Eclipse: ClassNotFoundException: com.sun.prism.shader.FillPgram_Color_Loader

Kevin:
The four classpath entries in question are
build/hlsl/Prism
build/gensrc/jsl-prism
build/hlsl/Decora
build/gensrc/jsl-decora
once added to the Eclipse .classpath file (in graphics) I see two warnings (on Mac):
Project 'graphics' is missing required source folder: 'build/hlsl/Decora' Build path graphics
Project 'graphics' is missing required source folder: 'build/hlsl/Prism' Build path graphics
For the moment I cannot verify the situation on Windows or Linux, but I think Nir mentioned that these directories might be created on Windows, so this is my current assumption.
The problem in Eclipse is that these warnings (incomplete build path) cannot be turned off. One solution is to (re)create the missing directories manually after each [gradle clean]. The other solution is to modify gradle build to always create these directories, even if they are not used. This step is usually in ‘init’ target in the builds that utilize clean-init-build cycle.
What could be the problem in creating empty directories?
* Is there a way to make it conditional?
In theory, yes, via classpath variables:
https://stackoverflow.com/questions/495264/how-can-i-specify-an-eclipse-classpath-entry-for-specific-o-s-platform
I’ve never used this before. So far these directories are the only place where we have platform differences in the classpath.
Could someone with a Windows machine verify that 'build/hlsl/Decora' and 'build/hlsl/Prism' are not empty please?
Thank you

So these folders are not needed to compile, but they are needed to run.
I suggest we bring them back to .classpath

and also modify build.gradle to create all 4 folders as a part of the corresponding target.
I am not in favor of this change. There are platform-specific parts of the build, so IDEs should be able to adapt to this.

Hi Nir,
thanks for the explanation - though I have no idea why Eclipse wants
them (see them again after re-adding as source folders and all running
as before).
Not sure where to go from here, would prefer not to have a local
classpath that differs from the one in the repository .. hmm
