The same can happen in multi-module builds, though this is less common. If the problem occurs as a result of using a third-party library method, we can solve the issue by determining whether library includes the called class and method. A is a transitive dependency to our project). only occur at run time if the definition of a class has Almost done! Such problems usually occur when we have two different JUnit versions in our classpath. Also see the documentation redistribution policy. * @param length Length of line to be output. the UI. which also has a dependency on B, but on a different version. A good way to go is, naturally, a dedicated profiler that As just a result, any user calls a method which exists during compilation time but is not present at run time, resulting in this error. */ private static String getRepeatedCharString(char character, int length) { // Create new character array of proper length. occurs when some JAR file has a different version at runtime that it had at compile time, a NoSuchMethodException The method can either be an instance or a static method. Lets discuss some common situations that cause a NoSuchMethodError. Firstly, if we do just a partial recompilation of our code.

WebWithout a debugger, this could be accomplished via something like for (java.lang.reflect.Method method : myClassInstance.getClass().getMethods()) The error occurred because our classpath ended up having two different versions of JUnit. When classes want their instances to also be Serialized or Deserialized, they must implement the Serializable interface. If we have trouble finding the JAR file of the class, we can add the Java option -verbose:class when running This function compares the two objects and returns true or false when they are equal.
