I didn’t find any reference to ant on http://www.antlr.org/download.html. The relevant instruction in my build file is: <antlr:antlr3 xmlns:antlr="antlib:org/apache/tools/ant/antlr" target="${srcdir}/ANTLR/${grammar.name}.g"> <classpath path="/home/hendrik/Java/antlr-3.1.1/lib" /> </antlr:antlr3> Where /home/hendrik/Java/antlr-3.1.1/lib contains > ls /home/hendrik/Java/antlr-3.1.1/lib antlr-2.7.7.jar antlr-3.1.1-runtime.jar antlr-3.1.1.jar stringtemplate-3.2.jar I am on openSUSE 11.0. The Ant error message is: BUILD FAILED /home/hendrik/workspace/MonaSearch-own-formulas/build.xml:85: Problem: failed to create task or type antlib:org/apache/tools/ant/antlr:antlr3 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 appears to be an antlib declaration. Action: Check that the implementing library exists in one of: -/usr/local/eclipse/plugins/org.apache.ant_1.7.0.v200803061910/lib -/home/hendrik/.ant/lib -a directory added on the command line with the -lib argument Now I had this before with jUnit, and it didn’t help putting the antlr.jar in any of the mentioned directories. For junit, the solution was to install ant-junit from YaST, but that doesn’t work for antlr, since it installs a task for antlr2. even > ant -lib /home/hendrik/Java/antlr-3.1.1/lib/ antlr doesn’t work.
