It looks like some dependency needs org.jacoco:org.jacoco.agent:0.7.5.201505241946 as a dependency, but can't find it for some reason. It can be found in the maven repository side so it does exist. Add this line: compile group: 'org.jacoco', name: 'org.jacoco.agent', version: '0.7.5.201505241946' to your dependencies list, so it will look like this:

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile group: 'org.jacoco', name: 'org.jacoco.agent', version: '0.7.5.201505241946'
    compile 'com.android.support:appcompat-v7:24.2.0'
    compile 'com.android.support:design:24.2.0'
    compile 'com.squareup.retrofit2:retrofit:2.1.0'
    compile 'io.reactivex:rxandroid:1.0.1'
    compile 'com.squareup.retrofit2:retrofit-adapters:2.1.0'
    compile 'com.squareup.retrofit2:converter-gson:2.1.0'
    compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'
    compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile 'com.google.android.gms:play-services-maps:9.4.0'
    compile 'com.google.android.gms:play-services-gcm:9.4.0'
}

This will add the dependency to your project and cut out the middle man so to speak.

For me it happened because android studio actually entered offline mode somehow. After disabling offline mode (Settings->Build, Execution, Deployment-> Gradle-> Offline work) dependency was successfully retrieved.
