What version of liquibase are you using? Has this worked before? If so, what has changed since it worked? When you run the command, what log level are you using? If you are using anything less than DEBUG, can you re-run the command with it set at DEBUG and share the results?

I’ve got some clues, but nothing definitive. Here is what I did.

First, I went to github and found the 3.4.2 release tag. I then downloaded a zip file of the source code from that release and unzipped it, then opened it in my IDE (IntelliJ). I then found the source file at the top of the stack trace, and found line 118, the source of the NullPointerException. Here is the code in question, with some surrounding code for context.

LIQUIBASE column. See if that is in fact the case. If so, then something is a bit strange, because Liquibase tries very hard to ensure that the table exists and has the right columns, etc.

Something strange is happening and file paths are being created in a strange way. The included file path seems to have two parts to it - 

the first is 
I am not sure if that is a problem with your configuration or an actual bug.
