Upgrade Mobilefirst CLI 6.3.0 to 7.0

Question

Are there any known issues in upgrading mobilefirst 6.3 CLI to mobilefirst 7.0 CLI ?

Auto-upgrade fails with the following error in ubuntu 14.0.x, where it was previously working just fine with 6.3.0.

Error when running mfp build -dd

While the upgrade issue using the CLI is being investigated under the APAR PI37526, you can open a PMR to follow it.

The error may also happen if the android\native folder is missing the project.properties file. Verify whether this file exists or doesn't exist in the android\native folder of your MFP project.

You can regenerate this file using the instructions here or via Google ADT's commandline tool.

As a workaround, you can import the 6.3 project into a MobileFirst Studio v7.0; I can at least confirm that when using the Studio the upgrade error mentioned in the question does not happen and the ProGuard files are being added to the upgraded project.
