I have a Maven Groovy project and in pom.xml have:
    <build>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <dependencies>
                    <dependency>
                        <groupId>org.codehaus.groovy</groupId>
                        <artifactId>groovy-eclipse-compiler</artifactId>
                        <version>2.7.0-01</version>
                    </dependency>
                </dependencies>
                <configuration>
                    <compilerId>groovy-eclipse-compiler</compilerId>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
            </plugin>
            <plugin>
                <artifactId>groovy-eclipse-compiler</artifactId>
                <groupId>org.codehaus.groovy</groupId>
                <version>2.7.0-01</version>
                <extensions>true</extensions>
            </plugin>
        </plugins>
    </build>

If I have a syntax error in a Groovy file and the compiler fails when I build the project from the IDE, then I can not click on the failure in the output window and be taken the file and line even though the line number and other information is available in the output window. I need to manually go to the file and then goto the line number. Nothing in the output window is turned into a link for Groovy syntax or compile errors where as for Java it is.
