Darren Yin commented on HIVE-3377: ---------------------------------- The problem likely comes from ant-contrib not being loaded by ant when ant model-jar is run. If you want it to run without deleting that line, you may be able to run something like ant -lib /usr/share/java model-jar assuming that you have the ant-contrib jar sitting in /usr/share/java. > ant model-jar command fails in metastore > ---------------------------------------- > > Key: HIVE-3377 > URL: https://issues.apache.org/jira/browse/HIVE-3377 > Project: Hive > Issue Type: Bug > Components: Metastore > Affects Versions: 0.10.0 > Reporter: Vandana Ayyalasomayajula > Priority: Minor > Labels: build > > Running "ant model-jar" command to set up eclipse dev environment from the > following wiki: > https://cwiki.apache.org/Hive/gettingstarted-eclipsesetup.html > fails with the following message: > BUILD FAILED > **/workspace/hive-trunk/metastore/build.xml:22: The following error occurred > while executing this line: > **/workspace/hive-trunk/build-common.xml:112: Problem: failed to create task > or type osfamily > Cause: The name is undefined. > Action: Check the spelling. > Action: Check that any custom tasks/types have been declared. > Action: Check that any <presetdef>/<macrodef> declarations have taken place. -- This message is automatically generated by JIRA.
