Intermittent UNKNOWN_EXCEPTION is thrown when retrieving metadata from Salesforce
Last updated 2016-12-08 ·Reference W-2926918 ·Reported By 5 users
When retrieving metadata from Salesforce using Force.com Migration Tool (Ant) or any other Metadata API tool you may get the following error:
UNKNOWN_EXCEPTION: An unexpected error occurred. Please include this ErrorId if you contact support: 2075718237-270444 (-652670408)
This error does not happen all the time, it occurs on the retrieval of the entire metadata package from an organization.
The issue is intermittent and is hard to reproduce consistently.
It can happen when Ant or another third party tool is retrieving a metadata package from Salesforce which contains many items.
Retry the retrieve operation
