The following message displays when you deployed a project that has already been deployed successfully before.
The current library list is different from the library list contained within this project. The project library list has been updated. Refresh build options for the changed list and try again.
Cause:
The PBL list was updated (for example, with new or deleted PBLs) after it was first successfully deployed.
It is a known issue that it takes a project (especially a large project) a long time to display this prompt. This issue will be addressed in the later release.
Solution:
Build and deploy the project again.
