我引用compile 'com.squareup.retrofit2:converter-jackson:2.1.0'Gradle没有错误，运行APP就出了这个error。
错误日志：Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/LICENSE
解决方法如下：
android {
compileSdkVersion
buildToolsVersion "24.0.3"
defaultConfig {
applicationId "com.edwin.xxxx"
minSdkVersion
targetSdkVersion
versionCode
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
packagingOptions{
exclude 'META-INF/NOTICE' // will not include NOTICE file
exclude 'META-INF/LICENSE' // will not include LICENSE file
// as noted by @Vishnuvathsan you may also need to include
// variations on the file name. It depends on your dependencies.
// Some other common variations on notice and license file names
exclude 'META-INF/notice'
exclude 'META-INF/notice.txt'
exclude 'META-INF/license'
exclude 'META-INF/license.txt'
}
}
