若干问题记录

迁移完成后 gradle sync 失败 duplicate entry: META-INF/NOTICE.txt

Could not resolve all files for configuration ':app:nskst_test_wuhan_fixedDebugCompileClasspath'.
> Failed to transform file 'utils.jar' to match attributes {artifactType=processed-jar} using transform JetifyTransform
   > Failed to transform '/app/libs/utils.jar' using Jetifier. Reason: duplicate entry: META-INF/NOTICE.txt. (Run with --stacktrace for more details.) To disable Jetifier, set android.enableJetifier=false in your gradle.properties file.

解决

找到对应的jar，发现有重复文件，使用zip命令删除

$ zip utils.jar -d  META-INF/LICENSE.txt  
deleting: META-INF/LICENSE.txt
deleting: META-INF/LICENSE.txt
deleting: META-INF/LICENSE.txt
deleting: META-INF/LICENSE.txt

$ zip utils.jar -d  META-INF/NOTICE.txt  
deleting: META-INF/NOTICE.txt
