Gradle Build Android Project “Could not resolve al

Question

I'm trying to build my first project with Gradle and I think my gradle files and settings are correct.

I'm using only one module and Support V4 + AppCompatBar libraries.

Project - build.gradle

allprojects {
    repositories {
        mavenCentral()
    }
}

Project - settings.gradle

include ':AssignmentTempos21'

Main module - build.gradle

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 17
    }
}

dependencies {
    compile "com.android.support:support-v4:18.0.+"
    compile "com.android.support:appcompat-v7:18.0.+"
}

Console output with -i flag:

Answer 1

compileSdkVersion 17
targetSdkVersion 17

change the compile version from 18 to 17

compile "com.android.support:support-v4:17.0.+"
compile "com.android.support:appcompat-v7:17.0.+"

Answer 2

I had this message in Android Studio 2.1.1 in the Gradle Build tab. I installed a lot of files from the SDK Manager but it did not help.

I needed to click the next tab "Gradle Sync". There was a link "Install Repository and sync project" which installed the "Android Support Repository".

Answer 3

Add this to your gradle:

allprojects {
    buildscript {
        repositories {
            maven {
                url "https://dl.bintray.com/android/android-tools"
            }
        }
    }
...
}

Answer 4

As Peter says, they won't be in Maven Central

from the Android SDK Manager download the 'Android Support Repository' and a Maven repo of the support libraries will be downloaded to your Android SDK directory (see 'extras' folder)

to deploy the libraries to your local .m2 repository you can use maven-android-sdk-deployer

2017 edit:

you can now reference the Google online M2 repo

repositories {
google()
jcenter()
}

Answer 5

1. Install android sdk manager
2. check if building tools installed. install api 23.
3. from the Android SDK Manager download the 'Android Support Repository'
4. remove cordova-plugin-android-support-v4
5. build

Answer 6

to echo @friederbluemle, you can also just launch the SDK manager from the command line if you have the Android SDK tools installed:

$ android

and then in the UI that pops up, select the tools/repositories that need to be installed -- in your case the support library repo
