you are using the latest released version not an snapshot, isn't it? The problem is on copyFromContainer folder. In beforeStop, I will take a look why a NullPointer is happening, but you can comment that lines as workaround.

Thanks for opening this issue which helps us in improve the Cube.

Sorry it is not an issue but a gist, well I will open it for you if you want :) BTW you can change this line:

${docker.serverIp}
to
dockerServerIp

https://github.com/arquillian/arquillian-cube#dockerserverip-and-containers

because it is automatically set by Cube since Alpha4

OK thanks, I will open an issue.
But the copy feature works with your exemple with tomcat ?
