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

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:

...
<properties>
    <argumentA>defaultA</argumentA>
    <argumentB>defaultB</argumentB>
</properties>
...
<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.2.1</version>
    <configuration>
        <executable>java</executable>
        <arguments>
            <argument>-Djava.library.path=${project.build.directory}/lib</argument>
            <argument>-classpath</argument>
            <classpath />
            <argument>com.example.app.MainClass</argument>
            <argument>-a</argument>
            <argument>${argumentA}</argument>
            <argument>-b</argument>
            <argument>${argumentB}</argument>
        </arguments>
    </configuration>
</plugin>
...

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
