The Question
I'm trying to use the Force.com Migration Tool (a custom ant library) on a linux box and can't for the life of me figure out how to get ant to see that library. What am I doing wrong?
The Error Message
BUILD FAILED
/home/ec2-user/ant/ucp/build.xml:48: Problem: failed to create
task or type antlib:com.salesforce:retrieve
Cause: The name is undefined.
The Background
I installed ant using yum install ant and then I dropped the Force.com Migration Tool (ant-salesforce.jar) into /usr/share/ant/lib. I'm able to see this library when I run ant -diagnostics, but none of the tasks for that library (should be seeing deploy, retrieve, etc.). I've uploaded a gist with the full output from ant -diagnostics.

ANT_HOME/lib jar listing
-------------------------------------------
ant.home: /usr/share/ant
ant-bootstrap.jar (19837 bytes)
ant-salesforce.jar (3293054 bytes)
ant.jar (1942059 bytes)
ant-launcher.jar (18418 bytes)
After lots of googling and manual reading I tried the following to no avail (NB: the above diagnostics is without any of the below changes). I know I'm missing something obvious :(
- Setting $ANT_HOME
export ANT_HOME=/usr/share/ant - Fiddling with permissions
chmod +x /usr/share/ant/lib/salesforce-jar - Fiddling with groups
chown root:root /usr/share/ant/lib/salesforce-jar - Passing in class with -lib
ant -lib /usr/share/ant/lib/salesforce-jar retrieve ... - Passing in lib folder with -lib
ant -lib /usr/share/ant/lib retrieve ... - Adding $ANT_HOME to $PATH
export PATH=$PATH:$ANT_HOME/bin
回答1:
How about keeping ant-salesforce.jar under /home/ec2-user/ant/ucp and then change the taskdef element to look like this:
<taskdef resource="com/salesforce/antlib.xml" classpath="ant-salesforce.jar" />
Run your build again and see if things look better. Having the JAR in the same folder as build.xml will help you eliminate issues with permissions.

Based on @smooth_reggae's answer was able to get things working while keeping ant-salesforce.jar in the default ant lib directory. Seems like this should already be happening, but oh-well.
<taskdef resource="com/salesforce/antlib.xml"
classPath="${ant.library.dir}/ant-salesforce.jar"
uri="antlib:com.salesforce"/>
