Hi, I am new to ANT and I am facing a few issues when executing a build.xml file. I request your help in resolving this issue. I have set the environment variables - ANT_HOME, JAVA_HOME, PATH, ANT_ARGS, ANT_OPTS. When I execute the build.xml file, below is the output in the console. ************************************************************************ ****************** Buildfile: C:\projects\ADAS-INTRAV25A\implementation\build_config\build.xml [taskdef] Could not load definitions from resource net/sf/antcontrib/antcontrib.properties. It could not be found. [get] Getting: :8080/build.xml [get] To: C:\Documents and Settings\raora\.ant\build.xml [get] Not modified - so not downloaded [loadfile] C:\BEA1034\oepe_11gR1PS3\plugins\org.apache.ant_1.7.1.v20100518-1145\etc \tiaa.version.txt doesn't exist BUILD FAILED C:\projects\ADAS-INTRAV25A\implementation\build_config\build.xml:5: The following error occurred while executing this line: C:\Documents and Settings\raora\.ant\build.xml:10: Problem: failed to create task or type if Cause: The name is undefined. Action: Check the spelling. Action: Check that any custom tasks/types have been declared. Action: Check that any / declarations have taken place. Total time: 110 milliseconds ************************************************************************ ***** When I execute the build file "C:\projects\ADAS-INTRAV25A\implementation\build_config\build.xml", it has a logic to import another build file: "C:\Documents and Settings\raora\.ant\build.xml". I personally don't know the reason behind this as it is an existing code base. I read in multiple posts online which suggested downloading the antcontrib.jar file and placing it in the ANT lib folder. I verified it and it is already present. So I am not sure how to proceed here. Below is the content of C:\projects\ADAS-INTRAV25A\implementation\build_config\build.xml Please let me know if you need more details. ************************************************************************* This e-mail may contain confidential or privileged information.
