You can configure Jenkins to access the sources you store in a source control system, of which there are many types. The simplest
               way to do this is to use a file system watcher which triggers an action when a change occurs in the source control repository.
               
               	 
            
 
            	 
            To enable Jenkins to access the source control, install a required plugin: 
               	 
            
 
            	 
             
               		
               -  In the Jenkins Home page, click 
                  		  Manage Jenkins > Manage Plugins, and then click the 
                  		  Available tab. 
                  		
               
-  Locate 
                  		  File system SCM, and then install the required plugin by enabling the check box and clicking 
                  		  Install. 
                  		
               
-  Restart Jenkins (you can select 
                  		  Ctrl+C in the command window that is running Jenkins and then start Jenkins again). 
                  		
               
The following example shows how to configure your project to access the sources from Subversion: 
               	 
            
 
            	 
             
               		
               -  Navigate to the project's configuration area. 
                  		
               
- Under 
                  		  Source Code Management, click 
                  		  Subversion. 
                  		
               
-  In the 
                  		  Repository URL area, specify the URL path of the source control that you want to work with. 
                  		
               
- Specify the credentials and a local check-out directory as required. 
                  		
               
-  Click 
                  		  Apply to save the configuration. 
                  		  
                  You have now created a source configuration for your project, but you also need to change the 
                     			 Build Triggers section to tell Jenkins to monitor that location.
