Check if the IDL source file has changed before regenerating the Java
classes to prevent unnecessary recompilation when using maven.

> Maven Plugin Always Recompiles IDL Files
> ----------------------------------------
>
> Key: AVRO-3889
> URL: https://issues.apache.org/jira/browse/AVRO-3889
> Project: Apache Avro
> Issue Type: Bug
> Components: build, java
> Affects Versions: 1.12.0, 1.11.3, 1.11.4
> Reporter: Brian Cullen
> Priority: Minor
> Labels: pull-request-available
> Time Spent: 2h
> Remaining Estimate: 0h
>
> Currently both the TestIDLProtocolMojo (in version 1.11.x) and the IDLMojo in
> master fail to pass the source file into the compiler when calling the
> compile to destination method. This means that the IDL files are never
> registered as up to date and are always recompiled when the plugin is
> executed. The knock on effect of this is that the maven compiler plugin
> always thinks it needs to recompile the whole project which is not ideal.
> It does appear that this is a simple change to pass the source file into the
> method so that the up to date check can be preformed. I have made the change
> locally and to try it out. It appears to work but I don't know if I'm missing
> something that means this won't work in some cases.
