plantuml - generate UML diagrams from files and view them in Eclipse

The plantuml library implements a DSL and renderer for many UML diagrams (class, sequence, objects, states, activities, …). See for more info about the DSL and renderer.

This project integrates plantuml’s functionality into Eclipse, by means of a view that shows a diagram for the currently active editor. The rendered diagram is typically based on explicit DSL code embedded in the editor, or generated from the content of the editor.

We currently support generating diagrams for

There’s also experimental support for generating a diagram for all the Java classes in a Java project (or within one or more Java packages).

Diagram generation is handled by (implementations of) an extension point, so you can customize the process of generating a diagram for other file types or editor content.

We use Issues for issue tracking, so head there concerning bugs or suggest features (check if they already exist before adding).

However, we have now (September 2021) started using Discussions, so please consider it, before use Issues, as the dialog may resolve the issue before it is even raised! Of course, you can also ask questions about how to use PlantUML, tell us about how you use it, comment on where the plug-in should be heading, etc.


We use github pages @ as the update site URL, in the Help > Install New Software… dialog.

Main plugins (net.sourceforge.plantuml.)


Notable features in recent releases, details are found in releases. Note that the version numbers of the plantuml.lib plugin are a bit special, since they use the version of the included plantuml.jar
