JStorm Found multiple defaults.yaml resources. You're probably bundling the Storm jars with your top

具体错误信息如下：

错误原因是：在打jar包的时候，把jstorm-core这个jar包也包含进去了，如下图：

打包时，移除该jar，再次部署即可。

或者：
在pom文件中修改storm-core的scope为provided

<dependency>    <groupId>org.apache.storm</groupId>    <artifactId>storm-core</artifactId>    <version>1.1.0</version>     <!--本地调试的时候，屏蔽掉scope，等打包部署的时候再放开-->    <scope>provided</scope></dependency>

这样在idea打包时，就不会包含改 jar了。

小注：
provided是表明了dependency 由JDK或者容器提供，例如Servlet AP和一些Java EE APIs。这个scope 只能作用在编译和测试时，同时没有传递性。
