Unable to upload the project files

[Hamilton_Tenório_da_]

I am triyng to build an existing project and I am receiving the message "Unable to upload project files". I checked all the assets and it seems OK.

The error message shows:

ERROR (-7) from "client:upload-manager": Error in zipping package asset files: .

I deleted the plugin folder and recreated it. I remove the files from the server too. No success. 

I tested others projects with similar plugins and they work normally. 

What I can do to solve this? What means these errors? Thanks.

Hamilton -- did you review this thread? https://software.intel.com/en-us/forums/intel-xdk/topic/673452 Perhaps there's something in your project file that is causing the problem.

I had checked that post before. No success.

The solution was create another project, copy everything to the new one. Now is OK. I do not understand why... This was an old project, builded several times before. 

This workaround works. It is a solution.
