Problem
Is there a tutorial explaining how to properly create a Java Gradle project and build the .jar file? When I create a Java project and add Gradle: File -> New -> Module -> Gradle -> ... I receive errors about Java EE websocket's not available (I'm using Ultimate Edition). However, I can successfully create a project by selecting File -> New -> Project-> Gradle -> which gives me a Java project with Gradle that I can debug. However, when I try to create an artifact (.jar file) I receive errors. I assume the errors stem from mistakes I made in the project structure settings. ``` Buildfile: build.xml does not exist! Build failed ``` or ``` Error: Could not find or load main class Main ``` My project is such a mess at this point, maybe I should create another project, then copy/paste the Main.class and Gradle's dependencies from the old project onto the new project. If this is my best option, how do I correctly create the project this time?
