Execution failed for transformClassesWithJarMergingForDebug'. (Volley)

问题

I am trying to build my app on android studio virtual simulator, I have successfully tested on api level 21 and above now I am testing lower level api 19, but whenever I run i will get this error:

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.

com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/android/volley/Request$Priority.class

This is my gradle file:

 apply plugin: 'com.android.application'

android {
compileSdkVersion 25
buildToolsVersion "25.0.0"
defaultConfig {
    minSdkVersion 15
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}
repositories {
mavenCentral()
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'

}

I have found many solution online regarding this but not specifically to this issue, I believe the problem is with volley, but I cannot remove any library due to my code. How should I solve this issue? Thank you!

回答1:

You are using 2 different versions of volley libraries

 compile 'com.android.volley:volley:1.0.0'
 compile 'com.mcxiaoke.volley:library:1.0.19'

use any one of the above

and I dont know about

compile 'dev.dworks.libs:volleyplus:0.1.4'

If that is similar library to above two ,the error will still remain
