[Feature] Show number of findings
It would be great if diktatCheck also prints the number of findings so if a change in config dile is done it is possible to observe the impact of the change. For example if you have a huge code base and you have a lot of findings for a specific rule and you chnages some properties in the config file for this rule it would be possible to check how many findings have been gone and if the config change was useful.
Great job so far <3
@WebTiger89, thank you for your feedback.
Could you please clarify your use-case?
Currently (versions 1.2.3 and 1.2.4-SNAPSHOT), the Maven plug-in clearly reports the number of errors upon failure, e.g.:
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 01:22 min
[INFO] Finished at: 2022-08-10T19:04:01+03:00
[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal org.cqfn.diktat:diktat-maven-plugin:1.2.3:check (diktat) on project diktat-rules: There are 8 lint errors -> [Help 1]
[ERROR]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR]
[ERROR] For more information about the errors and possible solutions, please read the following articles:

This is clearly visible from the console:

as well as from the IDE:

Additionally, when using CLI, passing the -v/--verbose switch to ktlint enables reporting the number of errors, too:
$ ktlint --color -v -R diktat.jar --disabled_rules=standard '**/*.kt'
src/main/kotlin/com/example/C.kt:8:1: [WRONG_INDENTATION] only spaces are allowed for indentation and each indentation should equal to 4 spaces (tabs are not allowed): expected 12 but was 16 (diktat-ruleset:indentation)
19:16:59.549 [main] DEBUG com.pinterest.ktlint.internal.KtlintCommandLine - 1223ms / 1 file(s) / 1 error(s)
Also - may be we will show the number of warnings also in Benedi.kt, @0x6675636b796f75676974687562 ?
@akuleshov7, Benedi.kt already does that.
First, the Action displays the summary one-liner once it completes:

Additionally, the detailed information is available from the Checks tab (both pull requests and commits):
