Using a function as build-step?

Hi,

while packaging some java apache common packages, I found myself adding
some build steps over and over again, like this one:

         (replace 'install
           (lambda* (#:key outputs #:allow-other-keys)
             (let ((share (string-append (assoc-ref outputs "out")
                                         "/share/java")))
               (for-each (λ (f) (install-file f share))
                         (find-files "target" "\\.jar$")))))

Now I tried replacing this by a simple line like

         (add-after 'install 'install-javadocs install-javadocs)

and of course some function:

  (define* (install-javadoc #:key outputs #:allow-other-keys)
    (let ((docs (string-append (assoc-ref outputs "doc")
                               "/share/doc/" ,name "-" ,version "/")))
      (mkdir-p docs)
      (copy-recursively "target/apidocs" docs)
      ))

I did not manage this - not even if not using "name" and "version" and
not using any function parameters.

What is the correct code?
