Failing to include libraries by Maven to Android studio
android, android-studio, gradle, intellij-idea, maven
Solution
What resolved the problem was the same as suggested in this question I changed the `repositories` tag to:
repositories {
mavenCentral()
jcenter {
url "http://jcenter.bintray.com/"
}
}
Problem
I have a project which I want to change to use Maven to include the libraries for OSMDroid instead of local dependencies. According the OSM Droid tutorial I need to include the following dependencies: ``` dependencies { compile 'org.osmdroid:osmdroid-android:4.2' compile 'org.slf4j:slf4j-simple:1.6.1' } ``` And from this SO post I need to add a line to be able to use Maven through the gradle: ``` repositories { mavenCentral() } ``` That makes my basic build.gradle for Module: app to this: ``` apply plugin: 'com.android.application' android { compileSdkVersion 21 buildToolsVersion "21.1.1" defaultConfig { applicationId "se.einarsundgren.anApp" minSdkVersion 14 targetSdkVersion 21 versionCode 1 versionName "1.0" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } repositories { mavenCentral() } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:appcompat-v7:21.0.3' compile 'org.osmdroid:osmdroid-android:4.2' compile 'org.slf4j:slf4j-simple:1.6.1' } ``` This results in the errors from Gradle sync: ``` Error:(29, 13) Failed to resolve: org.slf4j:slf4j-simple:1.6.1 Error:(28, 13) Failed to resolve: org.osmdroid:osmdroid-android:4.2 ``` This is the error I get from Gradle build when I try to compile: ``` Error:A problem occurred configuring project ':app'. > Could not resolve all dependencies for configuration ':app:_debugCompile'. > Could not resolve org.osmdroid:osmdroid-android:4.4. Required by: Mappish:app:unspecified > Could not GET 'https://jcenter.bintray.com/org/osmdroid/osmdroid-android/4.4/osmdroid-android-4.4.pom'. > peer not authenticated > Could not GET 'https://repo1.maven.org/maven2/org/osmdroid/osmdroid-android/4.4/osmdroid-android-4.4.pom'. > peer not authenticated > Could not resolve org.slf4j:slf4j-simple:1.6.1. Required by: Mappish:app:unspecified > Could not GET 'https://jcenter.bintray.com/org/slf4j/slf4j-simple/1.6.1/slf4j-simple-1.6.1.pom'. > peer not authenticated > Could not GET 'https://repo1.maven.org/maven2/org/slf4j/slf4j-simple/1.6.1/slf4j-simple-1.6.1.pom'. > peer not authenticated ``` This might be an easy error since I'm a newbie both to Maven and to the details of Gradle. But I have no idea why this is not working.
