Continuous Integration with Enterprise Architect

In the course of the increasingly agile orientation in software development, our customers ask us
again and again whether modelling and agility go well together. Our opinion on this is quite clear
and has also been proven in various studies: Only with properly applied modelling can agile processes be implemented at all in the face of increasing complexity, if you also want to document all regulations and requirements in a comprehensible way. As an example, we want to deal in this text with „Continuous Integration“, which has been state of the art in classical software development for some time. The aim is to continuously compile, test and merge the software product to be developed. In addition, the status of the development is published regularly: internally a stable development status, externally an official release of the software.

When LieberLieber launched its product LemonTree four and a half years ago, its success story was not yet foreseeable. However, as the trends in software and system development continued to intensify, LemonTree 3.0 now opens up completely new possibilities for product line development, use in the supply chain and team-based modelling.

Setting up a Git Repository for the LemonTree EA Addin Git Features

Working with Feature-Branches in a Subversion Environment

While our recommended workflow for utilizing LemonTree is combining it with GitFlow (see here for details: LemonTree and GitFlow), we realize that not everyone has the possibility to switch their entire workflow to utilize it.
