Charmatcher.whitespace() was introduced in Guava 19. Looks like you have some code that compiles against Guava 19, but end up with something earlier than that on the classpath.

my tries to fix the issue remove jack options , I got this error `org.gradle.execution.TaskSelectionException: Task ',' not found in root project 'Reaya'.`
any one can help me to fix my issue
thank you

1.update the Android studio to 2.1 or higher version;
2.delete the "apply plugin: 'me.tatarka.retrolambda'"
Try it!

removing the lines apply plugin: 'me.tatarka.retrolambda' worked for me.

Might stick to retrolambda. Some discussions on jack can be found here

check all your libraries you use, including dependencies of the libraries and make sure there are no conflicting versions.
open terminal from Android Stodio and type in: "./gradlew clean"
build again

Gebish on Android

im currently trying to add gebish into my project. I added the dependencies in my build.gradle, but it says :
Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/services/org.codehaus.groovy.transform.ASTTransformation

I often had "duplicate" problems, but i can't solve this one. What's the best i can do in this kind of situations? I mean i just do what the Doc says and copy-paste, but i get these errors.
build.gradle
apply plugin: 'com.android.application'
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'
}
}
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.example.muco.staemme"
minSdkVersion 19
targetSdkVersion 23
versionCode 1
versionName "1.0"
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
dexOptions {
incremental true
javaMaxHeapSize "4g"
}
}
dependencies {
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.2.1'
compile "org.gebish:geb-core:0.13.1"
compile "org.seleniumhq.selenium:selenium-firefox-driver:2.52.0"
compile "org.seleniumhq.selenium:selenium-support:2.52.0"
}

I just had to add
android.packagingOptions {
exclude 'META-INF/services/org.codehaus.groovy.transform.ASTTransformation'
exclude 'META-INF/LICENSE.txt'
}
and now it works.
