Unable to open projects in 6.4RC


Some projects I upgraded to 6.4RC and I’ve been working fine just yesterday today DO NOT open in Cuba Studio.
With message: Unable to open the project, The project uses an application component that is not supported by this version of studio or was not found in both local Maven and https://repo.cuba-platform.com/content/groups/work repository

Sorry, my mistake,

Some problem here with the machinery.
There’s no problem as described.
