No progress after installing Maven & Aether Core.  Do I need to install
something else?

Details:

I installed JDK (needed for Maven), and Maven, and Aether Core
Now I have Java 1.8.0_0112.  I have updated Windows' PATH
to include all three (so that maven -v gives the expected output:

C:\>mvn -v
C:\
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5;

These aren't errors, per se, but warnings.  The system is attempting to
load your local version of ASDF from
<file:C:/mv-program-files/my-lisp-libraries/asdf/>.  Unless there is a
compelling reason to try to change the ASDF definition at runtime, I
would remove your local ASDF version and stick to the one that ABCL
ships with.


OK, I will try that.

Do you have a version of Maven installed locally?  ABCL-ASDF uses the
Maven Aether library to locate and download jna-4.2.2.jar, which
provides the necessary JNI voodoo for CFFI to work.






This message in a known obscurity in ABCL that should be corrected.
