    [ https://issues.apache.org/jira/browse/HADOOP-6468?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12863771#action_12863771 ] 

Steve Loughran commented on HADOOP-6468:
----------------------------------------

adding some extra diagnostics to the build fixes the location
{code}
    <whichresource class="org.objectweb.asm.ClassWriter"
      property="asm.location"
      classpathref="classpath" />
    <echo level="verbose" >asm.location=${asm.location}</echo>
{code}
this results in 
{code}
[whichresource] Searching for org/objectweb/asm/ClassWriter.class
     [echo] asm.location=jar:file:/home/slo/.ivy2/cache/asm/asm/jars/asm-2.2.3.jar!/org/objectweb/asm/ClassWriter.class
{code}
Something is pulling in asm-2.2.3, this looks to be paranamer itself; yet the versions aren't in sync. If you drop asm-3.1 into ANT_HOME/lib the build works. Which implies the 2.2.3 version is the wrong one.

Proposed: 
# insert the diagnostics code into the build.xml file, 
# add an explicit reference to the asm version hadoop needs, ivy will discard the old ones.
