Updated Answer (Dec. 2, 2020)
Latest Gradle: 6.5
Version check:
./gradlew -v
How to update:
Set URL: ./gradlew wrapper --gradle-version=6.5 --distribution-type=all
Update: ./gradlew wrapper
Latest Android Gradle Plugin: 4.1.0
If you add the following code snippet to the top of your build.gradle file. Gradle will update the build tools.
buildscript {
repositories {
google() // For Gradle 4.0+
maven { url 'https://maven.google.com' } // For Gradle < 4.0
}
dependencies {
classpath 'com.android.tools.build:gradle:4.1.0'
}
}
Read more here: https://developer.android.com/studio/build/index.html and about version compatibility here: https://developer.android.com/studio/releases/gradle-plugin.html#updating-gradle and https://dl.google.com/dl/android/maven2/index.html.
Original Answer
I had this same error, you need to make sure your Gradle version is compatible with your Android Gradle Plugin.
The latest version of Gradle is 2.0 but you need to use 1.12 in order to use the Android Gradle Plugin.
This can happen if you miss adding the Top-level build file.
Just add build.gradle to top level.
It should look like this
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.xx.y'
}
}
allprojects {
repositories {
mavenCentral()
}
}
In my case, I download the project from GitHub and the Gradle file was missing. So I just create a new project with success build. Then copy-paste the Gradle missing file. And re-build the project is working for me.
Root-gradle file:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:x.x.x'
}
}
allprojects {
repositories {
jcenter()
}
}
Gradle-wrapper.properties file:
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-x.x-all.zip
In the project level build.gradle file, I have replaced this line
classpath 'com.android.tools.build:gradle:3.6.3'
with this one
classpath 'com.google.gms:google-services:4.3.3'
After adding both of those lines, and syncing, everything became fine.
Hope this will help someone.
I am writing this not as a solution meant for many, but for some people who may commit a simple mistake like specifying the wrong url for importing projects from SVN. It is intended for those guys :)
This happened to me when I imported the project from SVN -> automatic prompt by Studio to open the project -> It asked for Gradle location -> D:\Software\Android\gradle-2.5 -> Then the error.
The same project in a different SVN branch works fine with the Gradle plugin and Gradle which I have configured in Studio. I tried changing Android Gradle plugin and Gradle to get it working on the erring branch without any success.
Finally, I figured out that it was my following mistake:
I tried importing a specific Application alone instead of importing the application along with dependent library projects.
The url which I used for import initially had the Application porject's name at the end. Once I removed it, and specified the parent directory which contained both application project and its dependent project, everything went smooth :)
I found the problem after one hour struggling with this error message:
I accidentally renamed the root build.gradle to filename in builde.gradle, so Android Studio didn't recognize it anymore.
Renaming it to build.gradle resolved the issue!
I still got the error
Could not find com.android.tools.build:gradle:3.0.0.
Problem: jcenter() did not have the required libs
Solution: add google() as repo
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:3.0.0"
}
}
I was using IntelliJ IDEA 13.1.5 and faced with the same problem after I changed versions of Picasso and Retrofit in dependencies in build.gradle file. I tried use many solutions, but without result.
Then I cloned my project from remote git (where I pushed it before changing versions of dependencies) and it worked! After that I just closed current project and imported old project from Gradle file to IntelliJ IDEA again and it worked too! So, I think it was strange bug in intersection of IDEA, Gradle and Android plugin. I hope this information can be useful for IDEA-users or anyone else.
Go to your grade file where you can see this:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
And change classpath to this:
buildscript {
repositories {
jcenter()
}
dependencies {
// classpath 'com.android.tools.build:gradle:2.1.0'
classpath 'com.android.tools.build:gradle-experimental:0.7.0-alpha1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
The other answers didn't work for me, I guess something wrong happens between ButterKnife and 3.0.0 alpha5.
However, I found that when I annotated any one sentence, either BUtterKnife or 3.0.0 alpha5, it works normally.
So, you should just avoid the duplication or conflict.
For future reference: For me, this issue was solely caused by the fact that I wasn't running Android Studio as administrator. I had the shortcut on Windows configured to always run as administrator, but after reinstalling Android Studio, the shortcut was replaced, and so it ran without administrator rights. This caused a lot of opaque errors, including the one in this question.
This issue happened when I accidently renamed the line
apply plugin: 'com.android.application'
on file app/build.gradle to some other name. So, I fixed it by changing it to what it was.
[FOR FLUTTER] go to your build Gradle then check if you have three paths
dependencies {
classpath 'com.android.tools.build:gradle:3.5.0'
classpath 'com.google.gms:google-services:4.3.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
I somehow removed the android tools classpath and was getting the error.
This just happened to me using Android Studio 1.3.2, however, since I had just created the project, I deleted it and created it again.
It seems that it had not been properly created by Android Studio the first time, not even the project folders where as expected.
If you run a the module task with android plugin 1.2.3 in module directory , the problem appears. Try this:
../gradlew -b ../build.gradle -c ../settings.gradle :module:xxx
Make sure your two build.gradle and settings.gradle files are in the correct directories as stated in https://developer.android.com/studio/build/index.html
Then open "as existing project" in Visual Studio
Gradle is very finicky about this.
I got this error message after making the following change in my top-level build.gradle to update to the latest version of gradle:
//classpath 'com.android.tools.build:gradle:2.3.2' old
classpath 'com.android.tools.build:gradle:2.3.3' //new
I foolishly made the change while I was connected behind a hostile workplace proxy. The proxy caused the .jar files for the new version of gradle to become corrupt. This can be verified by inspecting the jars to see if they are an unusual size or whether they can be unzipped.
In order to fix the mistake, I connected to my network at home (which is not behind a proxy) and did a refresh dependencies from the Terminal:
./gradlew --refresh-dependencies
This caused the newer version of gradle to be re-downloaded and the error no longer occurs.
Check the spelling, mine was 'com.android.aplication'
This may also happen when you have both settings.gradle and settings.gradle.kts files are present in project root directory (possibly with the same module included). You should only have one of these files.
i had similar problem and i did following things to resolve it.
i referred to https://developer.android.com/studio/build
and copy / pasted these following lines before apply plugin lines
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:4.0.0'
}
}
module app build.gradle file
apply plugin: 'com.android.application'
model{
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig.with {
applicationId "com.iamsafe"
minSdkVersion 15
targetSdkVersion 23
}
buildTypes {
debug {
minifyEnabled = false
useProguard = true
proguardFiles.add(file('proguard-rules.txt'))
}
}
}
}
dependencies {
compile 'com.android.support:support-v4:23.0.2'
compile files('libs/asmack-android-8-0.8.10.jar')
compile files('libs/commons-io-2.0.1.jar')
compile files('libs/httpclient-osgi-4.2.1-sources.jar')
compile files('libs/httpcore-4.3.2.jar')
compile files('libs/httpmime-4.1.2.jar')
}
project build.gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.10'
}
}
allprojects {
repositories {
jcenter()
}
}
In this case of issues check below code
dependencies {
classpath 'com.android.tools.build:gradle:**1.5.0**'
}
and gradle-wrapper.properties inside your project directory check below disctributionUrl:
distributionUrl=https\://services.gradle.org/distributions/gradle-2.9-all.zip
If these are not compatible with each other then you end up in this issue.
For com.android.tools.build:gradle:1.5. you need a version at least 2.8 but if you switch to a higher version like com.android.tools.build:gradle:2.1.0 then you need to update your gradle to 2.9 and above this can be done by changing distributionUrl in gradle-wrapper.properties to 2.9 or higher as below
distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip
If you work on Windows , you must start Android Studio name by Administrator.
It solved my problem
Just make sure you put the http and https proxy correctly when you create the app
I'm trying to build this old app on the newest version of Android Studio that requires Gradle 1.10. I keep getting sync errors (See below).
SYNC ERROR:
Gradle sync failed: Unsupported method: SyncIssue.getMultiLineMessage().
The version of Gradle you connect to does not support that method.
To resolve the problem you can change/upgrade the target version of Gradle you connect to.
Alternatively, you can ignore this exception and read other information from the model.

What versions/numbers should I have in my lines that are marked with ***.
buildscript {

Kept getting this error when I tried to import a file for a class I'm taking. Several days of digging and a little luck later, learned about gradle versions and Android Gradle Plug in versions. The numbers are not the same but they must correspond as per the table in this link: https://developer.android.com/studio/releases/gradle-plugin After I got that then I had to go into the build.gradle file and change it to this. My changes are annotated
// Top-level build file where you can add configuration options common to all sub-
projects/modules.
buildscript {
repositories {
google()//Add this
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:4.1.0'//change to this
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()//add this
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
and in the griddle-wrappers.properties file change
distributionUrl=https://services.gradle.org/distributions/gradle-2.10-all.zip
to
distributionUrl=https://services.gradle.org/distributions/gradle-6.5-all.zip
If you look at the table in the link you will see that the 4.1.0 in this build.gradle file line
classpath 'com.android.tools.build:gradle:4.1.0'
matches the 6.5-all in this gradle-wrapper.properties line
distributionUrl=https://services.gradle.org/distributions/gradle-6.5-all.zip
I didn't try it but I would imagine that as long as the numbers correspond to each other on the chart then it would work even if it weren't exactly these numbers.
Hope this helps you out.
Try updating the Android Gradle plugin to the latest available version:
Change
classpath 'com.android.tools.build:gradle:1.5.0'
to
classpath 'com.android.tools.build:gradle:2.3.2'
Yes indeed - however the IDE does not seem to know the latest version. I go with the latest versions when I get this type of error but IDE creates an error message that is not useful. We know the house is on fire and ee want to how to put it out...
TL;DR: IS the only way to develop both pure Java and Android applications, is on completely different Gradle projects?
I am developing a project which includes an Android application and a Java backend (along with some other common APIs).
As an IDE I am using IntelliJ Idea.
I would like to have a single Gradle project (which will be opened on a single Idea instance), that contains all the applications as subprojects.
My problem is that in order to allow the Android plugin, I need to set it in the buildScript section in build.gradle file:
dependencies {
classpath 'com.android.tools.build:gradle:2.2.3'
}
This forces the android plugin in the entire Gradle build process, and causes errors on the pure Java subprojects (they are automatically set to be built with the Android SDK instead of the Java SDK).
A workaround I have thought of is creating two separate projects (one for Android and one for Java), export the common JARs into a local Maven repository and import it from there into the Android project.
Is there a better solution that will allow me to have all the code base in the same place?
What you are asking for is possible: you just need to move the buildscript declaration from the project to the android module.
The PROJECT build.gradle may look like this:
buildscript {
// nothing for the project
}
allprojects {
repositories {
jcenter() // you could also move this to each module
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
And the Android MODULE build.gradle may look like this:
apply plugin: 'com.android.application'
// other pluguins
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.1'
// other dependencies for the build (apt, retrolambda...)
}
}
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "my.android.app"
// additional config...
}
}
dependencies {
// your app dependencies here
}
Other modules, such as backend or web, may declare their own buildscripts with their own pluguins, repositories and dependencies.
Each project has it's own buildscript classpath
root/build.gradle
project(':java-project') {
apply plugin: 'java'
}
project(':andoid-project') {
buildscript {
dependencies {
classpath 'com.android.tools.build:gradle:2.2.3'
}
}
apply plugin: 'android'
}
I'm not an android user but perhaps you need to tweak the JavaCompile tasks on the java only projects such that the compiler is forked and uses a different javac
allprojects {
if (plugins.hasPlugin('java') && !plugins.hasPlugin('android')) {
tasks.withType(JavaCompile) {
options.fork = true
options.forkOptions.executable = '/path/to/javac'
}
}
}
I want to add Firebase to my project to use push notifications
at home I implemented it by adding this line at build.gradle (app)
apply plugin: 'com.google.gms.google-services'
and this line at my build.gradel (project):
classpath 'com.google.gms:google-services:3.0.0'
and it worked .
At work for proxy reasons i'm not able to connect to jcenter and getting this error :
Unknown host 'jcenter.bintray.com'. You may need to adjust the proxy settings in Gradle.
so i cant build the project
I need a way to implement this without the plugin and classpath
I'm using
compileSdkVersion 23
buildToolsVersion "23.0.3"
my depndecies :
dependencies {
compile 'com.google.firebase:firebase-core:9.0.0'
compile 'com.google.firebase:firebase-messaging:9.0.0'
compile 'com.google.android.gms:play-services:9.6.1'
}
And is there a way to add the play-services classes to the gradel cash to be able to work offline
NOTE:
I have tried to update to sdk 24 and build tool 24.0.3
and not use thouse tow lines but i kept geting the error that fire base was never initialized and i need to use this:
firebase.initializeApp(context)
I did use in the application context but did not work
NOTE 2 :
My build.gradel (project) has jcenter as a repository
repositories {
jcenter()
}
Add below code in build.gradle(project)
repositories {
jcenter()
}
I want to install android library project to local maven repository.
Here is build.gradle:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.5.+'
}
}
apply plugin: 'android-library'
apply plugin: 'maven'
version = "1.0.0-SNAPSHOT"
group = "com.example"
repositories {
mavenCentral()
}
android {
compileSdkVersion 18
buildToolsVersion "17.0.0"
defaultConfig {
minSdkVersion 9
targetSdkVersion 18
}
}
When I run:
gradle install -i
it gets stuck here:
Executing task ':project:installTest' due to:
Task has not declared any outputs.
Starting process 'command 'd:\android-sdk-windows\platform-tools\adb.exe''. Working directory: D:\Projects\java\....... Command: d:\android-sdk-windows\platform-tools\adb.exe install -r D:\Projects\java\.......\build\apk\project.apk
An attempt to initialize for well behaving parent process finished.
Successfully started process 'command 'd:\android-sdk-windows\platform-tools\adb.exe''
> Building > :project:installTest
So first thing I noticed is that it's trying for some odd reason to deploy it on a device as APK.
Am I doing something wrong or is it just android-library plugin not compatible with maven plugin?
Edit: Please refer to the github page (https://github.com/dcendents/android-maven-gradle-plugin) for the latest instructions and find the correct version to use. The original instructions are not suitable anymore with the latest gradle release.
Original Post:
I've modified the maven plugin to be compatible with android library projects. See the project on github: https://github.com/dcendents/android-maven-gradle-plugin
Configure your android library projects to use it:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.github.dcendents:android-maven-plugin:1.0'
}
}
apply plugin: 'android-library'
apply plugin: 'android-maven'
Then you should be able to install aar into your local maven repository using the install task.
Hope this helps, if you find issues with the plugin please let me know on github and I'll fix it.
Elaborating on CyclingSir's answer, I propose to add a separate "installArchives" task. This should also take care of picking up your custom artifacts (e.g. sources).
apply plugin: 'maven'
task installArchives(type: Upload) {
description "Installs the artifacts to the local Maven repository."
configuration = configurations['archives']
repositories {
mavenDeployer {
repository url: repositories.mavenLocal().url
}
}
}
Note that with Gradle Android plugin v0.5.5, gradle install still tries to install something on a device.
There's an easier solution if you don't want to use a custom plugin. Instead, just recreate the install task with a different name. I called it installArchives. Add the following code to your build.gradle:
task installArchives(type: Upload) {
description "Installs the artifacts to the local Maven repository."
repositories.mavenInstaller {
configuration = configurations.default
pom.groupId = 'my.group'
pom.artifactId = 'my-artifact'
pom.version = '1.0.0'
}
}
You can now run gradle installArchives to install your aar locally.
UPDATE 2014-11-26
The answer below made sense at the time of writing, when Android Build Tools were at version 0.5.5. It is most likely outdated now and probably does not work anymore.
I have personally switched my projects to use android-maven-plugin as described in the answer above, the plugin works fine with the recent versions of Android Build Tools too.
THE ORIGINAL ANSWER FROM FEBRUARY 2014
Publishing as AAR
If you don't mind using an older version of com.android.tools.build:gradle (i.e. 0.5.4), you can use the approach described in this blogpost. Not that according to the discussion in adt-dev mailing-list, this does not work in 0.5.5.
Add the following lines to your build.gradle:
apply plugin: 'maven-publish'
// load bundleRelease task
// this will not load the task in 0.5.5
android.libraryVariants
publishing {
publications {
maven(MavenPublication) {
artifact bundleRelease
}
}
}
To publish to your local maven repo, call this command:
gradle publishToMavenLocal
Publishing as JAR
If your Android Library does not have custom resources and can be published as JAR, then you can use the following build.gradle that works even with 0.5.5.
// build JAR file
task androidReleaseJar(type: Jar, dependsOn: assembleRelease) {
from "$buildDir/classes/release/"
}
apply plugin: 'maven-publish'
publishing {
publications {
maven(MavenPublication) {
artifact androidReleaseJar
}
}
}
To publish to your local maven repo, call this command:
gradle publishToMavenLocal
I just solved the issue by defining an upload archive as described here:
Gradle documentation 52.6.2. Deploying to a Maven repository
uploadArchives {
repositories {
mavenDeployer {
repository(url: "file://${System.env.HOME}/.m2/repository/")
}
}
}
calling
gradle uploadArchives
deploys the artefact to the (in my case local) Maven repo.
I havn't found a simple and more flexible way to specify the local repo's url with e.g. mavenLocal() yet but the above suits my needs.
