Already Defined Error when building with gradle

问题

I imported an old project from ANT to Gradle. I included all libraries and tride build but i have problem:

 E:\gradle\DriverClient\app\build\intermediates\exploded-aar\com.google.android.gms\play-services-wallet\7.8.0\res\values\wallet_colors.xml
    Error:(2) Attribute "titleTextStyle" has already been defined
    Error:(2) Attribute "subtitleTextStyle" has already been defined
    Error:(2) Attribute "divider" has already been defined
    Error:(2) Attribute "background" has already been defined
    Error:(2) Attribute "backgroundSplit" has already been defined
    Error:(2) Attribute "navigationMode" has already been defined
    Error:(2) Attribute "displayOptions" has already been defined
  .............................

I do not understand what is wrong. Here are my Gradle dependencies -

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar'
    compile 'com.larswerkman:HoloColorPicker:1.5'
    compile 'com.google.android.gms:play-services:7.8.0'
    compile 'org.jsoup:jsoup:1.8.3'
    compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.4'
}

回答1:

You can't use appcompat library and ActionBarSherlock together because they are using the same attrs.

I suggest you using the appcompat library since abs was deprecated about two years ago,not updated and out of mantenaince.

回答2:

Try to remove

compile 'com.google.android.gms:play-services:7.8.0'

Hope it helps :)
