adding with current classpath a resource?

[Sonar, Nishant]

Hello,

 

I want to add a reference (folder) for the current classpath

 

Ie .i wanna set something as

 

Classpath=classpath;some/folder/ref

 

Through sirefireplugin

 

I am not getting what to write for existing 'classpath'

 

I wrote as

 

<plugin>

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

      <artifactId>maven-surefire-plugin</artifactId>

      <configuration>

 
<argLine>-classpath=${classpath};${project.build.outputDirectory}\somedi
r</argLine>

      </configuration>

</plugin>

 

 

The maven is not taking ${classpath} it says null , I also 

Tried
{maven.test.classpath},{maven.compile.classpath},{maven.compile.classpat
h} 

But all are giving null

 

How to use current classpath here and add something to that classpath in
surefire plugin

 

Thanks

Nishant Sonar
