   Hi Experts,
   
   I get this error even when I run mvnd -v:
   PS D:\_Projects\Java\xxx> mvnd -v
   mvnd native client 0.7.1-windows-amd64 (97c587c11383a67b5bd0ff8388bd94c694b91c1e)

   Yes, the exception clearly indicates the registry has been corrupted.  We should put some safeguard mechanism to handle this use case more gracefully.  As indicated by @garywhittington, deleting the `$HOME/.m2/mvnd` should be a good workaround.

   The same problem started for me today.  I resolved it by removing the $HOME/.m2/mvnd directory, and then all seems to be working again (with mvnd then recreating this directory).
