Getting java.lang.AbstractMethodError on implemented method

Question

As the title states, I get a java.lang.AbstractMethodError on a method that is definitively implemented by my class. The complete error message is:

Answer 1

Make sure you have the latest jar file in your class path not a older copy. If you are seeing this at run time this happens due to incompatible binaries

From Oracle java site

Thrown when an application tries to call an abstract method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of some class has incompatibly changed since the currently executing method was last compiled.

Also try the -U flag forces to update dependencies.

mvn clean install -U
