Streaming error, StockPrices example

[subashbasnet]

Hello all,

The StockPrices.java example of the given link, 
StreamingExamples
shows error due to lack of SourceContext class in the provided flink-streaming-core jar as given in maven. 

​
So I added another dependency as below in maven:

<dependency>

<groupId>org.apache.flink</groupId>

<artifactId>flink-streaming-core</artifactId>

<version>0.9.0</version>

</dependency>

Now the SourceContext is found, but shows @override error in the inner class StockSource.



Best Regards,

Hey Subash! The example is not part of the Flink distribution (any more). Probably you are running into a version mismatch. The examples packages you are referring to actually sets up all dependencies. How are you trying to run this?

Hello Ufuk,

Yeah I had tried running the examples via eclipse, yeah it should have setup all dependencies but no it doesn't. It shows error with regard to SourceContext not available as explained via image in earlier thread. 
So I had to add this new depedency in maven to get rid of SourceContext not available error as below:

<dependency>

<groupId>org.apache.flink</groupId>

<artifactId>flink-streaming-core</artifactId>

<version>0.9.0</version>

</dependency>

But after adding this dependency the previous SourceContext error get's removed but now another new @override error occurs inside the inner class StockSource, the image of error is attached earlier.

Hi!

Still sounds like a version mixup in your dependencies, or the IDE did not properly pick up the changes (re-import / refresh).
