Actual result

Some strange warnings are observed.

Unresolved imports/types have been detected during analysis. Enable DEBUG mode to see them.
Use of preview features have been detected during analysis. Enable DEBUG mode to see them.

With --debug output contains

All warnings are related to classes javax.xml.stream.*, which are inaccessible somehow during analysis.

Hi,

In general, warnings can be ignored. For the first one, it’s likely that analysis isn’t finding all your libraries.

 
HTH,

The thing is I use no libraries, other than JDK standard ones.
