It is pretty hard to find the reason why the following exception occurs:

Please at least throw an exception will a explanatory message. |

| The stack trace shows that this should not be caused by missing source folder when downloading QuickBuild artifacts. Are you able to reproduce this issue every time when the latest dependency build misses the source folder? |

| I will try to reproduce that and provide more information. But I suspected that's the cause because I already saw that a couple of times and that was always when the dependency build failed and had no artifacts published. |

| I tried but QB simply reports that the directory to fetch does not exist in case there are no artifacts being published. |

Ok I was able to reproduce the HessianProtocolException:
Following steps: 1. Create 2 configurations ("dependency", "build") 2. In "dependency" add one script step with: groovy: throw new Exception("fail") 3. Set build condition in "dependency" to "always build" (just for testing, production builds have the "changes in ref repos") 4. In "build" create a qb repository which checks out everything from "dependency" and use "latest build (or new if necessary) 5. Create a checkout step for this repository in "build" 6. IMPORTANT: Let the "build" config run on another node than the server (I used a ubuntu here) 7. Run the configuration "build" -> it will fail with a hessianprotocolexception |
