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

Hi,

after adding compile 'com.google.guava:guava:21.0' to my Android project Gradle’s dependencies, I got this build error:

I’m already using:

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
...
 jackOptions {
            enabled true
        }

compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

Gradle’s project configuration snippet:

     classpath 'com.android.tools.build:gradle:2.5.0-alpha-preview-01'
     classpath 'me.tatarka:gradle-retrolambda:3.2.5'

In gradle-wrapper.properties I have:

     distributionUrl=https://services.gradle.org/distributions-snapshots/gradle-3.5-20170213202653+0000-all.zip

Could you provide any resolution to this problem?

Java 8 support: compile ‘com.google.guava:guava:22.0-android’

That’s all we’ve got for you, sorry 😦 If it’s any consolation, Guava 21 adds almost nothing except the Java 8 features. We should have Guava 22 (with Android-compatible version) our in the coming quarter.
