After the download is complete, drag the downloaded .jar file to an open instance of Astah. A pop-up will appear asking you to confirm installation. Choose [Yes]. If the pop-up below opens, restart Astah.
If you see [Simple SVN operation] under [Tools], the installation is complete.
How to Use
Make sure you have a Subversion client, and add your .asta files to the working copy managed by the client.
Launch Astah and open the .asta file.
Go to [Tools] – [Simple SVN operation] – [Configuration] and enter the information for the Subversion repository.
After modifying the models, go to [Tools] – [Simple SVN operation] – [Diff between the base revision], check the changes, and click [Commit].
If the repository has a newer revision, click [Update] to update all models in the open file. If the working copy also has changes, the [Merge] dialog opens. Choose how you want to merge.
Limitations
You can save only one repository URL, user name, and password.
Showing history and checking out are not supported.
You need an SVN client (for example, TortoiseSVN) to use this plugin.
Tested only with Subversion 1.7.
This plugin works with .asta files that are:
committed to and checked out from the Subversion repository, or
stored in the SVN working directory together with the committed files.
