File1: E:\androidstudio\DiDiRepairCar\app\libs\AMap3DMap_5.7.0_AMapNavi_5.6.0_AMapSearch_5.7.0_AMapLocation_3.7.0_20180109.jar

File2: C:\Users\Administrator\.gradle\caches\modules-2\files-2.1\com.alibaba\fastjson\1.2.9\3a6e5f623dccd587c3d3cffd4fde80261f326715\fastjson-1.2.9.jar

以上原因由於高德的jar包和fastjson的jar包 出現了相同的檔案META-INF，導致無法合併檔案。

解決辦法：找到兩個jar包下的相同檔案然後在gradle裡面新增如下程式碼，然後clean專案，重新執行。

packagingOptions {
    exclude 'META-INF/maven/com.alibaba/fastjson/pom.properties' 相同檔案的名稱exclude 'META-INF/NOTICE.txt' // will not include NOTICE file
exclude 'META-INF/LICENSE.txt' // will not include LICENSE file
 
exclude 'META-INF/MANIFEST.MF'
exclude 'META-INF/maven/com.alibaba/fastjson/pom.xml'
