I try running (uiop/run-program:run-program '("where" "mvn.bat") :output :string)

On asdf 3.1.7, it returns the correct output.

With asdf 3.1.7.27 and 3.1.7.43. I get an error "Class not found: java.lang.UNIXProcess".

If I go to the top level, and try again, I get the correct result.

This is with:

C:\Users\977315>java -jar "c:\mv-program-files\abcl-bin-1.4.0\abcl.jar"

Armed Bear Common Lisp 1.4.0

Java 1.8.0_112 Oracle Corporation

The abclrc is minimal: load asdf and load quicklisp:

(eval-when (:compile-toplevel :load-toplevel :execute)

(let ((file "asdf.3.1.7.43.lisp"))

(load (merge-pathnames file

(user-homedir-pathname)))))

(eval-when (:compile-toplevel :load-toplevel :execute)

#-quicklisp

(let ((quicklisp-init (merge-pathnames "quicklisp/setup.lisp"

(user-homedir-pathname))))

(if (probe-file quicklisp-init)

(load quicklisp-init)

(error "Did not find ~a ... quicklisp not loaded" "~/quicklisp/setup.lisp"))))

I posted this on the ASDF mailing list, and Fare suggested this may be an ABCL-related

issue.

I hope all the problems I am having have one single root cause

- and that we discover it :-)
