
          <encoding>${project.build.sourceEncoding}</encoding>
        </configuration>
      </plugin>

      <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.2</version>
        <configuration>
