The JavaEE project is meant to allow SDL compatibility for web applications.

To compile with the latest release of SDL JavaSE, include the following in your app's build.gradle file,

repositories {
    mavenCentral()
}
dependencies {
    implementation 'com.smartdevicelink:sdl_java_se:5.1.0'
}

If you prefer making a JAR, simply call:

gradle build

from within the project and a JAR should be generated in the build/libs folder
