Ans 1 : Ant should be installed on the BF agent.
Ans 3 : When you install the buildtoolkit on the BF agent it will create a directory structure something like this /jazz/buildsystem/buildtoolkit
under /opt/IBM
.
Ans 4 :From the eclipse RTC client I have to schedule the build on a time basis(e.g every 60 mins) and after this it will check in every 60 mins for the new code checked in and trigger the build if there is any new code checked in last 60 mins.
Build Forge is not that smart that it can initiate the build as soon as somecode is checked in ,contrary it waits on the scheduled time to initiate the build.
