Hello here is the source of an example how we (my friend and Apple-Fan Michael and myself) did do it some months ago last year. The purpose was to collect log4j configuration from various locations into one file.
The idea is to include the dtd and the xsl script in the jar, to be automatically used, when nothing else is configured. If I understand the original problem correctly, this is more or less want you want. As you can see in the source, we adapted it from Cameron Taggart at the time. Change the package name (or whatever else...) and the import of the AbstractFileScannerMojo (also included). If it is of any value, please let me know any results of your work. Hope this helps Wolfgang ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ package WHATEVER.maven.util; /* * Licensed to the Apache Software Foundation (ASF) under one * or more contributor license agreements.
