skipWhenEmpty not working in stone.gradle

[bcr]

Building via ./gradlew build, line 128 in stone.gradle causes the build to stop due to missing property skipWhenEmpty:

Blakes-MBP:dropbox-sdk-java blake$ ./gradlew build
Set JDK6_HOME environment to disable boot classpath warnings.

FAILURE: Build failed with an exception.

* Where:
Script '/Users/blake/Source/OpenSource/dropbox-sdk-java/stone.gradle' line: 128

* What went wrong:
A problem occurred evaluating script.
> No such property: skipWhenEmpty for class: org.gradle.api.internal.tasks.DefaultTaskInputs

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 3.44 secs

Commenting out this line works fine:

// inputs.dir(getSpecFiles).skipWhenEmpty = true

I am using commit 5b3ee2867f63cd2ccc4b2ed550633449fb570ec1

Thanks for the report! We'll look into it.

It's now 5 years in the future, but we are using Java 11 to do all of our builds at this point in time to create a Java 1.8 compatible JAR. Going to close this due to inactivity.
