Maven Exec Plugin : How configure the working directory

Question

I\'m using the Exec Maven plugin with the following command :

mvn exec:java

and I didn\'t manage to set the working dire

Answer 1

If you like to set it via calling mvn exec:java ... you need to go via the property like this:

mvn exec:java -Dexec.workingdir=Folder ...

which has nothing to do what you defined in your pom cause calling the goal exec:java is not part of the life cycle.

Answer 2

I couldn't either find a working fix, however an ugly workaround that was applicable in my case is to simply pass ${project.build.directory} (or any maven property for the matter) as an argument to the main class and handling it from there.

<configuration>
    [...]
    <arguments>
        <argument>${project.build.directory}</argument>
    </arguments>
    [...]
</configuration>

Setting the current working directory inside the code to properly simulate the non-working workingDirectory configuration is a bit tricky if you insist doing so, check this linked answer for more information.

Answer 3

I didn't found solution with exec:java.

So, now I use exec:exec instead because we can set the workingDirectory and it' OK.
