Issue running basic example locally

[Andres Angel]

Hello everyone, 

I'm using IntelliJ in a ubuntu environment with java 1.8 to run my Flink framworks. My goal is consume few kinesis stream services and build a sort of pipeline. Initially I have build my pom.xml file attached and a test java class attached too.

However , once I run my class from the IDE and getting this error:

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/flink/streaming/api/functions/source/SourceFunction

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:349)
at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

I think I dont need to install or consifure any flink service before run my job via IDE , please if someone could give me a hand with this issue I would appreciate it.

thanks

Hi Andres,

`<scope>provided</scope>` of flink-streaming-java seems suspicious, can you
remove it and see what happens?
