Ivy ibiblio resolver chokes on variables while checking descriptor consistency
------------------------------------------------------------------------------

                 Key: IVY-818
                 URL: https://issues.apache.org/jira/browse/IVY-818
             Project: Ivy
          Issue Type: Bug
          Components: Maven Compatibility
    Affects Versions: 2.0-RC1
         Environment: Ubuntu 8.04, ivy svn rev: 657553
            Reporter: Robert Newson



The ibiblio resolver in trunk has a new facility for parsing maven-metadata.xml 
in order to find the latest snapshots. Unfortunately it doesn't work if the 
version numbers in the poms are variables, that is, our pom's have 
${subproject-version} in them.

When encountering these, Ivy throws this;

java.text.ParseException: inconsistent module descriptor file found in 
'http://mvn.mycompany.com/maven2/<removed>/1.2.0-RQA2-20080518.055623-736.pom': 
bad revision: expected='1.2.0-RQA2-SNAPSHOT' found='${subproject-version}';

It seems Ivy verifies that the pom matches the metadata file, laudable in 
itself, but doesn't know that ${subproject-version} expands to the expected 
value. Setting that as a property did not help.
