Subject [jira] Updated: (MRESOURCES-39) Filtering fails for command line properties
Date Fri, 22 Feb 2008 21:00:29 GMT


Paul Gier updated MRESOURCES-39:

    Attachment: maven-resources-plugin-prop-filtering-r630241.patch

The problem seems to be that the resources plugin first adds all the system properties to
it's properties object, then adds properties from project.getProperties().  So the project
properties override the system properties.

The patch reverses this order, and changes one test case to reflect this change.  The only
problem I see is if you wanted to override some default system property (for example "user.home")
in your pom, you wouldn't be able to do this anymore.  I didn't find any easy way to get just
the command line props from within the plugin, but if this was possible it would probably
be a better solution.

values passed to filters.
> I have attached a sample project that defines a property in the pom.xml called 'filtered'
  This property is used as a filter in the file in src/main/filtered/
 I have also included a test that gets passed the filtered property as a System property via
the surefire plugin.  It then loaded the file and tests to ensure the
filters match.
