Running Groovy using Maven2

Last week I wrote a post about GroovyWS (GroovyWS terrifies me! - DZone Big Link on 09/27 - thanks everyone!).

Using Eclipse Galileo I created Maven2 project and added Groovy nature. Eclipse automatically took care of the Groovy runtime so I was able to run Groovy classes just as they were standard Java classes.

Today I will show you how to run Groovy classes (here Groovy JUnit tests) using Maven2.

Setting up the project

Please do refer to my previous post: GroovyWS terrifies me!. Complete working download can be find at the end of this post.

Running tests using Maven2

When you execute standard Maven2 test command:

mvn test

Maven2 doesn't pick-up and execute Groovy test:

C:\Studies\PhD\workspace\cxf-and-groovy>mvn test
[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[INFO] Building Simple CXF project using spring configuration
[INFO]    task-segment: [test]

We have to make Maven2 aware of Groovy in order to pick-up and execute Groovy classes.

First, I added gmaven-runtime-default into Maven's dependencies list:

<dependency>
<groupId>org.codehaus.groovy.maven.runtime</groupId>
<artifactId>gmaven-runtime-default</artifactId>
<version>1.0-rc-3</version>
</dependency>

Then, I appended gmaven-plugin to following execution goals:

<plugins>
<plugin>
<groupId>org.codehaus.groovy.maven</groupId>
<artifactId>gmaven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>generateStubs</goal>
<goal>compile</goal>
<goal>generateTestStubs</goal>
<goal>testCompile</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>

Running Groovy JUnit tests

I re-ran the test and was surprised to see the following error:

C:\Studies\PhD\workspace\cxf-and-groovy>mvn test

Fixing the test failure I opened C:\Studies\PhD\workspace\cxf-and-groovy\target\surefire-reports\org.xh.studies.ws.cxfandgroovy.HelloWorldTest.txt file and saw:

-------------------------------------------------------------------------------

I did some googling and find out this:

http://jira.codehaus.org/browse/GMAVEN-36

The bug is still open, but in comments there is a workaround which basically boils down to adding the following property into pom.xml file:

<properties>
<gmaven.runtime>1.5</gmaven.runtime>
</properties>

This time, when I re-ran my test I saw lots of Apache CXF debug messages and finally:
