Answer 1

Try to prevent play services to obfuscate form proguard.

-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.**

Issues:

From your log file, it is clear that

1. Some Jars are not available
2. Some unresolved references are there.

---

Solution:

If you use maven and eclipse then, you need to run this following command

mvn eclipse:clean

mvn eclipse:eclipse

For gradle and Android studio,

gradlew is not in your global path. To execute the 'clean' task (or any task for that matter) using the gradle wrapper (gradlew) in your project directory in your terminal, specify the current directory with the './':

./gradlew clean

For gradle and eclipse:

gradle clean build
gradle eclipse

Resource Link:

1. Java Project + Gradle + Eclipse Integration Example

To show the jars in build.gradle

task listJars << {
    configurations.compile.each { File file -> println file.name }
}

Output of gradle -q listJars

> gradle -q listJars
