@gammanik dsl-lib-support.jar is it included in your plugin?

[gammanik]

yes. It’s in a separate module. I’m using Multi-project build. Do you think switching to composite build could help?

[iguissouma]

You could load dsl-lib-supprt.jar from the plugin directory where it's installed

[iguissouma]

val myIdeaPluginLibPath = toSystemIndependentName(getPluginsPath() + "/my-idea-plugin-name/lib/dsl-lib-supprt.jar")

[gammanik]

I’m loading it from my module’s build folder inside my plugin:

File("/Users/Nikita/Documents/lib-support/dsl-lib-support/build/libs/dsl-lib-support.jar")

Because I want every project using my plugin to be able to use my dsl rules for kotlin scripting. The path is ok and the script can see the dsl-rule classes.
I guess the problem is that ClassLoader is different.

[gammanik]

I actually found the same question
Trying to apply it for my case yet with no luck.

When you run the plugin it will copy all the lib to one directory, and it's different from the build directory, you can get the directory with getPluginsPath() + "/my-idea-plugin-name/lib/"

[iguissouma]

the idea is to add the same jar used by the plugin to the scriptengine classpath

[gammanik]

Thanks for your advice! Unfortunately it wasn’t enough. As I found later I’ve been loading my jar with thread.contextClassLoader which is UrlClassLoader but all of plugins classes are loaded with PluginClassLoader (which is a inherited from UrlClassLoader)
So I manually set:

Thread.currentThread().contextClassLoader = this.javaClass.classLoader

And it accidentally solved the problem.

That what the error message was about:
