Solution posted by shawnt...@gmail.com worked for me.

As a workaround, passing 24 instead 'N' to minSdkVersion should fix the issue.

Having Jack accept only ints as min API level might be an issue because those are published after the SDK preview version is published.
I can fix the plugin to pass 'N' for jack.android.min-api-level, but it would require Jack to start accepting preview API versions as well.

Thank you for your feedback. We've decided to add support for Java 8 language features directly into the current javac and dx set of tools, and deprecate the Jack toolchain. For more info please see https://android-developers.googleblog.com/2017/03/future-of-java-8-language-feature.html .
