I have reproduced this in SceneBuilder 8.5.0 and 20.0.0 and can't get it to locate the ControlsFX library from maven central. It seems the only way to get ControlsFX added into scene builder is to download the JAR file and add the JAR file manually from the file system. Does anyone know why this happens or how to resolve it? We use maven to manage this library for our project/build tools, and would like to also use maven to manage importing the library into SceneBuilder.
To reproduce:
I have confirmed that I can find other libraries from mavencentral.
Here is what I did for the following version of SceneBuilder.
