    Description

      Create a Java interface with a static method:

      public interface JavaInterface {
   static String getString(String input) {
     return input;
  }
}

       

      A simple Groovy class that uses that:

       

      class Example implements JavaInterface {
   static void main(String[] args) {
     println getString('OK')
  }
}

      Running this works fine in Groovy 3.0.9.

      In Groovy 4.0.0 I get this runtime error:

      Exception in thread "main" groovy.lang.MissingMethodException: No signature of method: static tests.Example.getString() is applicable for argument types: (String) values: [OK]
Possible solutions: toString(), toString(), getAt(java.lang.String)
