jOpt is a Java Framework for reducing work and time spent while developing optimization algorithms and performing computational experiments. It is written using Java 8 programming language, so codes that depend on jOpt Framework needs JDK 8 and JRE 8 for compiling and running.

To use jOpt Framework from the compiled .jar file, first you have to download it and its dependencies:

• jopt-1.2.0.jar
• dependency.zip or dependency.tar.gz

After download, you have to extract dependency.zip (or dependency.tar.gz) and add jopt-1.2.0.jar and the dependencies on the classpath.

You may prefer to use just jopt-1.2.0-jar-with-dependencies.jar, which already includes all dependencies.

You can use jOpt Framework with Maven by adding the following to your pom.xml:

<repositories>
  <repository>
    <id>jitpack.io</id>
    <url>https://jitpack.io</url>
  </repository>
</repositories>

<dependencies>
  <dependency>
    <groupId>com.github.andremaravilha</groupId>
    <artifactId>jopt</artifactId>
    <version>1.2.0</version>
  </dependency>
</dependencies>

You can use jOpt Framework with Gradle. First, add the following content in your root build.gradle at the end of repositories:

allprojects {
  repositories {
    ...
    maven { url "https://jitpack.io" }
  }
}

Then, add the dependency:

dependencies {
  compile 'com.github.andremaravilha:jopt:1.2.0'
}
