Rejecting re-init on previously-failed class java.lang.Class: java.lang.NoClassDefFoundError

Question

I see an information log in my console that looks like an error. It is printed from \"art\", which is generally associated to memory but I need help understanding what it me

Answer 1

java.lang.NoClassDefFoundError indicates, that something was found at compiletime but not at runtime. Maybe you just have to add it to the Classpath.

Right click on your project and select -> Compile Module, and then re-start the project and it should work again.
