I also noticed that the `jfx` project is still named `rt` in its project file. Please fix that on the way.

While it's possible to run apps, the project structure is wrong in that the source folders are projects and the folders are packages. ColorCube has the right configuration. A follow up for apps and test is needed.

apps/samples/.classpath line 21:

> 19: 	<classpathentry kind="lib" path="Ensemble8/lib/lucene-core-7.7.3.jar"/>

I'm getting the following errors on Samples:

Description	Resource	Path	Location	Type
Project 'samples' is missing required library: 'Ensemble8/lib/lucene-core-7.7.3.jar'	samples		Build path	Build Path Problem
Project 'samples' is missing required library: 'Ensemble8/lib/lucene-grouping-7.7.3.jar'	samples		Build path	Build Path Problem
Project 'samples' is missing required library: 'Ensemble8/lib/lucene-queryparser-7.7.3.jar'	samples		Build path	Build Path Problem
Project 'samples' is missing required source folder: '3DViewer/src/test/java'	samples		Build path	Build Path Problem
Project 'samples' is missing required source folder: '3DViewer/src/test/resources'	samples		Build path	Build Path Problem

Indeed, there is no `3DViewer/src/test` folder. How do you not get errors?

apps/toys/.classpath line 9:

> 7: 	</classpathentry>
> 8: 	<classpathentry kind="src" path="FX8-3DFeatures/src"/>
> 9: 	<classpathentry kind="src" path="Hello/src/main/java"/>

Why are these the only 2 sources?

build.gradle line 2508:

> 2506:             // Create empty hlsl dirs on all platforms for IDE support
> 2507:             file("$project.buildDir/hlsl/Decora").mkdirs()
> 2508:             file("$project.buildDir/hlsl/Prism").mkdirs()

You need to create `build/gensrc/jsl-decora` and `build/gensrc/jsl-prism` too if they are not declared as optional sources in the classpath.

buildSrc/.settings/org.eclipse.core.resources.prefs line 2:

> 1: eclipse.preferences.version=1
> 2: encoding/<project>=UTF-8

This file can be removed too since buildSrc is not a project.
