VCS Integration

LemonTree can be seamlessly integrated into existing versioning systems, such as Subversion, Git or PTC. This enables the centrally and automatic management of model versions. It also enables parallel editing of models in a team, as has for years been a common approach when editing source code. LemonTree for Enterprise Architect is referred to as a Diff & Merge Tool for VCSs as soon as a model is checked into the central repository.

The sub-pages of this page detail the process of integrating LemonTree into a number of existing version control systems.

The help pages are split based on the version of LemonTree you are using. LemonTree 2.6.1 introduces the LemonTree Starter -  an addiitonal executable providing additional features for VCS integration. Therefore, the described VCS integration setups for LemonTree Version 2.6.1 or newer describe how to utilize the LemonTree Starter. You still have the option of invoking LemonTree directly as with previous versions, however.
