# scripting

[nickheitz]

Hi all... Apologies for the rushed message, but I'm hoping the solution simply occurs to someone.
I have some code that compiles string into kotlin code, via the scripting host and the JVM script compiler. This works in kotlin 1.5.32, but breaks under 1.6.10, throwing the following...

Caused by: java.lang.ClassNotFoundException: com.intellij.openapi.util.Disposer
	at java.net.URLClassLoader.findClass(URLClassLoader.java:382)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:418)
	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:352)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:351)

Is there an easy resolution here?

Please, check your classpath. This is most likely a mismatch between kotlin -unshaded libs and regular ones. The com.intellij.openapi.util.Disposer should not be used unless you're using some -unshaded jar or trying to use compiler internals directly, instead of using it via scripting libs. (i.e. in the normal case it should be relocated to the different package).

Hmm. Ok, any hints on where I should look? The classpath I am using contains all the following kotlin based jars, none of which are explicitly unshaded. Are there likely to be conflicts in this set?

Seems that @ilya.chernikov was absolutely correct... The presence of "non-embeddable" jars for "scripting-compiler" and "scripting-compiler-impl" was exactly the problem. Not the easiest to track down, but easy to fix.
