ANT is failing to find org.dbunit.ant.DbUnitTask

So I'm writing a ant build file to run some tests, and 开发者_开发百科I use the following line without any issue for MXUnit:

<taskdef name="mxunittask" classname="org.mxunit.ant.MXUnitAntTask" classpath="../mxunit/ant/lib/mxunit-ant.jar"/>

But when I download dbunit-2.4.8.jar from http://sourceforge.net/projects/dbunit/files/ and put it in the same directory as mxunit-ant.jar, then added the following line to the ANT build file:

<taskdef name="dbunit" classname="org.dbunit.ant.DbUnitTask" classpath="../mxunit/ant/lib/dbunit-2.4.8.jar"/>

For which I see a warning in Eclipse that says:

taskdef A class needed by class org.dbunit.ant.DbUnitTask cannot be found: org/slf4j/LoggerFactory

When I extract the jar file it does have the org.dbunit.ant.DbUnitTask class.. so I'm very confused as to what ANT is complaining about.. any idea what the issue is?

It looks like you need to make sure all the dependencies of DbUnit are satisfied, as well as installing the dbunit-2.4.8.jar.

The specific error you quote with class org/slf4j/LoggerFactory not being found suggests that you don't have the SLF4J classes needed. (Probably the latest version of slf4j-api.jar is needed there.)
