I'm working on an Android library that allows communication with a Bluetooth device. The library itself has two important dependencies.
The goal is to make an .aar available of the library for others to include in their apps, with a sample app being available for reference.
I'm currently working on the sample app, and I've successfully imported the library into the app, but the library's dependencies are not being included so I'm receiving errors such as java.lang.NoClassDefFoundError: Failed resolution of: ...
It was my understanding that the library's gradle file would be used when compiling the library, but this does not seem to be the case?
My library's gradle file is as follows:
apply plugin: 'com.android.library'
apply plugin: 'me.tatarka.retrolambda'
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'me.tatarka:gradle-retrolambda:3.6.0'
}
}
repositories {
mavenLocal()
}
android {
compileSdkVersion 25
buildToolsVersion '25.0.3'
defaultConfig {
minSdkVersion 19
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
publishNonDefault true
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:support-annotations:25.3.1'
compile 'com.polidea.rxandroidble:rxandroidble:1.3.2'
compile 'com.github.zafarkhaja:java-semver:0.9.0'
testCompile 'junit:junit:4.12'
}
Any ideas?

I am new to Android Studio. I am now using Android Studio 2.2.1 due to my study. I found the relevant answer on the website, I tried all solution but I still doesn't work.
android {
compileSdkVersion 28
buildToolsVersion "28.0.3"
defaultConfig {
applicationId "com.quynhnhu.demoapp"
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile'com.android.support:appcompat-v7:28.+'
testCompile 'junit:junit:4.12'
}
You need to include the google maven repository for com.android.support:appcompat-v7:28.+ in your project/root build.gradle. So, change your build.gradle to include the repository like the following:
allprojects {
repositories {
maven {
url 'https://maven.google.com'
}
}
}
more details at Support Library Setup.
Note: please update your gradle version and Android Studio.
I'm beginner with android and gradle. I saw this error so I removed the hamcrest dependency from my module gradle but I still see the following error:
Error:Execution failed for task ':app:preDebugAndroidTestBuild'.
Conflict with dependency 'org.hamcrest:hamcrest-core' in project ':app'. Resolved versions for app (1.1) and test app (1.3)
differ.
This dependency is causing the problem:
compile 'com.android.support.test:testing-support-lib:0.1'
app grade:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
classpath 'com.google.gms:google-services:3.1.0'
}
}
allprojects {
repositories {
google()
jcenter()
maven {
url "https://maven.google.com"
}
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
module gradle (I have a single module):
apply plugin: 'com.android.application'
android {

defaultConfig {
applicationId "com.example.stavalfi.app1"
minSdkVersion 18
targetSdkVersion 26

compile 'com.android.support.test.uiautomator:uiautomator-v18:2.0.0'
}//testImplementation
apply plugin: 'com.google.gms.google-services'
What I have tried:
//testCompile 'junit:junit:4.12'
testCompile('junit:junit:4.12') { // Prevent duplication conflicts
exclude module: 'hamcrest-core'
exclude module: 'hamcrest-library'
exclude module: 'hamcrest-integration'
}
But I get the same error.
I also saw this solution but I don't know where to add the configurations exactly:
Robolectric 3.0-rc2 Hamcrest-core conflict
And I don't see why I need to have this problem if I don't use hamcrest anyway.
Thanks!
add configuration.all below buildtypes.
configurations.all {}
android {
compileSdkVersion 26
defaultConfig {
applicationId "com.nfs.ui.notesapp"

I am creating a blank project in which I add mapbox navigation package compile 'com.mapbox.mapboxsdk:mapbox-android-navigation:0.6.3' in the gradle file. It shows error in appcompat file like this:-
Error:Failed to resolve: com.android.support:appcompat-v7:26.1.0
eventhough I use different version of Appcompat file. Before adding navigation package, everything was fine. Can someone please help me to find out this weird error.
Here is my app's gradle file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "26.0.2"
defaultConfig {
applicationId "com.example.aadhilahmed.test7"
minSdkVersion 15
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.mapbox.mapboxsdk:mapbox-android-navigation:0.6.3'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
}
Specify:
compile ('com.mapbox.mapboxsdk:mapbox-android-navigation:0.6.3') {
transitive = false;
}
Try this.Starting from version 26 of support libraries make sure that the repositories section includes a maven section
allprojects {
repositories {
jcenter()
maven {
url "https://maven.google.com"
}
}
}
For Gradle build tools plugin version 3.0.0
allprojects {
repositories {
jcenter()
google()
}
}
I created an Android library named "core" that use the Logger library (https://github.com/orhanobut/logger).
Here its build.gradle:
apply plugin: 'com.android.library'
android {
compileSdkVersion 25
buildToolsVersion "25.0.1"
defaultConfig {
minSdkVersion 16
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.orhanobut:logger:1.15'
compile 'com.android.support:appcompat-v7:25.0.1'
testCompile 'junit:junit:4.12'
}
Then I build a .aar of core library.
I add this library as a dependency into my application, by putting the .aarcore files in the libs folder.
That's the build.gradle of my application :
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.1"
defaultConfig {
applicationId "com.package.test"
minSdkVersion 16
targetSdkVersion 25
multiDexEnabled true
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
repositories {
mavenCentral()
jcenter()
flatDir {
dirs 'libs'
}
}
dependencies {
compile 'com.mypackage:core:1.0#aar'
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:25.0.1'
compile 'com.android.support:multidex:1.0.1'
}
As you can see I have multidex activated.
It compile just fine but at runtime, at the first call to Logger I get an exception:
stack=java.lang.NoClassDefFoundError: Failed resolution of: Lcom/orhanobut/logger/Logger;
Even if I set transitive = true
compile (com.mypackage:core:1.0#aar) {
transitive=true
}
it doesn't work.
Thank you !
I had to do a couple of things in concert to get it to work.
1) In your library project
Add the following to your project-level gradle file:
buildscript {
dependencies {
classpath 'com.github.dcendents:android-maven-gradle-plugin:2.1'
}
}
Be sure to use the right version of the plugin for your gradle version, check here.
Add the following to your module-level gradle file:
apply plugin: 'com.github.dcendents.android-maven'
group='com.github.YourPackage'// Doesn't have to be github, just an example
Also in this file, make sure your dependencies (the ones you want to be transitive) use api instead of implementation if you are using Gradle 3.4+. If you are using a version of Gradle <3.4, compile is the way to go. Example:
dependencies {
api 'com.google.android.gms:play-services-location:15.0.1'
}
2) In your app project (which uses the library)
Add the following to your module-level gradle file:
dependencies {
implementation('com.github.YourPackage:yourRepo:version#aar') {
transitive=true
}
}
Add the following to you project-level gradle file (but this will depend on where your library is served from, for me it's jitpack):
allprojects {
repositories {
...
maven {
url 'https://jitpack.io'
credentials { username 'yourAuthKey' }// Only for private repositories
}
}
}
Note: You shouldn't add the auth key as a string in build.gradle, put it in a property in your gradle.properties file.
Note 2: JitPack allows you to use for example development-SNAPSHOT as a version number for a gradle dependency. Android Studio caches these dependencies and will not re-download it when you push to your development branch. To overcome this, use commit hashes as version numbers during development or clear (delete) the cache files, located on Windows at ~/.gradle/caches/modules-2/metadata-x.xx/descriptors/com.github.YourPackage/yourRepo. (Needles to say, I learned this the hard way).
Does anybody know how to use Android Annotations with the jack compiler ?
Here my app/build.gradle and here my project build.gradle
With this configuration, I have this error message when I build my project :
Error:Could not get unknown property 'classpath' for task ':app:transformJackWithJackForDebug' of type com.android.build.gradle.internal.pipeline.TransformTask.
You should remove the android-apt plugin and the apt block completely, because it does not work with Jack annotation processing. Also, you have to declare processsors in the annotationProcessor configuration. Lastly, you have to add the annotation processing parameters to jack (which has no public API per-variant, yet).
