Integrating Karma JavaScript testing with Maven

Question

I'm adding Karma-based JS unit tests to Maven. I used the following configuration:

<plugin>
    <groupId>com.kelveden</groupId>
    <artifactId>maven-karma-plugin</artifactId>
    <version>1.0</version>
    <executions>
        <execution>
            <goals>
                <goal>start</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <browsers>Chrome</browsers>
    </configuration>
</plugin>

Tests work separately (without Maven) on my machine when I use karma start karma.conf.js, but with Maven I got the following error:

[ERROR] Failed to execute goal com.kelveden:maven-karma-plugin:1.0:start (default) 
on project web: There was an error executing Karma. Cannot run program "karma":

Here is why I find it a bit strange: according to this class, the karma.conf.js should be found by default (@Parameter(defaultValue = "${basedir}/karma.conf.js", property = "configFile", required = true)). Also, I tried to pass the path, absolute and relative, in the -DconfigFile=... parameter, it didn't work. I used Windows, but I think it shouldn't be a problem. I'm not sure what exactly can be wrong in the configuration, an advice would be appreciated.

I think it was a bug, that's already fixed.

I tried to run tests again with version 1.2-SNAPSHOT of this plugin (cloned it and built) and it started the Karma properly.
