java spark framework with eclipse

[shinehah.ol...@gmail.com]

I saw the YouTube video on the Java Spark Framework at https://www.youtube.com/watch?v=q7Gbdr75kiU.

I would like to know how the presenter was able to get Spark to work with Eclipse.  Where can I go to get those instructions?

Hi Shinehah!   That is a great presentation on sparkjava[1].    

On their web page they mention the line for gradle.  I was able to get their hello world example working from within eclipse using gradle[2].   I just made a simple project and ran `gradle eclipse`, then imported the existing eclipse project and I was able to run HelloWorld from within eclipse.

Does this work for you too?  Thanks --Matt Payne
