--------------------------------------
Thanks [~revans2]!
> adjust checkstyle configurations to decrease violations
> -------------------------------------------------------
>
> Key: STORM-2510
> URL: https://issues.apache.org/jira/browse/STORM-2510
> Project: Apache Storm
> Issue Type: Bug
> Components: build
> Affects Versions: 2.0.0
> Reporter: Erik Weathers
> Assignee: Erik Weathers
> Fix For: 2.0.0
>
> Attachments: update-all-pom-violations.bash,
> update-pom-violations.bash
>
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> Adjust Storm's checkstyle configuration:
> * 4-space indent instead of 2-space indent that is default with
> google_checks.xml
> ** More hand-written code in Storm is 4-space indented than 2-space indented.
> * exclude the thrift generated code from checkstyle
> ** since we shouldn't be touching it anyways
> * go with 120 character line-length limits instead of the default of 100 from
> google_checks.xml
> ** This cuts ~70% of the line-length violations. We might wanna increase it
> even more. 140 would cut out ~90% of the line-length violations.
> With those adjustments, the total number of violations will shrink by
> ~100,000 (~140,000 -> ~40,000).
> We can decrease the existing violations even more if we upgrade the
> checkstyle version from 6.11.2 to 7.7. I figured this out after noticing
> that IntelliJ had different (& fewer) violations when I ran the checkstyle
> plugin on the same module in IntelliJ as compared to with cmdline maven. A
> further benefit of the newer checkstyle version is that it runs *way* faster.
> As in ~6+ times faster.
