Exclude second Ant JAR from classpath in hdfs builds
----------------------------------------------------
Key: HDFS-798
URL: https://issues.apache.org/jira/browse/HDFS-798
Project: Hadoop HDFS
Issue Type: Improvement
Components: build
Affects Versions: 0.22.0
Reporter: Steve Loughran
Priority: Minor
I've no evidence that this is a problem, but I have known it to be in different
projects:
{code}
[junit] WARNING: multiple versions of ant detected in path for junit
[junit]
jar:file:/Users/slo/Java/Apache/ant/lib/ant.jar!/org/apache/tools/ant/Project.class
[junit] and
jar:file:/Users/slo/.ivy2/cache/ant/ant/jars/ant-1.6.5.jar!/org/apache/tools/ant/Project.class
{code}
Somehow Ivy needs to be set up to skip pulling in an old version of Ant in the
build -both paranamer-ant and jsp-2.1 declare a dependency on it. If both tools
are only ever run under Ant, the ivy.xml file could exclude it, the build file
just has to make sure that Ant's own classpath gets passed down.
