Not able to compile from the svn source

Hi all I have checked out the source from object web and try to compile it but without any success. error message is as follow: BILD FAILED /usr/local/src/xwiki/build.xml:127: taskdef A class needed by class org.apache.cactus.integration.ant.CactusTask cannot be found: junit/framework/Test I have looked into build.xml and at line 127, the following was found: <!-- Define the Cactus tasks --> <taskdef resource="cactus.tasks"> <classpath> <pathelement location="${lib.dir}/cactus-1.6dev.jar"/> <pathelement location="${lib.dir}/cactus-ant-1.5.jar"/> <pathelement location="${lib.dir}/commons-httpclient-2.0-rc2.jar"/> <pathelement location="${lib.dir}/commons-logging.jar"/> <pathelement location="${lib.dir}/aspectjrt-1.1.1.jar"/> </classpath> </taskdef> Notice that all the above mentioned library except commons-httpclient-2.0-rc2.jar were found in the lib directory. commons-httpclient-2.0.1.jar were found in lib directory instead. I have tried to change the above to commons-httpclient-2.0-1.jar but still got the above message. What have I missed. Any help is appreciated. Patrick Lee
