Using Maven 'exec:exec' with Arguments

Question

I have a project configured to build and run with Maven. The project depends on platform specific native libraries, and I\'m using the strategy found here to manage those d

Answer 1

I managed to find a reasonably elegant solution to my problem using Maven environment variables.

The default values are defined as properties in the pom, and added to the exec plugin as arguments:

...

    defaultA
    defaultB

...

    org.codehaus.mojo
    exec-maven-plugin
    1.2.1
    
        java
        
            -Djava.library.path=${project.build.directory}/lib
            -classpath
            
            com.example.app.MainClass
            -a
            ${argumentA}
            -b
            ${argumentB}
        
    

...

Now I can run with default parameters exactly as I did before:

mvn exec:exec

And I can easily override the defaults for each argument at the command line using:

mvn exec:exec -DargumentA=alternateA -DargumentB=alternateB
