Hi, I tried to execute Stardog example from [GitHub - stardog-union/stardog-examples: Examples for working with and extending Stardog](https://github.com/stardog-union/stardog-examples). I was able to build it but unable to execute. ![Gradle( build succeed)](https://canada1.discourse-cdn.com/flex030/uploads/stardog/original/1X/577fdda5616a568cb385150ac76bbafbe683724e.JPG) ![Gradle1(ex2) deprecated](https://canada1.discourse-cdn.com/flex030/uploads/stardog/original/1X/73e7cc7d3cdbd5d86dfb4ffea80051accd4d1198.JPG) I changed my gradle version to 3.4.1 but still error. any tips? ---

Can you execute the example using the `-i` option to Gradle? This will show the exception thrown by the program. ---

When I build it it said " :compileJava NO-SOURCE :examples:compileJava NO-SOURCE :examples:analyzer:compileJava ![no-source](https://canada1.discourse-cdn.com/flex030/uploads/stardog/original/1X/4099c4566652821e5bf41a63c899685f7fdeca77.jpg) ---

Here is what I did: I downloaded the code, I use cd command to go to directory of example. I used " gradle compileJava" command > > it said build successful. > > But why no source! ---

It looks like there was a minor mistake in the README file. I’ve corrected it. The command to execute the example is: `gradle execute -PmainClass=com.complexible.stardog.examples.api.ICVExample` Hope this helps. ---

It appears that this is a problem specific to Gradle and windows 10. We will have to investigate further as the Gradle folks don’t seem to have a solution. ---

Thanks for reply, I think this is a problem with gredle itself. Do to the versioning some statements are obsolete. Which version of grade is tested so I can use the very exact one ---
