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>

          <source>${java.version}</source>

          <target>${java.version}</target>

          <encoding>${project.build.sourceEncoding}</encoding>

        </configuration>

      </plugin>
