slack plugin regression (global slack plugin)

[matejsp]

I have just updated to 2.11 and global slack plugin works again! No more exceptions.
However latest version now displays additional "null" text.

Before:

After:

[timja]

at a guess its this:
#448

[esproul]

I upgraded to 2.10 yesterday and notifications stopped working. I tried 2.11 this morning and still broken. Downgrading to 2.6 works. I'm running Jenkins 2.156.

I'm not familiar with how to troubleshoot plugin issues but I'm happy to help narrow it down if I can.

[timja]

what's not working? 2.11 should work fine other than the null text

[esproul]

No notifications are received in Slack. Jenkins appears to have sent them:

Dec 19, 2018 11:10:42 AM jenkins.plugins.slack.SlackNotifier perform
INFO: Performing complete notifications

If I go into a job, under Slack Notifications, and hit Test Connection, I get a message. But there is no notification from any job completion. If I downgrade the plugin, with no other changes, the notifications work.

[matejsp]

It works with (with extra null text):
Global Slack Notifier Plugin 1.3
Slack Notification Plugin 2.11
Jenkins ver. 2.156

[timja]

Can you screenshot your global config please? and job config?

[esproul]

Global settings:

Job config:

[timja]

try remove your slack compatible app url

[esproul]

Does not appear to make any difference.

I am having the same issue after updating to 2.10. Updating to 2.11 did not fix the issue, either. Test Connection works, but jobs do not trigger a message.

[timja]

@jkrehm are you using global slack notifier plugin or just slack-plugin?

[timja]

and what's the last version that works for you @jkrehm ?

[viktorkholod]

The same issue after upgrade to 2.10 and 2.11.
Jenkins 2.150.1
Slack Notification Plugin 2.11

[timja]

This issue is about null text when used with the global slack notifier plugin

Can you please create a new issue,
and provide your global config and job config, and the last version of the slack plugin that works for you please

[jkrehm]

@timja Just the slack-plugin (I was not aware of the global plugin until this thread).

I upgraded to 2.10 and then 2.11 (hoping it would fix the issue) so I am not able to drop back beyond that, but based on configuration backups, I believe 2.3 was what was in use. I'm guessing that won't be much help diagnosing the issue because of how far back it is.

[timja]

unfortunately not since 2.3 was over a year ago and lots of changes have been merged since.
does your issue look like this one?
#455

I just posted all my config there (which is working for me...) i've been trying to reproduce these issues but not sure what is causing it

[jkrehm]

Since my issue was with slack-plugin (not the global slack-plugin) #457 fixed the issue for me. Please ignore my comments above.

I had the same issue: upgraded to Jenkins version 2.150.1, slack plugin version 2.11
We use Job DSL to describe/migrate jobs and CasC to configure Slack when newer Jenkins versions appear, so this was not the issue with how jobs/slack was configured.

We never used "Notify regression" option, but I noticed that when you enable it, it starts sending the notifications again. With it disabled, any other combination of options didn't work for me. I looked into the source, and didn't find anything related to this (or maybe I looked in a wrong place). System log also showed no errors.

Solution that worked for me is to upgrade Slack plugin to 2.12, which just recently appeared in plugin manager

[esproul]

I can also confirm that 2.12 fixes the missing notification. I apologize for hijacking this issue.

To recap: I was running 2.6, which had working notifications. When upgrading to either 2.10 or 2.11, notifications were not sent.

[matejsp]

With latest version 2.13 it works without extra null. You can close the issue.
