pom-parser

I’ve been trying to use pom-parser.el with maven 2.0.8. It seems that the maven.dep.cpFile property isn’t working. I checked the docs for the plugin, and it says that parameter is deprecated, replaced with outputFile.

http://maven.apache.org/plugins/maven-dependency-plugin/build-classpath-mojo.html#cpFile

So I tried the outputFile and that didn’t work either, for me output always goes to stdout, never to the file.

I’m using the latest pom-parser.el from http://svn.grumblesmurf.org/svn/pom-el/trunk/pom-parser.el , GNU Emacs 23.0.60.1, and maven 2.0.8

I took a shot at parsing the output to capture the classpath. I was thinking that this function,or a better one ;-) could parse the output of the two goals( effective pom and the dependency classpath) instead of two temp files in ‘pom-parse-pom’.

I also found that in my prj.el I needed to specify *pom-node*:

(jde-project-file-version "1.0")
(jde-set-variables
'(jde-compile-option-command-line-args
(quote ("-Xlint:all" "-Xlint:-serial"))))
(require 'pom-parser)
  (with-pom ()
  (pom-set-jde-variables *pom-node*))
