Hello,
The fact that it is failing in the main thread. It's failing while loading up and launching ant. This tells me (my opinion) that ANT is not set properly. I see you set ANT_HOME to where you decompressed the ANT files? That may be correct, but have you tried adding
${ANT_HOME}/bin
(Unix) or
%ANT_HOME%/bin
(Windows) into your PATH?
It's not able to find the class org.apache.tools.ant.launch.Launcher which resides in the ant-launcher.jar. You Now, it's very unlikely that the ant-launcher.jar is missing a class. But you could expand it and check if the class if there. If the class is there, it's the classpath that needs adjusting.
Could try ant --execdebug and see what the output is. Although, I have never used it.
Hope this helps.

Hi Ryan,
I could resolve this issue, Thanks for suggestion. I haven't included PATH, and I am working with System z , So i just manually searched on the .jar file correct location and then it had lib and bin. So gave that path as ANT_HOME, now it is proceeding with compile. Thanks, Viji |
