MAVEN, Netbeans Platform : Could not find the main class

I follow this tutorial :https://platform.netbeans.org/tutorials/nbm-maven-crud.html and I have an issue.

I tried to create the sample "maven crud sample application" and my "maven netbeans application" and I get always the same error. When I run the project, I get the following exception: 

--- nbm-maven-plugin:3.3:run-platform (default-cli) @ application ---
Executing: /bin/sh -c "/home/pea-rep/NetBeansProjects/JDK6/test maven//MavenCRUDSample/application/target/foo/bin/foo" --userdir '"/home/pea-rep/NetBeansProjects/JDK6/test maven//MavenCRUDSample/application/target/userdir"' -J-Dnetbeans.logger.console=true -J-ea --branding foo --jdkhome /usr/local/java/jdk1.6.0_45
Exception in thread "main" java.lang.NoClassDefFoundError: maven//MavenCRUDSample/application/target/userdir/var/log/heapdump/hprof
Caused by: java.lang.ClassNotFoundException: maven.MavenCRUDSample.application.target.userdir.var.log.heapdump.hprof

        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

Could not find the main class: maven/MavenCRUDSample/application/target/userdir/var/log/heapdump.hprof. Program will exit.

In this tutorial, I don't see any modification to make at the main class

I did the same tutorial without MAVEN and it works : https://platform.netbeans.org/tutorials/nbm-crud.html

With this error, I can't run my application and have my netbeans platform window. Someone knows why I have this?

I'm on Netbeans 6.9.1 with jdk1.6.0_45 and maven-3.2.1 OS : Ubuntu 64bit

edit : I've got 4 pom.xml :

Parent : crud-sample-application – netbeans Platform Application

crud-sample-application – Netbeans Platform based application

crud-sample-application – Platform application branding ressources

crud-sample-application – sample Netbeans Module

Sorry I wasn't able to split it.

I use netbeans for run my application ==> run project : 

install nbm:run-platform

run project via main() :

process-classes org.codehaus.mojo:exec-maven-plugin:1.1.1:exec

avec les arguments : 

exec.classpathScope=${classPathScope}
exec.args=-classpath %classpath ${packageClassName}
exec.executable=java "

Thanks, M.

Problem solve, When netbeans execute :

 /bin/sh -c "/home/pea-rep/NetBeansProjects/JDK6/test maven//MavenCRUDSample/application/target/foo/bin/foo" --userdir '"/home/pea-rep/NetBeansProjects/JDK6/test maven//MavenCRUDSample/application/target/userdir"' -J-Dnetbeans.logger.console=true -J-ea --branding foo --jdkhome /usr/local/java/jdk1.6.0_45

It doesn't like the space between maven and test. I rename my folder and it works.
