Question

Is it possible to change gradle’s runtime dependencies according to the what the operation system it is on?

I’m using the SWT in my application which has jars that are platform dependent. I want to only distribute the right SWT jar for each platform it is running. Something like:

dependencies {
    runtime fileTree(dir: 'swt', include: 'swt_win_32.jar') if windows.
    runtime fileTree(dir: 'swt', include: 'swt_linux_x86.jar') if linux.
}

Hope this question make sense. Thanks.

Answer 1

String jarName;
switch(System.getProperty('os.name').toLowerCase().split()[0]) {
  case 'windows':
    jarName = 'swt_win_32.jar' 
    break
  case 'linux':
    jarName = 'swt_linux_x86.jar' 
    break
  default:
    throw new Exception('Unknown OS')
}

dependencies {
  runtime fileTree(dir: 'swt', include: jarName)
}
