I tried to create a new project but it seems that the problem comes from netbeans configuration .

Could you help me please ? Thank you in advance !

Solution

It seems as if the maven exec plugin is not well configured. Have a look at the documentation: The plugin offers two goals exec and java

I am using the plugin with exec:java (run in same jvm) and you need to configure the MainClass like this:

        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>
            <configuration>
                <mainClass>your.context.MainClass</mainClass>
            </configuration>
        </plugin>

On the other case (exec:exec) you should specify the executable as described in the specification / sample
