-------------------------------------
Summary: Configure fmpp-maven-plugin for incremental build
Key: DRILL-1721
URL: https://issues.apache.org/jira/browse/DRILL-1721
Project: Apache Drill
Issue Type: Sub-task
Components: Tools, Build & Test
Affects Versions: 0.7.0
Reporter: Aditya Kishore
Assignee: Aditya Kishore
The [FreeMarker Pre Processor maven plugin|
https://code.google.com/p/freemarkerpp-maven-plugin/], used in {{exec/Java
Execution Engine}} module recompiles the templates every time, irrespective of
whether they have changed or not since the last build, generating fresh Java
sources which further triggers {{javac}} compilation.
Fixing this will improve the incremental compilation by shaving off close to 2
minutes of build time which would be a good win.
We will have to modify the {{fmpp-maven-plugin}} code. I had attempted this in
past and a patch may be somewhere in the stash.
