SCM stands for Source Code Management is an integral part of any development project in the current IT world. It is very critical to manage source code in an efficient way. There are several SCM tools which are available. Some ADVANTAGES of using SCM:

1. Backups: Always accept that your PC is going to be sucked into a monstrosity dark opening at any second and WORK to limit the misfortune from that. Source control enables you to effortlessly push finished work to a remote host so LITTLE work is lost with a solitary PC.
2. Record of work: On numerous ventures, there's intermittently when you need to return the code to a past state to perceive how something was done, if a bug was available, or work out why the present code is broken. Source control makes this simple.
3. Arrangement: Having source control enables you to robotize fabricates and organizations. No one ought to ftp records around any longer as that is inclined to human blunder.
4. Forming: It's anything but difficult to swap between renditions of your code, giving you a chance to switch between fixing a little bug UNDERWAY and thoroughly reworking your key usefulness.
5. Simple venture setup: As a task's source code can likewise incorporate arrangement contents, introduce records, and so forth… at that POINT setting up an undertaking can be as simple as cloning the storehouse and running a few contents to set up a domain that is indistinguishable from every single other designer.

Jenkins underpins AccuRev, CVS, Subversion, Git, Mercurial, Perforce, ClearCase and RTC. For every one of them exists a module and as you likely definitely know, Jenkins isn't constrained to just that rundown, anybody can make an SCM module for different choices on the off chance that they need to.

Here is the connection to the modules: 

• ClearCase: https://wiki.jenkins-ci.org/display/JENKINS/ClearCase+Plugin
