Clover can't instrument Groovy test classes due to java.io.NotSerializableException on creating ConfigDir

[Dustin Pearce]

We have our maven build setup to run Groovy based integration tests. We want to be able to instrument our tests using distributed coverage while our app runs on a local jetty instance. This works great with Java based Junit tests but we are having trouble getting the Groovy tests instrumented.

When the build starts up with Clover the plugin throws the following stacktrace:

{code}

ERROR Could not create Clover Groovy configuration file. No Groovy instrumentation will occur. com.atlassian.maven.plugin.clover.DistributedCoverage

Hi Dustin,

I've made a SNAPSHOT release of the Clover plugin for Maven2 that contains a candidate fix for this problem. To use it, you'll need to specify the snapshot version:

<plugin>

 <groupId>com.atlassian.maven.plugins</groupId>

 <artifactId>maven-clover2-plugin</artifactId>

 <version>3.1.3-SNAPSHOT</version>

</plugin>

Note that this snapshot version is only available from Atlassian's public snapshot repository, which you may need to add to your pom also:

<repositories>

        <repository>

          <id>atlassian-m2-snapshot-repository</id>

          <name>Atlassian Public Snapshot Repository</name>

          <url>https://maven.atlassian.com/public-snapshot</url>

        </repository>

</repositories>

Please let me know how you get on with this build.

Regards,

-Brendan
