Subject RE: Cannot use antlib:... with CppTasks!?!?!
Date Tue, 21 Oct 2003 18:26:24 GMT
I've turn around the pb for now by using the good old tasks/types properties
resource, setting the URI explicitly:

    <taskdef resource="cpptasks.tasks"
             uri="antlib:net.nf.antcontrib.cpptasks" />
    <typedef resource="cpptasks.types"
             uri="antlib:net.nf.antcontrib.cpptasks" />

I've also figured out that my antlib.xml is also not working with
Ant-Contrib, as I thought it did (I use the same work around).

I'm missing something here. Any help would be appreciated. Thanks, --DD

PS: Peter, from the stack in UE, looks like you are swallowing the real
cause of the exception, instead of nesting it in the BuildException. That
would help troubleshoot problems like the one I'm seeing.
