[catalog-server] $ cmd.exe /C '"ant.bat -file build.xml install && exit %%ERRORLEVEL%%"'
'ant.bat' is not recognized as an internal or external command, operable program or batch file.
1) The machine which runs Hudson might not have ANT installed on it.
2) If ANT is installed on it then you might not have set the ANT_HOME variable.
3) If ANT_HOME is set, then you might not have set %ANT_HOME%\bin as a part of the system PATH variable.
4) If that is also set, then you may have started your application server (tomcat\hudson) before you performed steps 1-3 so the changes haven't taken effect yet, try restarting it.
5) No good? You may be starting or stopping the tomcat container as a windows service BUT the user under whom the service actually runs may be a different one! This means you need to log that user out and then back-in for him/her to pick up the changes made to the system variables like ANT_HOME or PATH. You can simply reboot your machine if you don't know who that user is or what their password happens to be.
6) No luck? Goto Hudson > Manage Hudson > Configure System > Ant and fill out a value for the ANT_HOME variable and then click Save.
7) Still no luck? Well go to the Job in question and then goto Configure > Build > Invoke Ant > Ant Version and change it from (Default) to the one you configured in the previous step.
