ERROR: Error during "install" phase:
  ERROR: exec returned: 1
    exec returned: 1
--------------------------------------------------------------------------------------------------------

Unfortunately, Verbose output of the installation doesnot tell you anything about the exact problem...

So, to handle this error we need to check the ANT log files under following directory

/var/ibm/InstallationManager/logs/ant/

Excerpt of the log file.....
----------------------------------------------------------------------------------------------------------------------
 [exec] CWPZT0854E: An I/O problem has occurred, please check the exception to determine the problem.
     [exec] java.io.IOException: There is not enough space in the file system.
----------------------------------------------------------------------------------------------------------------------

So now you know the problem. Simply increase the file system (mostly it would be /var as that is the place where ICCT will get installed). I increased it by 2GB and after that everything went fine......
