[help] any clue to fix conflicting dependencies?

i encounter a problem:

error : missing or invalid dependency detected while loading class file 'SparkIMain.class‘
Could not access type URLClassLoader in value scala.tools.nsc.util.ScalaClassLoader。

I totally have no idea on how to debug, is there any experience or an clue to fix this ploblem??

Thanks a lot !!!

Begin by reproducing the reported class-loading error and inspecting the dependency versions involved in SparkIMain.class and ScalaClassLoader. Done means identifying the conflicting dependencies and documenting or applying a confirmed fix.
