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

具體錯誤資訊如下：

Failed to get config java.library.path

cannot concatenate 'str' and 'NoneType' objects
Syntax: [jstorm jar topology-jar-path class ...]

    Runs the main method of class with the specified arguments.
    The jstorm jars and configs in $JSTORM_CONF_DIR/storm.yaml are put on the classpath.
    The process is configured so that StormSubmitter
    (https://github.com/alibaba/jstorm/wiki/JStorm-Chinese-Documentation)
    will upload the jar at topology-jar-path when the topology is submitted.

錯誤原因是：在打jar包的時候，把jstorm-core這個jar包也包含進去了，如下圖：

打包時，移除該jar，再次部署即可。

或者：
在pom檔案中修改storm-core的scope為provided

<dependency>
    <groupId>org.apache.storm</groupId>
    <artifactId>storm-core</artifactId>
    <version>1.1.0</version>
     <!--本地除錯的時候，遮蔽掉scope，等打包部署的時候再放開-->
    <scope>provided</scope>
</dependency>

這樣在idea打包時，就不會包含改 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。這個scope 只能作用在編譯和測試時，同時沒有傳遞性。
