>>> [RPM] %post(maven-1:3.9.11-1.fc43.noarch) scriptlet failed, exit status 2   

Expected Results:
The installation should succeed.

Additional Information:
If the system has bash-5.2.37-3.fc43.x86_64, the issue doesn't happen. The issue is visible only with bash-5.3.0-1.fc43.x86_64.

The problem was also discussed in https://github.com/rpm-software-management/rpm/issues/3865 and it seems that using a single command for update-alternatives may fix the problem.

The %post scriptlet for maven is currently using a multiline command:
