Nicolas created AVRO-2940:
-----------------------------
Summary: Add velocity template overrides to maven plugin
Key: AVRO-2940
URL: https://issues.apache.org/jira/browse/AVRO-2940
Project: Apache Avro
Issue Type: Improvement
Components: java
Reporter: Nicolas
h3. Context
In my team, we are exploring creating java classes for our internal teams with
additional customizations like adding annotations to the output java class from
.avsc. To do this, we have modeled off of the maven-plugin module.
Ultimately we needed to create a custom record.vm template and set our own
templateDirectory in the classpath of our custom wrapping jar.
{code:java}
final SpecificCompiler compiler = new SpecificCompiler(protocol);
compiler.setTemplateDir(templateDirectory); {code}
h3. Problem
Even though we are only overriding a subset of the velocity templates, we are
copy pasting all of the templates from the compiler module. The
SpecificCompiler class can only handle a single directory and assumes we can
just append
{code:java}
templateDir + "<template>.vm" {code}
h3. Idea for improvement
I am wondering if it's worth exploring having users of the compiler take a list
of directories. We can use the ordering to determine the priority of the
template so that users like me could provide our local directory at the head
with only our overrides present.
