Using Jcenter with gradle in Android studio

Question

Edit: Figured it out, I implemented JBaruch's suggestion to the allprojects->repositories section of the project-wide build.gradle file.

I am writing a project that depends upon IOIO. Compiling IOIO's libs on my project is giving me trouble. I have tried placing the .aar and .jar files directly in my libs/ directory. However, working with .aar files in gradle is proving to be a trouble-mite. Now, I am attempting to use jcenter to find these libs.

Using jcenter as my repository, gradle originally could not resolve

com.github.ytai.ioio:IOIOLibCore

but specifying version number 5.05 fixed this. However, now gradle is failing to resolve

com.sparetimelabs:purejavacomm:0.0.22

which is not a library that I ask to be compiled with my project.

Below is a copy of my app/build.gradle file

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.example.agrc.elkausbtransfer"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
        compile 'com.android.support:appcompat-v7:23.0.1'
        compile 'com.github.ytai.ioio:IOIOLibCore:5.05'
        compile 'com.github.ytai.ioio:IOIOLibPC:5.05'
        compile 'com.github.ytai.ioio:IOIOLibAndroid:5.05'
        compile 'com.github.ytai.ioio:IOIOLibAndroidAccessory:5.05'
        compile 'com.github.ytai.ioio:IOIOLibAndroidDevice:5.05'
        /* To use IOIO from source
        compile fileTree(dir: 'libs', include: ['*.jar'])
        compile(name: 'IOIOLibAndroid-release', ebxt: 'aar')
        compile(name: 'IOIOLibAndroidAccessory-release', ext: 'aar')
        compile(name: 'IOIOLibAndroidDevice-release', ext: 'aar')
        */
    }

After trying JBaruch's suggestion and adding the maven url to my Project (root) build.gradle file, I noticed that the Gradle Build file looks as follows:

    Executing tasks: [:app:assembleDebug]

Configuration on demand is an incubating feature.

FAILURE: Build failed with an exception.

I.e., Gradle did not search at the maven url provided. How do I force Gradle to do this?

com.sparetimelabs:purejavacomm:0.0.22 is a transitive dependency of IOIO project. The problem is that Spare time labs has their own repository and doesn't publish their artifacts to Bintray. What you need to do is to add their repository to the list of your repositories in Gradle:

repositories {
    jcenter()
    maven {
       url 'http://www.sparetimelabs.com/maven2'
    }  
}

That didn't work. I'm getting the same 'Failed to resolve: com.sparetimelabs:purejavacomm:0.2.22' statement in the Messages Gradle Sync dialog. – errolflynn Sep 25 '15 at 17:16
Added that line to the allprojects repositories, the project now syncs. – errolflynn Sep 25 '15 at 17:27

buildscript {
repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:4.0.1'
    
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}
allprojects {
repositories {
    google()
    jcenter()
}
}
