`Could not find method jackOptions() for arguments` when building Tensorflow Lite demo

Question

I'm trying to build the demo app in Tensorflow Lite:

https://www.tensorflow.org/lite/demo_android

Relevant versions:

• Tensorlow Lite: 1.12
• Android Studio: 3.2.1
• Android Sdk: android-28

When I try to make the project included at tensorflow/lite/java/demo I get a build error:

Could not find method jackOptions() for arguments

Presumably this relates to Jack and Jill being deprecated as noted in this related SO article: Could not find method jackOptions() for arguments.

However I'm unclear how it's being used in the Tensorflow demo. My best guess is that using an older version of the SDK might be a temporary solution, so if anyone knows what versions of the various APIs/SDKs will build successfully I would love to know. Or if there's another solution I might apply.

Answer 1

It appears that you can pass this build error by commenting out lines 15, 16, 17 in tensorflow/lite/java/demo/app/build.gradle in the demo app provided in the demo source.

jackOptions {
    enabled true
}

This moved me onto another build error at least. I may update this later if there are more relevant details.
