Hi, I've been programming for a few years and now I'd like to learn some Java. I thought a good way to do it would be by contributing to ElasticSearch. Keep in mind that I'm a complete noob with everything Java right now. I've cloned ElasticSearch and I'm trying to run it with Gradle. I was able to assemble it, but when I try to run it, I get the following Exception: `Execution failed for task ':distribution:run#wait'.` ... `Caused by: org.gradle.api.GradleException: Failed to start elasticsearch` Please see the output for the task that generated the error here: [Task error debug output](https://justpaste.it/1agtg) (the full output is almost 50000 lines and I don't know how to share it here). Gradle version: ``` ------------------------------------------------------------ Gradle 4.1 ------------------------------------------------------------ Build time: 2017-08-07 14:38:48 UTC Revision: 941559e020f6c357ebb08d5c67acdb858a3defc2 Groovy: 2.4.11 Ant: Apache Ant(TM) version 1.9.6 compiled on June 29 2015 JVM: 1.8.0_144 (Oracle Corporation 25.144-b01) OS: Mac OS X 10.12.6 x86_64 ``` Looking forward to any help! I couldn't find any relevant results on Google. ---

Hi Jörg, Thank you for the quick reply! You saved my ass. I looked more carefully at the area which you said should be relevant for this and, lo and behold, I found that the initial Exception was thrown there (I was confused by the run#wait below). The Exception in cause was a `BindHttpException` and it was thrown due to the fact that the `9200` and `9300` ports were already used by a Docker container running elasticsearch, which I had forgotten to stop. It's up and running now and it appears to be working well. ---
