Does clover work with the groovy-eclipse-plugin?

I tried using clover 3.1.6 with the groovy-eclipse-compiler and I get the following error.

[INFO] Preparing clover2:instrument

[WARNING] Removing: instrument from forked lifecycle, to prevent recursive invocation.

[INFO] [enforcer:enforce {execution: default}]

Before switching from gmaven to groovy-eclipse-compiler it worked fine. We have been resolving these issues temporarly by switching out clover for cobertura, but this is not something we want to keep long term.

This bug https://jira.atlassian.com/browse/CLOV-1021 states that clover was enhanced to handle the groovy-eclipse-plugin with version 3.1.3. We are using version 3.1.6

Here is how we setup the groovy-eclipse-compiler

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<version>2.5.1</version>

<configuration>

<source>1.6</source>

<target>1.6</target>

<encoding>UTF-8</encoding>

<compilerId>groovy-eclipse-compiler</compilerId>

</configuration>

<dependencies>

<dependency>

<groupId>org.codehaus.groovy</groupId>

<artifactId>groovy-eclipse-batch</artifactId>

<version>1.7.10-06</version>

</dependency>

<dependency>

<groupId>org.codehaus.groovy</groupId>

<artifactId>groovy-eclipse-compiler</artifactId>

<version>2.6.0-01</version>

</dependency>

</dependencies>

</plugin>

What version of the groovy-eclipse-compiler does clover support?

[Marek Parfianowicz · Accepted solution]

Clover works with groovy-eclipse-compiler, however you have to put Groovy sources in a standard location, i.e. src/main/groovy or src/test/groovy.

If you put Groovy files in Java source folder (src/.../java - it's suggested on Groovy-Eclipse+compiler+plugin+for+Maven page, section "Setting up the source folders / Do nothing"), then a build fails with error like below:

[INFO] BUILD FAILURE
...

The bug CLOV-1144 has been reported to get rid of this limitation.

Please have a look at the manual:

• Compiling+Groovy+with+Groovy+Eclipse+Plugin

where you can find exemplary pom.xml for Maven 2 and 3.

There is also a manual for old GMaven plugin as well:

• Compiling+Groovy+with+GMaven+plugin

Thanks for the response Marek. I tried using clover2:setup and <extensions>true</extensions> but it appears that I am having the same issue. I will work on getting an issue logged at support.atlassian.com

[Marek Parfianowicz]

Have you tried to use 'clover2:setup'? You're using 'clover2:instrument' goal, which creates a parallel build lifecycle; and the groovy-eclipse-compiler also modifies a build lifecycle, adding extra phase, so it might be a case that they clash with each other. I've also noticed that you don't have "<extensions>true</extensions>" property defined for groovy-eclipse-compiler. See:

http://groovy.codehaus.org/Groovy-Eclipse+compiler+plugin+for+Maven

Hi,

From attached build log I cannot say what exactly went wrong. Could you raise an issue at support.atlassian.com and attach some code sample and a full build log from 'mvn -X' command?
