How to use Tomcat custom Ant tasks in Eclipse [message #155648]

I have a working build.xml that uses the Tomcat 5 custom InstallTask. I want to
be able to build the project using Eclipse 2.1.1 on Win2K but I'm having trouble
configuring Eclipse so Ant recognizes the custom task. If I use Preferences >
Ant > Runtime > Classpath and add the jar that contains the task definition
(catalina-ant.jar), the build fails with the message "taskdef class
org.apache.catalina.ant.InstallTask cannot be found". If I then use Preferences
> Ant > Runtime > Tasks and define a task that references the Tomcat jar file,
I get the error "java.lang.NoClassDefFoundError: org/apache/tools/ant/Task".
ant.jar is included in the Runtime classpath.

How do I configure Eclipse so build.xml can use custom tasks?

Thanks,
Mike

Solution: add classpath (or classpathref) to taskdefs for Tomcat tasks; e.g.,

<path id="tomcat.tasks.classpath"
path="${jwsdp.home}/server/lib/catalina-ant.jar" />

<taskdef name="install"
classname="org.apache.catalina.ant.InstallTask"
classpathref="tomcat.tasks.classpath" />
