Integrating Groovy with a Java EE application and Maven

[Mr Andersson]

Hi,

I can not find any info on this online that will actually work.
I've tried:

<dependency>
    <groupId>org.codehaus.groovy</groupId>
    <artifactId>groovy</artifactId>
    <version>2.4.7</version>
</dependency> as well as <plugin>
    <inherited>true</inherited>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.5.1</version>
    <configuration>
        <source>${java.version}</source>
        <target>${java.version}</target>

        <!--!!!!!!!!!!!!!!!! ALSO TRIED WITHOUT THESE TWO LINES !!!!!!!!!!!!!!!! 
-->
        <compilerId>groovy-eclipse-compiler</compilerId>
        <verbose>true</verbose>

        <!-- See: 
http://stackoverflow.com/questions/17944108/maven-compiler-plugin-always-detecting-a-set-of-sources-as-stale 
--> <useIncrementalCompilation>false</useIncrementalCompilation>
    </configuration>

    <dependencies>
        <dependency>
            <groupId>org.codehaus.groovy</groupId>
            <artifactId>groovy-eclipse-compiler</artifactId>
            <version>2.9.2-01</version>
        </dependency>
    </dependencies>
</plugin> but this results in an error when a Java class is referencing 
a Groovy class in the project. I am not using eclipse. What are the 
neccesary steps to get Groovy to work *seamlessly in a Groovy project in 
2016* ? What are the limitations? Thanks!
