How to resolve Duplicate Class error in Android

问题

1. I am getting Duplicate class com.google.protobuf.AbstractMessageLite found in modules jetified-protobuf-javalite-3.11.0.jar (com.google.protobuf:protobuf-javalite:3.11.0) and jetified-protobuf-lite-3.0.1.jar (com.google.protobuf:protobuf-lite:3.0.1).

2. I have not seen an answer that clears up my issue. I appreciate any assistance.

回答1:

You need to add an exclusion on one of the imports so it only adds the package once.

Example:

// Now junit will not include hamcrest library. Therefore there will be no 
//dependency conflict. 
 compile ('junit:junit:4.12'){
    exclude group: 'org.hamcrest', module:'hamcrest-core'
}
