yes i did and thank you for helping me, the ve project is the folder where everything is installed when i open eclipse i have no missing file, just to be more precise is the example ready to run or should i edit it before ? because i didn't found any minecraft version for this example mod so this is maybe why it's failing to run
i also forgot to tell that when i runed `gradlew genEclipseRuns` and `gradlew eclipse` it's build successfully but i also have before Deprecated Gradle features were used in this build, making it incompatible with Gradle 5.0 even if the installation completed(it may has something to do with that ). i found that this is a common warning but no solution in other topics (and also in github)
