Best Regards, Vyacheslav D.

[Mmuzaf]

Vyacheslav,

Thank you for your interest in making Ignite coding style better.

The short answer is - there are no different checkstyle
configurations. One for the JetBrains Inspections, and one the
Checkstyle plugin. This is a completely different approach for
checking the Ignites source code.

Currently, we have two different configurations for the JetBrains IDEA
Inspection check:
 - ignite\.idea\inspectionProfiles\Project_Default.xml - this is
default on the IDE level and used silently by every developer whos
checkout Ignite project (it remains)
 - ignite\idea\ignite_inspections_teamcity.xml - this is the
configuration of the inspection for the TC suite (it will be deleted)
It's unobvious to maintain both of them. Previously we've planned to
fix all the inspection rules one by one and add them one by one to the
TC inspection configuration file (something like storing the
intermediate result), but it didn't happen cause the inspection TC
suite got broken after migration to 2018 version.

Now it seems to me, that it is better to use the best open source
practices like checkstyle plugin (380K usages on github repositories)
rather than proprietary software. So, we will:
 - keep IDE level inspection configuration (the Project_Default.xml config);
 - add a new checkstyle plugin configuration file (checkstyle.xml
config) which will be used simultaneously for checking code style on
build procedure and for the IDE-checkstyle plugin;

Best Regards, Vyacheslav D.

[daradurvs]

Maxim, I merged your changes to master.

Also, I've created a new build plan "Check Code Style" on TC [1] and
included in RunAll build.
The report of check-style attaches in artifacts once build is finished.

Please check that it works as expected once again and announce new
requirements in a separate thread to avoid confusion of community.

cc Petr, Pavel (JFYI)

This is quite strange error, in case of "install" phase it'd be better

[vveider]

Vyacheslav, can you check this build please [1] if everything was ran as expected?

Also I still strictly against adding checkstyle to project build as minor issues in checkstyle should not be blocker for test run.

[Nikolay Izhikov-2]

Hello, Petr.

The main issue here is - we, as a community, still think that issue with code style is "minor".
Personally, I think there is no "minor" issues with code style - we should force single code style as hard as we can.

I think we *must* fail entire build if there are code style issues.

[Nikolay Izhikov-2]

Hello, Igniters.

1. I've added "EmptyLineSeparator" inspection, according to our code style
[1]
2. I've fixed all current code style violations.

Please, see my commit [2]

You may want to merge these changes to your private repos.

[Ivan Pavlukhin]

Hi Nikolay,

Great, another one nice step to clean code.

I scrolled down the commit [1] and have couple of observations:
1. According to our code style agreements each class member should be
separated by 1 empty line. As I see there were many places where it
was not followed for class fields. E.g. empty lines were added for a
code snippet below. For me fields without extra empty lines between
them look fine. Of course, it is a question of our agreements. So, we
can either permit no empty lines for fields or enforce empty line for
each class member.
private static class FlaggedCacheOperationCallable implements
Callable<GridRestResponse>, Serializable {
/** */
private static final long serialVersionUID = 0L;
/** */
private final String cacheName;
/** */
private final Set<GridClientCacheFlag> cacheFlags;

2. Also I noticed an empty line between a method signature and a first
statement in the method in some places, e.g. [2]. Can/should we
enforce no empty lines there?

And one aside observation (in the same file), it has class fields
without a javadoc [3]. Do not our code check jobs enforce javadoc for
fields?

Hello, Ivan.

> For me fields without extra empty lines between them look fine.

This is violation of Ignite code style, so we should fix it for now.
If we decide to change code style, we can change check.

You can look into checkstyle documentation for it.
For now, I don't know about such checks.
