----------------------------------

             Summary: Specific Avro compiler does not annotate generated Builder class with AvroGenerated
                 Key: AVRO-2298
                 URL: https://issues.apache.org/jira/browse/AVRO-2298
             Project: Apache Avro
          Issue Type: Bug
          Components: java
    Affects Versions: 1.8.2
            Reporter: Olli Salonen


According to current [AvroGenerated documentation|[https://avro.apache.org/docs/1.8.2/api/java/org/apache/avro/specific/AvroGenerated.html],]
{quote}All Avro generated classes will be annotated with this annotation.
{quote}
However, the nested Builder class that the specific Avro compiler generates does not get annotated with AvroGenerated or any user specified javaAnnotations. The Builder template is missing annotation generation as can be seen in the [template file on Github|[https://github.com/apache/avro/blob/7ed38d7c7e150987ef8bf035196576fc158e03eb/lang/java/compiler/src/main/velocity/org/apache/avro/compiler/specific/templates/java/classic/record.vm#L296].]

This has implications for tools relying on Generated annotations, such as test coverage tools like JaCoCo, which can ignore the generated SpecificRecord class but not the nested SpecificBuilder class as a result. [Here is one JaCoCo bug describing the issue|https://github.com/jacoco/jacoco/issues/814].
