Read [the wiki](https://jmonkeyengine.github.io/wiki) for the installation guide and tutorials. Join [the discussion forum](https://hub.jmonkeyengine.org/) to participate in our community, get your questions answered, and share your projects. Note: The master branch on GitHub is a development version of the engine and is NOT MEANT TO BE USED IN PRODUCTION. ### Technology Stack - windowed, multi-platform IDE derived from NetBeans - libraries for GUI, networking, physics, SFX, terrain, importing assets, etc. - platform-neutral core library for scene graph, animation, rendering, math, etc. - LWJGL v2/v3 (to access GLFW, OpenAL, OpenGL, and OpenVR) or Android or iOS - Java Virtual Machine (v8 or higher) ### Documentation Did you miss it? Don't sweat it, [here it is again](https://jmonkeyengine.github.io/wiki). ### Contributing Read our [contribution guide](https://github.com/jMonkeyEngine/jmonkeyengine/blob/master/CONTRIBUTING.md). ### License [New BSD (3-clause) License](https://github.com/jMonkeyEngine/jmonkeyengine/blob/master/LICENSE.md) ### How to Build the Engine from Source 1. Install a Java Development Kit (JDK), if you don't already have one. 2. Point the `JAVA_HOME` environment variable to your JDK installation: (In other words, set it to the path of a directory/folder containing a "bin" that contains a Java executable. That path might look something like "C:\Program Files\Eclipse Adoptium\jdk-17.0.3.7-hotspot" or "/usr/lib/jvm/java-17-openjdk-amd64/" or "/Library/Java/JavaVirtualMachines/zulu-17.jdk/Contents/Home" .) + using Bash or Zsh: `export JAVA_HOME="` *path to installation* `"` + using Fish: `set -g JAVA_HOME "` *path to installation* `"` + using Windows Command Prompt: `set JAVA_HOME="` *path to installation* `"` + using PowerShell: `$env:JAVA_HOME = '` *path to installation* `'` 3. Download and extract the engine source code from GitHub: + using Git: + `git clone https://github.com/jMonkeyEngine/jmonkeyengine.git` + `cd jmonkeyengine` + `git checkout -b latest v3.7.0-stable` (unless you plan to do development) + using a web browser: + browse to [the latest release](https://github.com/jMonkeyEngine/jmonkeyengine/releases/latest) + follow the "Source code (zip)" link at the bottom of the page + save the ZIP file + extract the contents of the saved ZIP file + `cd` to the extracted directory/folder 4. Run the Gradle wrapper: + using Bash or Fish or PowerShell or Zsh: `./gradlew build` + using Windows Command Prompt: `.\gradlew build` After a successful build, fresh JARs will be found in "*/build/libs". You can install the JARs to your local Maven repository: + using Bash or Fish or PowerShell or Zsh: `./gradlew install` + using Windows Command Prompt: `.\gradlew install` You can run the "jme3-examples" app: + using Bash or Fish or PowerShell or Zsh: `./gradlew run` + using Windows Command Prompt: `.\gradlew run` You can restore the project to a pristine state: + using Bash or Fish or PowerShell or Zsh: `./gradlew clean` + using Windows Command Prompt: `.\gradlew clean` ", Assign "at most 3 tags" to the expected json: {"id":"3581","tags":[]} "only from the tags list I provide: []" returns me the "expected json"
