----------------------------------
Summary: generated avro sources not cleaned up or re-created after changes
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.
