Subject Cannot use antlib:... with CppTasks!?!?!
Date Tue, 21 Oct 2003 16:54:57 GMT
I'm a little baffled... I've added an antlib.xml to CppTasks.jar, which is
in ant/lib (as is AntContrib.jar). I've declared the
xmlns:cpp="antlib:net.nf.antcontrib.cpptasks" shortcut on the <project>
top-level element, and still it cannot find the <cpp:compiler> datatype.

I originally used the cc namespace prefix instead of cpp, and thought it
might somehow conflict with the <cc> task define, but that's not it, as cpp
doesn't work either as a prefix.

After having used AntLib successfully with my own tasks, and AntContrib's,
I'm not really sure what could be wrong here! Could it be the fact that the
resources loaded from the AntLib are in the default package? Bug?

Help please. I've include all the relevant info I could think off. I hope
it's not too much... --DD

P:\com_lgc\10.0.7\gocad\T-Surf\Filters>build -f cpptasks.xml
Buildfile: cpptasks.xml

BUILD FAILED
P:\com_lgc\10.0.7\gocad\T-Surf\Filters\cpptasks.xml:7: Could not create task
or type of type: antlib
:net.nf.antcontrib.cpptasks:compiler.

Ant could not find the task or a class this task relies upon.

This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
 - You have misspelt 'antlib:net.nf.antcontrib.cpptasks:compiler'.
   Fix: check your spelling.
 - The task needs an external JAR file to execute
   and this is not found at the right place in the classpath.
   Fix: check the documentation for dependencies.
   Fix: declare the task.
 - The task is an Ant optional task and optional.jar is absent
   Fix: look for optional.jar in ANT_HOME/lib, download if needed
 - The task was not built into optional.jar as dependent
   libraries were not found at build time.
   Fix: look in the JAR to verify, then rebuild with the needed
   libraries, or download a release version from apache.org
 - The build file was written for a later version of Ant
   Fix: upgrade to at least the latest release version of Ant
 - The task is not an Ant core or optional task
   and needs to be declared using <taskdef>.

Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath

Please neither file bug reports on this problem, nor email the
Ant mailing lists, until all of these causes have been explored,
as this is not an Ant bug.
