Cause

Failures in EcoreCustomUtil.getModelVersion are caused by uploads of a non-snapshot file or a corrupted one (via incorrect manual modification or due to a problematic transfer/download).

Resolution

Make sure you're uploading a valid snapshot file that is not manually edited or in any other way corrupted (copying snapshots between VMs or downloading very large files is a common cause for this).
Try to download the snapshot file again. If the file is with a bigger size you could choose to exclude the attachments as described in this wiki page: Moving attachments.
If the problem persists validate the integrity of the ZIP file (the actual steps depends on the operating system of the client machine).
Other workarounds:

- Downloading the snapshot directly from the source Jira server, they are located in %JIRA_HOME%\export\snapshots.
- Also, it's possible to use application links and deploy the snapshot directly from the source instance, this way CMJ handles the transfer.
