I do have Maven installed and in path, as given by mvn.bat -v .

I looked at abcl-asdf in the provided link and did some checking from
within ABCL.
The outputs of abcl-asdf::find-mvn, abcl-asdf::mvn-version were OK.
Interestingly, I don't have abcl-asdf:mvn-home defined.  Is my asdf
3.1.7.27 obsolete?

Triggers error:
Java exception 'java.lang.ClassNotFoundException: com.sun.jna.Native'.

My jna is under my home directory in
"c:/Users/977315/.m2/repository/net/java/dev/jna/jna/4.2.2/jna-4.2.2.jar"

That directory is non in CLASSPATH

Thanks,

Mirko
