That would make sense and I was going that way at first. It is spread over
some of the project files though and there was something about eclipse having
problems with it (although the last time, we tried, using eclipse for
developing Flink didn't work anymore).
So in the end, changing this may be more beautiful but we don't really gain
much by it, do we? Only, potentially, some problems.

> Key: FLINK-7166
> URL: https://issues.apache.org/jira/browse/FLINK-7166
> Project: Flink
> Issue Type: Bug
> Components: Build System
> Affects Versions: 1.4.0
> Reporter: Nico Kruber
> Assignee: Nico Kruber
>
> Since the AVRO upgrade to 1.8.2, I could compile the flink-avro module any
> more with a failure like this in {{mvn clean install -DskipTests -pl
> flink-connectors/flink-avro}}:
> {code}
> Compilation failure
> [ERROR]
> flink-connectors/flink-avro/src/test/java/org/apache/flink/api/io/avro/generated/Fixed16.java:[10,8]
> org.apache.flink.api.io.avro.generated.Fixed16 is not abstract and does not
> override abstract method readExternal(java.io.ObjectInput) in
> org.apache.avro.specific.SpecificFixed
> {code}
> This was caused by maven both not cleaning up the generated sources and also
> not overwriting them with new ones itself. Only a manual {{rm -rf
> flink-connectors/flink-avro/src/test/java/org/apache/flink/api/io/avro/generated}}
> solved the issue.
> The cause for this, though, is that the avro files are generated under the
> {{src}} directory, not {{target/generated-test-sources}} as they should be.
> Either the generated sources should be cleaned up as well, or the generated
> files should be moved to this directory which is a more invasive change due
> to some hacks with respect to these files.
