The Jme3-utilities Project contains Java packages and assets, developed for sgold's jMonkeyEngine projects, which might prove useful in similar projects.

It contains 4 sub-projects:

1. nifty: the jme3-utilities-nifty library for using NiftyGUI user interfaces with jMonkeyEngine
2. x: the jme3-utilities-x library of experimental software
3. moon-ccbysa: assets for a realistic Moon in SkyControl
4. tests: demos, examples, and test software

The SkyControl library, formerly a sub-project, is now a separate project at GitHub.

The textures sub-project is now part ofthe SkyControl Project.

The jme3-utilities-heart library, formerly a sub-project, is now Heart, a separate project at GitHub.

The jme3-utilities-debug library, formerly a sub-project, is now part of the Heart Library.

The jme3-utilities-ui library, formerly a sub-project, is now Acorus, a separate project at GitHub.

The Minie library, formerly a sub-project, is now a separate project at GitHub.

The Wes library, formerly a sub-project, is now a separate project at GitHub.

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 Jme3-utilities source code from GitHub:

• git clone https://github.com/stephengold/jme3-utilities.git
• cd jme3-utilities
• git checkout -b latest nifty-0.9.37

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, Maven artifacts will be found in "*/build/libs".

You can install the artifacts to your local Maven repository:

• using Bash or Fish or PowerShell or Zsh: ./gradlew install
• using Windows Command Prompt: .\gradlew install

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
