DefaultServiceRegistry之findProviderMethods

    private void findProviderMethods(Object target) {
        Set<String> methods = new HashSet<String>();
        for (Class<?> type = target.getClass(); type != Object.class; type = type.getSuperclass()) {
            findDecoratorMethods(target, type, methods, ownServices);
            findFactoryMethods(target, type, methods, ownServices);
        }
        findConfigureMethod(target);
    }

	findDecoratorMethods(target, type, methods, ownServices);
	从target自己开始，一直到all super class
	声明的函数中以create开头，参数一个并且参数类型和返回类型一致的，
	以new DecoratorMethodService(target, method) 加入到ownService变量维护的list<Provider>中 type：DecoratorMethodService
	例如：
	org.gradle.api.internal.plugins.PluginRegistry org.gradle.internal.service.scopes.GradleScopeServices.createPluginRegistry(
						org.gradle.api.internal.plugins.PluginRegistry
						)

findFactoryMethods(target, type, methods, ownServices);
从target自己开始，一路找到所有super class
声明的函数中名字以create开始的，都加入到自己维护的ownServices成员的list<Provider>中 type：FactoryMethodService

findConfigureMethod(target);
target和所有基类，方法叫cofigure 返回void的
例如void org.gradle.internal.service.scopes.GlobalScopeServices.configure(
	org.gradle.internal.service.ServiceRegistration,
	org.gradle.initialization.ClassLoaderRegistry
	)
把改method的参数换个类型， invoke，具体参见
void org.gradle.internal.service.DefaultServiceRegistry.findConfigureMethod(Object target)
