[PATCH] Is junit-3.8.1.jar optional for Velocity as specified in jar dependencies?

When i navigate to the build directory in Velocity 1.6.2 and invoke "ant" then the below error is got:
Could not create task or type of type: junit. lib\test.
Ant could not find the task or a class this task relies upon.
Refer screenshot

I deleted the junit-3.8.1.jar file from bin\test-lib as it was specified to be optional, but it gets created automatically.

Do we need to remove the dependency on this junit-3.8.1.jar manually?
