When used in gradle plugin, it throws Unable to load class 'io.github.classgraph.ClassGraph'

Hi,

I’m using the ClassGraph library inside a custom gradle plugin: https://github.com/RoRoche/plantuml-gradle-plugin/tree/feature/using_classgraph

It’s OK during unit testing and while releasing into local Maven and used in another project.

But since it has been released to gradle plugin portal (https://plugins.gradle.org/plugin/com.github.roroche.plantuml), when using inside another project (https://github.com/RoRoche/eo-plantuml-builder), when running my buildClassDiagram task, it throws

* What went wrong:
Execution failed for task ':buildClassDiagram'.
> Lio/github/classgraph/ClassGraph;

Any idea of what’s going wrong? Gradle plugin packaging?

That can be obtained with:

project.getConfigurations().named(JavaPlugin.COMPILE_CLASSPATH_CONFIGURATION_NAME);

Glad you solved it, @RoRoche!

Thanks for all the help, @thc202! I really don’t know anything about Gradle, so couldn’t have come up with the solution easily. Not many community members jump in on bug reports – I’m curious how you saw this bug and decided to help resolve the issue?
