RE: clover plugin problem

[Vincent Massol <vi...@massol.net>]

Hi Charlie,

 

I’m answering on the maven list as this is the right location where to ask
questions. Please use the list in the future.

 

I don’t know what’s wrong in your case but I know how to find the answer.
Please run maven in debug mode (-X) and check the console logs. More
specifically look for the string “Parameter list being passed to Clover
CLI:” and check the parameters. Let us know what you find so that we can fix
this NPE.

 

Thanks

-Vincent

Subject: clover plugin problem

 

Hi,

I am trying to get clover maven 2 plgin working but seem to have run into a
problem during first off db generation. Here is the snipet of my pom: 

....
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-clover-plugin</artifactId>
<configuration>
<jdk>1.5</jdk>
</configuration>
<executions>
<execution>
<phase>pre-site</phase>
<goals>
<goal>instrument</goal> 
</goals>
</execution>
</executions>
</plugin>
......
The I run mvn site and I am getting a error:

[INFO] Preparing clover:instrument

ation.
