For details, see: http://plantuml.com/graphviz-dot . 37 | 38 | Building 39 | ---- 40 | 41 | **Prerequisites:** Scala and SBT installed and working on your system, e.g. with the help of [SDKMNAN!](http://sdkman.io/) . 42 | 43 | Run the command below in the root directory of the plug-in in order to build it: 44 | 45 | ``` 46 | sbt downloadPlantuml assembly 47 | ``` 48 | 49 | The plugin is built at `target/scala-2.13/gitbucket-plantuml-plugin-assembly-x.y.z.jar` and it should be copied to ```$GITBUCKET_HOME/plugins/``` directory. 50 | 51 | 52 | License 53 | ---- 54 | 55 |
