Java.lang.NoSuchMethodError when clear there

Question

General information: I use the Bukkit / Spigot API in git version -Spigot-1d14d5f-ba32592 (MC: 1.8.3) (Implementation of API version 1.8.3-R0.1 -SNAPSHOT), IntelliJ IDEA 14.1.3 and compilation with its compiler default. The java jdk version is 1.8.0_25.

Therefore, when I try to call this class constructor, it throws an exception from the runtime.

As you can see, there is a constructor and, as far as I know, it’s called correctly. So is this error an error in my project setup, API, or something completely different?

The class utilities are in a separate module, and everything works if I insert them into the module of the test plugin, but not inside another module. However, any other constructor in any other class inside me.lakan.util.inventory can be called normally.

Answer 1

The problem was in the structure of the project.

For the test artifact, I chose the module module module util. Fixed its change to the output of the utility module artifact .
