How to Build/Clean a RFT project from command Line

Use these commands to compile (build) and run an individual script called "Script1":

set RFT_PROJECT_LOCATION="C:\Path_to_root_of_project"

"%IBM_RATIONAL_RFT_ECLIPSE_DIR%\jdk\jre\bin\java" -classpath "%IBM_RATIONAL_RFT_INSTALL_DIR%\rational_ft.jar" com.rational.test.ft.rational_ft -datastore %RFT_PROJECT_LOCATION% -compile Script1

"%IBM_RATIONAL_RFT_ECLIPSE_DIR%\jdk\jre\bin\java" -classpath "%IBM_RATIONAL_RFT_INSTALL_DIR%\rational_ft.jar" com.rational.test.ft.rational_ft -datastore %RFT_PROJECT_LOCATION% -playback Script1 -log Script1_log

Or you can combine the two commands into one:

set RFT_PROJECT_LOCATION="C:\Path_to_root_of_project"

"%IBM_RATIONAL_RFT_ECLIPSE_DIR%\jdk\jre\bin\java" -classpath "%IBM_RATIONAL_RFT_INSTALL_DIR%\rational_ft.jar" com.rational.test.ft.rational_ft -datastore %RFT_PROJECT_LOCATION% -compile Script1 -playback -log Script1_log
