Description

The maximum length of the DOS command string is 8191 characters (in Windows latest versions http://support.microsoft.com/kb/830473). Following entries in the “build-common.xml” are adding lot of duplicate JAR entries to the “test.classpath” and it exceeds the max character limit on windows very easily.

<!-- Include build/dist/lib on the classpath before Ivy and exclude hive jars from Ivy to make sure we get the local changes when we test Hive -->
<fileset dir="${build.dir.hive}/dist/lib" includes=".jar" erroronmissingdir="false" excludes="/hive_contrib.jar,*/hive-contrib.jar,*/lib.jar"/>
<fileset dir="${hive.root}/build/ivy/lib/test" includes=".jar" erroronmissingdir="false" excludes="/hive_.jar,*/hive-.jar"/>
<fileset dir="${hive.root}/build/ivy/lib/default" includes=".jar" erroronmissingdir="false" excludes="/hive_.jar,*/hive-.jar" />
<fileset dir="${hive.root}/testlibs" includes="*.jar"/>

Proposed solution (workaround)–
1)Include all JARs from dist\lib excluding "*/hive_contrib.jar,*/hive-contrib.jar,*/lib.jar"
2)Select the specific jars (missing jars) from test/other folders, (that includes Hadoop-*.jar files)

Thanks
