Maven build fails with "Cannot create a resource for"

[DonatasC]

Checked out the project from GitHub, and ran

mvn deploy

Got:

I found the source of the above problem. In pom.xml instead of:

<argument>${project.basedir}/workflow/generateGenModel.mwe2</argument>
<argument>-p</argument>
<argument>rootPath=${project.basedir}/..</argument>

we must have "/" added at the beginning of paths:

<argument>/${project.basedir}/workflow/generateGenModel.mwe2</argument>
<argument>-p</argument>
<argument>rootPath=/${project.basedir}/..</argument>

Thank you very much. It was the problem in my case as well.
