Can't render component diagram with PlantUML in IntelliJ

Question

I am trying to create a component diagram using the PlantUML plugin for IntelliJ. I have installed the plugin and worked with it before. However, when I try to render a component diagram, I get an error:

Cannot find Graphviz

I've also checked with other diagrams and a sequence diagram is still working just fine.

What is the problem here?

Answer 1

Sequence diagrams and activity diagrams work out of the box.

For other types of diagrams, you need to have Graphviz installed (version > 2.26.3).

1. If you don't have Graphviz installed - just install it.
2. If you have it installed but its version is improper - reinstall it.
3. If you have it installed in proper version but location is other than default - point to that location. You can manage that either by specifying env variable GRAPHVIZ_DOT containing a path to Graphviz executable or pointing it out directly from IntelliJ's PlantUML plugin settings.

Here, you can read more on how to install Graphviz to get along with PlantUML.

Btw. I solved the same problem by simply typing sudo apt-get install graphviz in my console - maybe would work for you as well.
