I am attempting to install software onto my Debian Lenny server. Specifically, Capture-HPC. I have setup VMWare server, along with all the prerequisites. When I go to run ant in the directory, i get the following error:

[taskdef] Could not load definitions from resource net/sf/antcontrib/antcontrib.properties. It could not be found.

Anyone have any ideas what is causing this? Details about my ant installation follow:

Apache Ant version 1.7.0 compiled on April 29 2008
Buildfile: build.xml
Detected Java version: 1.6 in: /usr/lib/jvm/java-6-sun-1.6.0.20/jre

And the build.xml file . . .

  • After installing antcontrib you should use for referencing in your build scripts as net/sf/antcontrib/antcontrib.properties contains only tasks for ant versions before Ant 1.6.x – Rebse Feb 07 '12 at 21:22

This error message indicates that you are attempting to load a non-core task, but the resource which further defines the task is not present (or not where expected).

See installation instructions here.

You can either

  1. find/download the ant-contrib jar and put it into your ant installation (as per option 1 in the link above); or
  2. Modify your ant file (as per option 2 in the link above) to include the ant-contrib jar in a nested classpath.

  • Updated. Do you have the ant-contrib jar? – Synesso Oct 25 '10 at 03:51
  • Where would I look for this? I've downloaded ant-contrib, but can't seem to find it in the downloaded files. I'm not well versed with ant. – Julio Oct 25 '10 at 04:05

    You have downloaded ant-contrib-1.0b3-bin.zip? Inside you will find ant-contrib-1.0b3.jar. Ignore the rest of the files. Put the jar file in the lib directory inside your ant installation and try again. – Synesso Oct 25 '10 at 04:09
  • You were right. Needed to move ant-contrib-{version}.jar into my lib/ – Julio Oct 26 '10 at 04:14
