Describe the bug
The Export process is happy to export things that can’t be Imported.

To Reproduce
Populate a Maven repository.
Export thus produces the necessary files that can be verified through import-checker but cannot be imported, the import process is successful but the following task is failed.

Expected behavior
If the import is impossible so must be the export...
