Description Matt Wildig 2008-10-29 08:30:43 UTC 
Not sure if this counts as a bug, but I thought it needs mentioning.

The "resources" task described in antlib.xml in catalina-ant.jar conflicts with the resources element introduced in ant 1.7.

This results in ant reporting the message "Trying to override old definition of datatype resources", which may be the only effect if you're not using the ant resources (http://ant.apache.org/manual/CoreTypes/resources.html#collection).

It does have the potential to cause existing builds using these resources collections to fail if you then add the tomcat tasks using the antlib.xml.
Comment 1 Matt Wildig 2008-10-29 12:59:07 UTC 
A little bit of thought and research into this and I realise the solution is of course to use ants namespace support. Perhaps all that's needed is a note in the documentation so people don't get caught out by this.

Thanks for the report. this has been fixed in trunk and 6.0.x and will be in 6.0.19 onwards.
Comment 3 Jonathan Horowitz 2017-04-20 19:59:15 UTC 
This is still happening for me with Ant 1.8 and Tomcat 8.5.11.

I went through the ASF SVN revisions around that time, and could not find anything regarding this issue.

Perhaps the fix was lost on a local dev machine and never committed?
Comment 4 Mark Thomas 2017-04-20 20:23:03 UTC 
The minimum Ant version to build 8.5.x is 1.9.5 as documented in BUILDING.txt in the root of the directory.

Comment #3 is therefore INVALID but I am restoring the fix status for this issue.
Comment 5 Mark Thomas 2017-04-20 20:25:41 UTC 
Ignore the 1.9.5 comment but the INVALID aspect stands. The need to use a namespace is documented in the Manager HowTo.
