If your project has external library dependencies, you could copy the jars to a folder and add the classpath entries in the manifest.

 def dependsDir = "${buildDir}/libs/dependencies/"
    task copyDependencies(type: Copy) {
    from configurations.compile
    into "${dependsDir}"
   }
task createJar(dependsOn: copyDependencies, type: Jar) {
  
    manifest {
        attributes('Main-Class': 'com.example.gradle.App',
                'Class-Path': configurations.compile.collect { 'dependencies/' + it.getName() }.join(' ')
        )
    }
    with jar
}
