----------------------------------------
Summary: Gora 0.4 compiler crash with "enum" type
Key: GORA-331
URL: https://issues.apache.org/jira/browse/GORA-331
Project: Apache Gora
Issue Type: Bug
Components: gora-compiler
Affects Versions: 0.4, 0.5
Reporter: Damien Raude-Morvan
As part of my work on GORA-199 I've updated some Dictanova projects to 0.4
release (more precisly to 0.5-SNAPSHOT) for testing.
Unfortunelly, I've detected that Gora Compiler crash if there is an "enum" type
field inside a record.

{
"name": "RecordWithEnum",
"namespace": "com.drazzib.com",
"type": "record",
"fields": [
{
"name": "type",
"type": {
"name": "MyEnum",
"type": "enum",
"symbols": [
"PERIOD",
"INSTANT"
]
}
}
]
}
{noformat}
If you try to compile this schema with Gora 0.4, you'll get the following error
:

I've managed to workaround this problem by simply dropping avro enum.vm inside
gora source.
