Rudder

I built an archive containing techniques to use and test the new import API.
The first import works perfectly. After some testing I had to modify one of the technique, re-importing an archive with the updated technique without version change fails with the following error:

2023-10-26 08:51:40+0000 ERROR api-processing - SystemError: An error occurred; cause was: java.nio.file.NoSuchFileException: /var/rudder/configuration-repository/techniques/systemSettings/misc/cis_ubuntu20_audit_srv_2/1.0

The import did wipe all previous technique files in the /var/rudder/configuration-repository but did not commit the change nor did it unpack the new files from the archive in-place.
The error is very confusing as the archive is well construct and I was finally able to import it after:

1. removing all directives based on techniques from the archive
2. removing all techniques from the initial import in the technique tree
3. removing from the confiiguration repository all the files from the initial import
4. re-run the import on the updated archive

I am not sure on how the import is expected to behave, but this is very confusing for the end user and make the import/export usage very limited...
