If you work on a multi-module project Try this out

restart.exclude.protobuf-common=/protobuf-common/

Thank you @minwoox

It seems to be a problem due to the different class loader.

    private Constructor<T> getConstructor0(Class<?>[] parameterTypes,
                                        int which) throws NoSuchMethodException
    {
        ReflectionFactory fact = getReflectionFactory();
        Constructor<T>[] constructors = privateGetDeclaredConstructors((which == Member.PUBLIC));
        for (Constructor<T> constructor : constructors) {
            if (arrayContentsEq(parameterTypes,
                                fact.getExecutableSharedParameterTypes(constructor))) {
                return constructor;
            }
        }
        throw new NoSuchMethodException(methodToString("<init>", parameterTypes));
    }
