Jenkins version: 2.107.2
Bitbucket PR builder plugin version: 1.4.26
I am trying to setup a Bitbucket PR buider, but my Job is not getting triggered when a new PR is created (or) when the comment "test this please" is updated in the open PR. Here's my config:
I see a below NullPointerException in the jenkins logs # /var/log/jenkins/jenkins.log.

Any help on this is much appreciated. Let me know what I am missing here.

We've recently noticed our Jenkins builds stopped getting triggered automatically. After further investigation there were numerous issues.
Github webhooks were unsuccessful with Github reporting "Couldn't connect to the server" in Github's webhook configuration UI. I can confirm our ELB and EC2 instance hosting Jenkins is live and healthy. No DNS changes have been made here.
Jenkins logs report various failures:
Invalid credentials despite having a valid Jenkins username & password credentials (password is a personal API token):
There is no credentials with admin access to manage hooks on GitHubRepositoryName[host=github.com,username=REDACTED,repository=REDACTED]
Failed to delete post-commit hook:
ALPN callback dropped: SPDY and HTTP/2 are disabled. Is alpn-boot on the boot class path?

We've configured the following Jenkins plugins:
Git Plugin
Github Organizations with Github Branch Source with https://support.cloudbees.com/hc/en-us/articles/224543927-GitHub-webhook-configuration
I've followed all the troubleshooting steps at https://support.cloudbees.com/hc/en-us/articles/224621648-GitHub-webhook-troubleshooting but I'm getting no where. Steps that fail:
A.2. I tried redelivering the webhook payload but get Couldn't connect to server
B.4 Displays lists of Failed to delete post-commit hook:, Failed to create hook
, and There is no credentials with admin access to manage hooks on GitHubRepositoryName[host=github.com,username=REDACTED,repository=REDACTED]
What Does Work
Able to scan organization
Able to trigger builds manually by using Build Now
There seems like there are so many issues I have no idea where to look next. Thank you for help in advance.
Looks like our AWS Security Group was white-listing Github Hook IP addresses (https://api.github.com/meta) and Github recently added or changed an IP address that was not in the Security Group. So our AWS Security Group was rejecting requests. We added refreshed the IP addresses and it now works.

I am trying to run my Java Dataflow with the DataflowRunner on GCP.
Dataflow works fine with DirectRunner but when changing to DataflowRunner and running it, the console starts staging the files and I suddenly I get the following error several times:

But the staging continues (as the console still outputs some staging info) and at some point the errors pops again (may be for the 5th time) and then the following:
mars 19, 2018 8:48:13 PM org.apache.beam.runners.dataflow.util.PackageUtil stageClasspathElements
INFOS: Still staging 127 files
As the console says that it is still staging and don't understand whether this is staging issue or related to the execution of my code...
Any idea about it and how to solve this?
** EDIT **
There is another error that I didn't notice before:

This was actually a networking issue. Workaround solution is to deploy the pipeline through a Compute Engine instance. This will assure you a good network bandwidth.
We had installed Jenkins couple of weeks back when we migrated from one server to another, which was working fine.
We later migrated our jobs with same name like previous job in old jenkins and installed plugins needed. They were also working fine.
Later placed one job’s config.xml and restarted jenkins using safe restart from ui and as a process too.
But jenkins is failing on some 'ERROR Unable to create file nga/logs/nga.log java.io.IOException'.
We really don't understand where it was trying to write in unix file system.
We tried completely removing that last job of which we had pasted config.xml and restarted it, even same error.
On UI it says : Please wait while Jenkins is getting ready to work…

What resolved this for me with Jenkins 2.150.3 installed was to:
Uninstall ActiveChoices plugin which is the source of the org.biouno.unochoice... in the last line of the log.
Having done that action and restarting Jenkins, the startup log in jenkins.err.log was clean with the last line being Started all plugins.
Yet Jenkins was still stuck on the "Jenkins is starting up" screen.
Uninstall Azure CLI 2.0.59 (at time of writing this is the latest version of Azure CLI).
This fixed it for me. Jenkins login page appeared.
Azure CLI 2.0.59 kills Jenkins 2.150.3!
I suspect unochoice plugin may have nothing to do with it.
I recently upgraded Jenkins from 1.506 to 1.515
After the upgrade, Jenkins doesn't seem to start. The logs are full of warnings like:
WARNING: Failed to load hudson.scm.Cvs...
java.lang.InstantiationException: file:/jenkins/plugins/cvs/WEB-INF/classes/META-INF/annotations/hudson.Extension might need to be rebuilt: java.lang.ClassNotFoundException: hudson.scm.Cvs...
And the web GUI is inaccessible (times out).
I have downgraded to 1.506 again, but same result.
Since all the log warnings are CVS related (which I don't use, we're on svn), I tried deleting
/jenkins/plugins/cvs
/jenkins/plugins/cvs.jpi
But they come back after each restart, along with all the warnings.
I am running jenkins as a war in a dedicated tomcat running on Solaris.
Right now, Jenkins is completely inaccessible. Any pointers appreciated!

WARNING: Failed to scout hudson.scm.cvstagging.LegacyTagAction$LegacyTagActionDescriptor
I resolved this by clearing the "Workspace Root Directory". That is:
Stopping Jenkins
Moving the workspace folder (mv JENKINS_HOME/workspace JENKINS_HOME/workspace-old)
Creating a new workspace (mkdir JENKINS_HOME/workspace)
Restarting Jenkins
I don't what became corrupted, or how, but this solution didn't seem to have any adverse affects.
According to the Jenkins config page (Jenkins > Manage Jenkins > Configure System > Click Advance button near Home directory) the Workspace Root Directory is used to "Specify where Jenkins would store job workspaces on the master node."
From what I could determine, it seems to just store the files checked out from svn for each job, which are obviously easily replaced.
Anyway, all working again now.
And the upgrade worked fine second time around.
