While building a tld using $ mvn taglib:tldgenerate I get the attached error, I also attached the current project layout. I configured the my pom.xml to do the following: <build> <plugins> <plugin> <groupId>net.sourceforge.maven-taglib</groupId> <artifactId>maven-taglib-plugin</artifactId> <configuration> <taglibs> <taglib> <uri>http://www.peppermind.de/2010/taglib</uri> <shortName>tags</shortName> <outputname>testtaglib</outputname> <functionClasses> <functionClass>de.peppermind.util.taglib.TestTag</functionClass> </functionClasses> </taglib> </taglibs> </configuration> Regs, Rob
