所以..
我有一个集成测试，使用mvn clean test终端运行没有任何问题 - 所以IDE的问题不是代码本身。
Intellij Idea版本： 14.1.4 ，构建： 141.1532
从intellij运行导致异常：
java.lang.NoSuchMethodError: org.yaml.snakeyaml.Yaml.<init>(Lorg/yaml/snakeyaml/constructor/BaseConstructor;Lorg/yaml/snakeyaml/representer/Representer;Lorg/yaml/snakeyaml/DumperOptions;Lorg/yaml/snakeyaml/resolver/Resolver;)V

任何想法？
