com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK error_prone/Annotations.gwt.xml

解决方法
经过三个小时的挣扎得到了这个解决方案：将这些线加入
packagingOptions {
exclude 'error_prone/Annotations.gwt.xml'
exclude 'third_party/java_src/error_prone/project/annotations/Annotations.gwt.xml'
exclude 'third_party/java_src/error_prone/project/annotations/Google_internal.gwt.xml'
}
最后 ：
packagingOptions {
exclude 'meta-inf/DEPENDENCIES.txt'
exclude 'meta-inf/LICENSE.txt'
exclude 'meta-inf/NOTICE.txt'
exclude 'meta-inf/NOTICE'
exclude 'meta-inf/LICENSE'
exclude 'meta-inf/DEPENDENCIES'
exclude 'meta-inf/notice.txt'
exclude 'meta-inf/license.txt'
exclude 'meta-inf/dependencies.txt'
exclude 'meta-inf/LGPL2.1'
