7.This tutorial is intended to explain how to use Subversion to participate in Google Code projects using NetBeans in a Windows environment. (Russian version)Definitions:First, some definitions. Subversion (SVN) is a revision control system used in software development projects. It logs the complete history of a project and can be used to coordinate the efforts of many different developers. Google Code is a project hosting service run by Google. It provides a number of different tools that can help facilitate the design, implementation, and deployment of a software application. NetBeans is an integrated development environment (IDE) supported by Sun Microsystems. Windows is a popular operating system published by Microsoft. This tutorial will specifically focus on Windows XP, although it may be applicable to other versions, as well.Prerequisites:A Google account.Membership in a Google Code project.A computer running Windows, with NetBeans installed.Installing SVN:In order to retrive the latest version of the source code and upload changes, it is necessary to install a Subversion client. There are a number of SVN clients available, but one of the best options for Windows is Tortoise SVN. The installer is located here. After downloading and installing this program, the computer must be restarted.The Google Code Password:One of the most confusing things about Google Code is that users can sign in to the site with their Google Account password, but code checkout requires a Google Code password. (The user name for both of these activities is the same.) Here are the steps for finding an accounts Google Code password:Go to the Google Code project. The URL should be http://.googlecode.com/.Sign in using the Google Account.Click on the Source tab.Click on the Checkout link.Click on the link called googlecode.com password.Write down the password. It will be needed later.Checking Out the Code:It is helpful to establish a file directory structure to organize the project source code. Under My Documents, create a folder called NetBeans. Inside the NetBeans folder, create another folder with the same name as the project. This folder will hold all of the source files for the project. The following steps will check out the source code and download it to the project folder:Use Windows Explorer to enter the project folder.Right-click in the window, and select SVN Checkout... from the list. This brings up the Tortoise SVN checkout dialog.Under URL of repository enter https://dupysoft-tracs.googlecode.com/svn/trunk/Under Checkout directory browse to ...\My Documents\NetBeans\.Click OK.Enter the Google Code user name and password when prompted.The source code should now appear in the project folder. The checkout is complete.Opening the Source Code in NetBeans:Start the NetBeans application. Choose File->New Project...->Java Project with Existing SourcesClick NextUnder Project Name enter the project name.Under Project Folder browse to the NetBeans folder in My Documents.Click NextClick Add Folder... and select the project folder.Click Next and then FinishUpdating the Source Code:Before each editing session, it is a good idea to update the local copy of the source code. This will incorporate all of the checked in changes from all of the developers working on the project. To update the source, simply go to the project folder, right-click, and select SVN Update.Checking In
