Try to change your manifest attributes like:

jar {
  manifest {
    attributes(
      'Class-Path': configurations.compile.collect { it.getName() }.join(' '),
      'Main-Class': 'hello.HelloWorld'
    )
  }
}

And then just change 'hello.helloWorld' to '.' (where your Main class has a main method). In this case, you make in your manifest an attribute, which point to this class, then a jar is running.
