Hi..
What you actually do here is to mix the configuration style og the
exec and the java goal. In the configuration of the java goal there is
no <classpath> element because it will automaticly be build based on
the project dependencies. Also I would remove the <systemProperties>
section (well that is if you do not actually need a system variable
with the key myproperty, and then i would reccomend renaming it :))
Please note that there was a bug in the java goal in the 1.0 version
of the plugin so please make shure you are using the 1.0.1 version.
Well. so the plugin config should then look something like this :
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.0.1</version>
<executions>
<execution>
<phase>[your wanted phase here. for valid ones see
http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html]</phase>
<goals>
<goal>java</goal>
</goals>
</execution>
</executions>
<configuration>
<mainClass>com.caribbeancricket.walcott.tools.ArticleImporter</mainClass>
</configuration>
</plugin
This is at least the setup that works for me. I see that a little more
documentation is needed on the mojo site.
But for any further question, please use the mojo user group .
Best regards

Hi All...
I'm trying to make the exec-maven-plugin run a java Main using the project's
classpath, but I'm running into trouble.
As per TFM I have specified the arguments thusly:
<arguments>
<argument>-classpath</argument>
<!-- automatically creates the classpath using all project
dependencies,
also adding the project build directory -->
<classpath/>
</arguments>
This gives me the nasty stacktrace at the bottom, using maven 2.0.2 and 2.0.4.
If I remove the classpath goop, it will attempt to run the specified class but
fails on the first dependency.
Anyone have any idea what is wrong?
