com.android.dex.DexException: Multiple dex files define

Question

I am using Android Studio 0.4.2. Opened project from a friend who is using 0.3.2. Tried to compile but got exception.

Execution failed for task ':JuiceTV:dexDebug'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:

Tried this things:

• deleting *.apk files
• searching for dependencies with gradle -q dependencies but got nothing

JuiceTV Gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.7.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 18
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 18
    }
}

dependencies {
    compile project(':TVbase')
}

BaseTv Gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.7.+'
    }
}
apply plugin: 'android-library'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 18
    buildToolsVersion '19.0.0'

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 18
    }
}

dependencies {
    compile 'com.android.support:support-v4:18.0.+'
    compile files('libs/joda-time-2.2.jar')
    compile files('libs/mmlib.jar')
    compile files('libs/commons-io-2.4.jar')
}

Any new tips?

Answer 1

I just had the same issue and I discovered that my application and a library were referring to 2 versions of the same jar.

I did a search and my application.iml file clearly showed the duplicates.

<orderEntry type="library" exported="" name="crittercism_v3_0_11_sdkonly" level="project" />
<orderEntry type="library" exported="" name="crittercism_v4_4_0" level="project" />

I replaced the older v3 version with the v4 version and it worked after a clean rebuild.

Answer 2

This happens when a Module has a dependency on both another module and that same module's jar.
