[rules-users] Ant build script and XLS Decision Tables failing

Has anyone been able to compile an XLS decision table into a package via an Ant build script? I've scouring the documentation on the Drools Ant Compiler Task (what little I could find) and I can't find any documentation on hw to pass configuration into the ant task for things such as compiling XLS decision tables. Without a configuration entry, when I try and run the build script referencing an excel file, it fails with the following error: Buildfile: C:\Documents and Settings\Adam\workspace\RivaDroolsExperiment\build-5.1.xml compileArtifacts: BUILD FAILED C:\Documents and Settings\Adam\workspace\RivaDroolsExperiment\build-5.1.xml:21: RuleBaseTask failed: null --------------- I suspect this message is because the compiler task is failing with a null pointer exception, which it throws when you don't provide it with a configuration file. I am running the build3423-rev29890-20091102-1042 Drools 5.1 Snapshot. The relevant snippet from the build script: <target name="compileArtifacts"> <compiler srcdir="${projectPath}src/main/rules" tofile="${projectPath}target/experiment.pkg" binformat="package" bintype="knowledge" classpathref="model.classpath"> <include name="Sample.xls" /> </compiler> </target> ------------------ Thanks, Adam
