Builing DMG often fails when background image is set

[victorkifer]

Info:
OS: High Sierra 10.13.5 (APFS)
Gradle Version: 4.8
Plugin Version: 2.2.1

The plugin configuration is as follow. I have a custom background image for the DMG.

macAppBundle {
    appName = "App"
    appStyle = "Oracle"
    icon = "src/res/icon.icns"
    bundleIdentifier = "com.example"

    mainClassName = "MainKt"

    bundleJRE = true
    jreHome = "/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home"
    jvmVersion = "1.8"
    jarTask = "jar"
    backgroundImage = "src/main/deploy/background.png"
}

The creation of DMG without background image always succeeds.
With background image set it fails most of the time (sometimes rarely succeeds). The error I'm getting is:

Problem running applescript to set dmg background image: 1 78:82: execution error: Finder got an error: Can’t get disk "DiskName". (-1728)

I believe this is due to some kind of racing condition. If you need some extra info, feel free to ask.
