please advise. I'm not sure why TeamCity build fails

[Aleksey Kurinov]

Hi guys

Please help me to understand the TeamCity test failing problem.

I created a pull request and TeanCity failed.

As part of the problem investigation I've created a new pull request with minor code change to check how TeamCity would test this minor change. I've just added a comment line. 

Team city test has failed again and I'm not sure why it happens.

pull request is https://github.com/apache/ignite/pull/8105 

https://ci.ignite.apache.org/buildConfiguration/IgniteTests24Java8_RunBasicTests/5502960?buildTab=overview

errors are following:

#9445:

Unexpected error during build messages processing in TeamCity

  Unexpected error occurred during build message processing in TeamCity, please contact your system administrator

  Intermediate data was not removed and can be found at /opt/buildagent/temp/buildTmp/inspection689365797700297143result

#24031

btw my original pull request is https://github.com/apache/ignite/pull/7977

thank you,

Aleksei

Hi Aleksey!

Apache Ignite is pretty complex thing with huge amount of different tests in several languages. So some of them will fail time to time and it considered normal (at least right now).
To verify your PR you could take an advantage of Apache Ignite Teamcity Bot [1]. It will check result of RunAll (<— it’s a TeamCity RunAll task [2]) of your changes agains result of master and build a report. The most interest part of this report is a "Possible blockers" section. There will be tests that pass on master branch and fail with your changes. All those blockers require investigation and almost often has to be fixed (however, it is possible that these tests were failed in master branch too, so it's a good idea to check it first).

So the possible steps to verify your changes is following:
1) push the changes and create PR
2) go to the Apache Ignite Teamcity Bot [1] page and press the "Inspect contribution" button.
3) select the "apache" tab if it is not selected
4) find your PR by it's number and hit the "More" button and then hit the "Trigger build" button
5) now you have to wait until TC build is finished
6) finally the "Show pull/XXXX/head report" button will appear

Some information about Apache Ignite Teamcity Bot you could find here [3]. It obsolete a little but still may be useful.
