I just make a simple project that has a mvnw script in its root directory, and then I ran following from root directory:

codeql database create  --source-root .   --language=java DB_Codeql

I also try to ran from parent directory such as

codeql database create  --source-root myMavenJavaPrj   --language=java DB_Codeql

I got following error messages:

it seems that the problem can be ./mvnw too (maybe) which should be just mvnw the main issue seems to be the space character that exists in one of my directories name.
