             Summary: Migrate build system to Gradle
                 Key: CALCITE-2905
                 URL: https://issues.apache.org/jira/browse/CALCITE-2905
             Project: Calcite
          Issue Type: Improvement
    Affects Versions: 1.18.0
            Reporter: Vladimir Sitnikov


Current build system has quirks, and it has well-known limitations.

 

For instance:

1) If you change code in "core" and or "linq4j" modules and you want to check 
"cassandra", you need to "mvn install" those modules first otherwise 
"cassandra" would use "core" from the local Maven repository

2) If you want to see how Calcite plays together with Drill, it has to be 
multi-step as well. You can't just change some bits in Calcite and just 
build/test Drill

3) Maven builds seem to be single-threaded by default. For instance, 
checkstyle/forbiddenapis always goes before compile, and it does take time. I 
happen to disable checkstyle for local checks.

4) Maven plugins are hard to write. You can't just have a pair of classes to be 
used during the build.
