Could not determine the dependencies of task ':app:crashlyticsStoreDeobsDebug' if I enable the proguard

Question

I get following error when I was running an app within Android Studio 2.

Gradle tasks [:app:assembleDebug]
Could not determine the dependencies of task ':app:crashlyticsStoreDeobsDebug'.
> Task with path 'dexDebug' not found in project ':app'.
BUILD FAILED

Here is the build.gradle for module

buildscript {
    repositories {
        maven { url 'http://download.crashlytics.com/maven' }
        maven { url "http://dl.bintray.com/populov/maven" }
    }

    dependencies {
        classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1.+'
    }
}

apply plugin: 'com.android.application'
apply plugin: 'crashlytics'

repositories {
    maven { url 'http://download.crashlytics.com/maven' }
    maven { url "http://dl.bintray.com/populov/maven" }
    maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
}

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.2'

    defaultConfig {
        minSdkVersion 17
        targetSdkVersion 19
    }


    buildTypes {
        debug {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:23.+'
    compile 'com.crashlytics.android:crashlytics:1.+'
}

The error is gone if I set the minfyEnabled to "false". But I do want it enabled.

Here is the build.gradle in project level.

buildscript {
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-alpha3'
    }
}

allprojects {
    repositories {
        maven { url "http://dl.bintray.com/populov/maven" }
        mavenCentral()
        jcenter()
    }
}

The error is also gone if I replace "2.0.0-alpha3" to "1.3.1". But I do want "2.0.0" because I want the "Instant Run" feature.

Here is the gradle-wrapper.properties.

Does anyone know how to fix it? Thank you.

Answer 1

I had the same issue a few days ago and I found this thread Twitter Developer Forum that points to some incompatibility with versions of gradle/build-tools/crashalics.

My problem was slightly different from yours as I'm not using alpha-3 I'm using 1.5. But on my update I also changed to the latest gradle distribution gradle-2.9-all.zip.

So probably/maybe you can fix it by changing to the latest gradle version. But If it does not work, you'll really have to be patient and wait until build tools V2.0 is not in alpha anymore OR the Crashalitycs team, fix the incompatibility.
