The diff from the previous message had several problems.
After fixing the problems one by one I now have working version - see svn.diff attached (can't submit it as a ticket, because don't know how to login into the new ABCL Trac).
I must say I now feel how convenient :mvn ASDEF componets are. I just do (ql:quickload :my-system) and it automatically installs and loads all the Lisp and Java dependencies (ApachePOI takes 8 .jar files to install).
As for keeping compatibility with old maven. Various approaches possible here. I would suggest to commit my patch and be compatible with the latest maven version. If necessary, record a separate ticket to generalize/conditionalize the :mvn components implementation to make it compatible with both old and new maven.

P.S. Maven 3.1.0 release notes, where they describe Aether API change: http://maven.apache.org/docs/3.1.0/release-notes.html

I think I found the reason.
I am using the latest maven 3.1.0. The Aether API has moved to another packages: org.eclipse.aether.*
I have changed contrib/abcl-asdf/maven-embedder.lisp file to use new java class names (as in the addached svn.diff), and the error seems gone.
I continue to work on the Excel improt, will here report if find new information.
Best regards,

Hello.
I need to import data from Excel, and following Hans Hübner's article for how to do this with ABCL: http://netzhansa.blogspot.com/2013/03/dealing-with-excel-files-from-common.h...
The Hans' code depends on Apache POI library.
I saw that ABCL comes from abcl-asdf contrib, which extends ASDF by adding a :mnv component, so that we can specify :mvn artifact as a dependency of our ASDF system. I would like to use this facility to automatically install the POI .jar files.
I created an .asdf file with this content:
(defsystem :excel-s :defsystem-depends-on (:abcl-asdf) :version "0.1.0" :encoding :utf-8 :components ((:mvn "org.apache.poi/poi-ooxml/3.9")))
Then I invoke ABCL: C:\Users\anton\projects\abcl\abcl.bat --batch --eval "(require :abcl-contrib") --eval "(pushnew "./" asdf:*central-registry* :test #'equal)" --eval "(ql:quickload :excel-s)"
It fails with exception: java.lang.ClassNotFoundException: aether.util.artifact.DefaultArtifact This exception is throw by abcl-asdf::resolve-dependencies function, defined in the contrib/abcl-asdf/maven-embedder.lisp.
Maven is installed on my machine, including the /lib/ directory containing the Aether API jars.
I performed some investigation and tried to ensure the Aether .jars are added to classpath:
(abcl-asdf::init) (let ((*default-pathname-defaults* abcl-asdf::*mvn-libs-directory*)) (dolist (jar-pathname (or (directory "**/*.jar") (error "no jars found in ~S - expected Apache Maven /libs/ directory ~ installation there" (merge-pathnames abcl-asdf::*mvn-libs-directory*)))) (java:add-to-classpath (namestring jar-pathname))))
Still I have the same error - class aether.util.artifact.DefaultArtifact not found.
Is the way I am trying to install java libs expected to work, and how to find the problem?
Best regards, - Anton
