Maven Ant Tasks

[Abder-Rahman Ali]

I have a build file as shown below (AFTER THE ERROR).

When I try to run it I get the following error:


Buildfile: build.xml

BUILD FAILED

How can I deal with this error?

Thanks.

We have a separate forum for maven. I will move this topic there.

What installation method did you use to install maven-ant-tasks-2.0.9.jar? http://maven.apache.org/ant-tasks/installation.html gives three options. If you did not copy the JAR to the Ant lib directory, you might try doing that.

Thank you for your reply. I actually did include the maven-ant-tasks-2.0.9.jar in the Ant "lib" directory".
