Adding a Maven dependency (XML) on a Android Studio project - maven

Question

I'm trying to use this Java library in my Android app. From the documentation, I have to put compile "json-to-pdf:json-to-pdf:0.7.5" in my build.grade dependencies. When I try to sync the project, I get an error:
Error:(39, 13) Failed to resolve: json-to-pdf:json-to-pdf:0.7.5
I asked the owner, but he does not know how to fix it. I think I have to add the following Maven dependencies in build.grade too:
<repositories>
<repository>
<id>clojars.org</id>
<url>http://clojars.org/repo</url>
</repository>
</repositories>
But I dont't know how to do that.
Here is my settings so far:
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
compileOptions.encoding = 'ISO-8859-1'
defaultConfig {
applicationId "br.com.app"
minSdkVersion 14
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
repositories {
jcenter()
//mavenCentral() I tried that but doesn't work
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.1'
...
compile 'json-to-pdf:json-to-pdf:0.7.5' // Doesn't work
}

Answer 1

You have to define the clojars Maven repository in your build.gradle.
repositories {
jcenter()
maven {
url 'http://clojars.org/repo'
}
}
The author of this library should probably add this to the GitHub readme.
Update: I responded to the GitHub issue with the appropriate Gradle snippet that should be added to the docs.
