Groovy in Java EE with Maven

It is quite easy to add Groovy support. Once the support is in place you can use Groovy as you would use regular Java.  As a matter of fact to test out Groovy we will create a Struts2 action with it!

Following assumes we have set up a basic struts2 application using Maven:

1) In Netbeans, expand the "Project Files" and open pom.xml.

2a) Locate the maven compiler plugin, which in my poms typically looks like the following:

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>2.3.2</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                    <compilerArguments>
                        <endorseddirs>${endorsed.dir}</endorseddirs>
                    </compilerArguments>
                </configuration>
            </plugin>

2b) Edit this pom.xml such that the above looks like the following:

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>2.3.2</version>
                <configuration>
                    <compilerId>groovy-eclipse-compiler</compilerId>
                    <verbose>true</verbose>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>org.codehaus.groovy</groupId>
                        <artifactId>groovy-eclipse-compiler</artifactId>
                        <version>2.6.0-01</version>
                    </dependency>
                </dependencies>
            </plugin>
