Unable to run a storm-starter topology from the Storm tutorial

When following the guide in the storm-starter repo, I'm unable to actually run any topology- like the ExclamationTopology.

mvn clean install -DskipTests=true ran successfully, executed from the top level Storm repo, as did mvn package at the storm-examples level.

When I try to run storm jar target/storm-starter-2.0.0-SNAPSHOT.jar org.apache.storm.starter.ExclamationTopology, I get the error:

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

I'm running OS X, Java version:

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 version 3.3.9.

Does anyone have any ideas on why I'm getting this error and what I should change in my setup?

Edit:

After following the suggestions in the answers below of removing the scope line from the pom.xml, this error was gone, but replaced by:

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]

Final Edit:

For any future googler, I ended up not getting the storm-starterexamples running via the commandline on a LocalCluster. I instead set up a new project with Maven, adding storm-core as a dependency, following [this] (https://github.com/mbonaci/mbo-storm/wiki/Storm-setup-in-Eclipse-with-Maven,-Git-and-GitHub) general guide. Then, in Eclipse, I was able to import the right packages from storm to do the examples, like ExclamationTopology. I rewrote that class using the same imports (changed to import backtype.storm.Config, etc). Then, running the file as is just works.

This quick Maven guide helps too.

To be little bit more precise with regard to Nick's answer.

In storm-starter/pom.xml the dependency storm-core is specified with scope "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>

If you run locally using LocalCluster you need to include storm-core as dependency with default scope "compile", ie, just remove the scope tag, and run mvn -DskipTests package in storm-starter again.
