I've just seen the same error.

The plugin isn't compatible with jack.

[monemihir]

The moment I set compileOptions to Java8, Android Studio tells me I need to enable jack.

Does that mean I can't use this plugin?

[evant]

They cover the same feature set, use one or the other.

[monemihir]

sorry i don't quite understand...can you please tell me what updates I should do to my gradle file?

[evant]

Do you want to use jack, or retrolambda? Both support backporting lambdas. Jack is "officially supported" but has some known issues currently like slower builds, not compatible with instant run etc.

To use retrolambda, remove:

jackOptions {
  enabled true
}

Ignore any warning from Android Studio, it will work fine.

To use jack, remove:

apply plugin: 'me.tatarka.retrolambda'
...
retrolambda {
    javaVersion org.gradle.api.JavaVersion.VERSION_1_7
}

[monemihir]

Do I still need to set the compileOptions option set?

If I disable jack the project builds properly, but I get an error

Error:Lambda expressions not supported at this language level

If I set the compileOptions then the build asks to enable jack and enabling it and disabling retrolambda the build still breaks with error

Error:Lambda coming from jar file need their interfaces on the classpath to be compiled, unknown interfaces are java.util.function.Supplier

[evant]

Yes, you still need compileOptions, it's described in the README.

retrolambda (and jack) only backport the lambda language feature. They do not backport any java 8 apis so java.util.function.Supplier will not be avaialble before Nouget. jack is doing a little better here failing and compile time, retrolambda will fail at runtime.

[monemihir]

ok cool thanks a lot, i've got it working now

I removed this, it can build, but not run..... jackOptions { enabled true }
