无法从 Storm 教程运行 Storm-starter 拓扑

当遵循 Storm-starter 中的指南时repo https://github.com/apache/storm/tree/master/examples/storm-starter，我无法实际运行任何拓扑 - 就像ExclamationTopology.

mvn clean install -DskipTests=true运行成功，从顶级 Storm 存储库执行，就像那样mvn package at the storm-examples level.

当我尝试跑步时storm jar target/storm-starter-2.0.0-SNAPSHOT.jar org.apache.storm.starter.ExclamationTopology，我收到错误：

Error: A JNI error has occurred, please check your installation and try  again
Exception in thread "main" java.lang.NoClassDefFoundError:   org/apache/storm/topology/IRichSpout

我正在运行 OS X，Java 版本：

java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

Maven 版本 3.3.9。

有谁知道我为什么会收到此错误以及我应该在设置中更改哪些内容？

Edit:

按照以下答案中的建议删除后scope线从pom.xml，这个错误消失了，取而代之的是：

Exception in thread "main" java.lang.ExceptionInInitializerError

Caused by: java.lang.RuntimeException: java.io.IOException: Found multiple defaults.yaml resources. You're probably bundling the Storm jars with your topology jar. [jar:file:/Users/zachary/apache-storm-0.10.0/lib/storm-core-0.10.0.jar!/defaults.yaml, jar:file:/Users/zachary/storm/examples/storm-starter/target/storm-starter-2.0.0-SNAPSHOT.jar!/defaults.yaml]

最终编辑:

对于任何未来的谷歌用户，我最终都没有得到storm-starter通过命令行运行的示例LocalCluster。相反，我使用 Maven 设置了一个新项目，添加storm-core作为依赖项，遵循 [this] (https://github.com/mbonaci/mbo-storm/wiki/Storm-setup-in-Eclipse-with-Maven,-Git-and-GitHub https://github.com/mbonaci/mbo-storm/wiki/Storm-setup-in-Eclipse-with-Maven,-Git-and-GitHub）一般指南。然后，在 Eclipse 中，我能够从以下位置导入正确的包：storm做例子，比如ExclamationTopology。我使用相同的导入重写了该类（更改为import backtype.storm.Config， ETC）。然后，按原样运行该文件就可以了。

This quick https://maven.apache.org/guides/getting-started/maven-in-five-minutes.htmlMaven 指南也有帮助。

尼克的回答更准确一些。

In storm-starter/pom.xml依赖性storm-core指定范围为“provided”：

<dependency>
  <groupId>org.apache.storm</groupId>
  <artifactId>storm-core</artifactId>
  <version>${project.version}</version>
  <!--
    Use "provided" scope to keep storm out of the jar-with-dependencies
    For IntelliJ dev, intellij will load properly.
  -->
  <scope>${provided.scope}</scope>
</dependency>

如果您使用本地运行LocalCluster你需要包括storm-core作为默认范围“compile”的依赖项，即只需删除scope标记并运行mvn -DskipTests package in storm-starter again.
