Hi all, patch is attached. With it this kind of .asd spec works out of the box and resolves all JARs and puts them in classpath: (require :asdf) (require :abcl-contrib) (require :abcl-asdf) (require :jss) (asdf:defsystem #:test-asdf :serial t :description "" :author "" :license "Specify license here" :components ((:module jetty :serial t :components ((:mvn "org.eclipse.jetty/jetty-server/8.1.8.v20121106") (:mvn "org.freemarker/freemarker/2.3.19"))) (:module source :pathname "" :serial t :components ((:file "package") (:file "example")) :depends-on (:jetty)))) The bug is someplace in abcl-asdf:resolve ... didnt figure out where, i just used abcl-asdf:resolve-dependencies ... not sure why you want resolving code in 2 places anyway :).
