For an SVN managed project, a tag is a read-only copy that records the current state of the project at the point of time the tag is created.
When working in a tag, you can make changes to your project items, but you will be unable to permanently save your changes to a Job unless you copy the Job to a branch or the trunk. For how to copy a Job to a branch, see How to copy a Job to a branch.
You can create a tag for a project either in Talend Studio or in Talend Administration Center.
To create a tag for a project from the trunk in Talend Studio, do the following:
Close all open editors in the design workspace before trying to create a tag. Otherwise, a warning message will appear prompting you to close all open editors.
Open the remote project for which you want to create a tag.
Click the icon at the upper right corner of the Repository tree view to open the [Branch management] dialog box.
Click the Create a tag button, and in the next dialog box select trunk from the tag's source list, enter a tag name, and click OK.
In the [Confirm] dialog box, click OK to confirm your tag creation.
Creating a tag may take some time. When done, the tag you created will appear on the tags list in the [Branch management] dialog box and you can switch to it by following the steps in How to switch between branches.
For how to create a tag in Talend Administration Center, see Talend Administration Center User Guide.
