Julian Hyde updated CALCITE-484:
--------------------------------
Fix Version/s: 1.0.0-incubating
> Heal incremental maven compilation: each mvn install rebuilds the whole thing
> -----------------------------------------------------------------------------
>
> Key: CALCITE-484
> URL: https://issues.apache.org/jira/browse/CALCITE-484
> Project: Calcite
> Issue Type: Bug
> Affects Versions: 1.0.0-incubating
> Reporter: Vladimir Sitnikov
> Assignee: Julian Hyde
> Labels: newbie
> Fix For: 1.0.0-incubating
>
>
> Currently the jar files are rebuild even if the source files were not
> modified.
> It would be nice to eliminate unnecessary work from the build.
> The list of bad plugins is:
> 1) maven-resources-plugin. It always regenerate files above files from
> velocity templates.
> 2) git.properties -- we might not need the exact build timestamp for dev
> builds
> 3) generate-fmpp-sources -- seems to regenerate the same parser again and
> again
> 4) hydromatic-resource-maven-plugin seems to regenerate the same
> runtime for each execution
> 5) org-apache-calcite-jdbc.properties includes build.timestamp
> If I "disable" those plugins, the subsequent builds take 6-7 seconds
> and the jars are not updated.
> Total time: 6.237 s
> Most time consuming are:
> 1.4s Calcite
> 1.2s Calcite Ubenchmark
> 0.9s Calcite Plus
> 0.8s Calcite Core
> 0.6s Calcite Spark
