Jenkins AbstractTrigger checkIfModified method called multiple times

[Shashank Bhargav]

Hi,

We have a requirement where poll has to be done to DB, check some 
conditions and based on conditions satisfied trigger a build. So we have 
extended "AbstractTrigger" class and overriden "checkIfModified" method.
But what is noticed is the method is being called multiple times within a 
minute even though the cron expression is set to poll every minute. Its not 
very consistent on how many times a minute, has anyone faced this before? 
Could someone help.

Is there an example of how to do caching of some folders with

You can use the warnings plugin to show compiler warnings. There is an parser

On the “Known Hosts Key Validation" agents, where you imported the key on the

The other error seems related with the format of the host public key, it

kubernets plugin jnlp4

[Edward Bond]

Hello All,

I am using Jenkins LTS, 2.107.2. with kubernetes plugin: 1.1.3, jnlp-2, 
using kops inside aws. 

I have to have jnlp2-connect enabled because using jnlp4 has a higher 
failure rate.

Currently I am getting abount a 80% success rate with my current setup. 
When I upgraded ( 2 months ago ) to latest master and latest k8s plugin I 
was having about a 15% success rate of builds.

Anyone have a list of versions that work for them and jnlp4?

It would be awesome to have a known good config of:

   1. Master docker image version
   2. K8s plugin version
   3. jnlp pod agent base image version


Thanks in advance.

Job corrupt when using enable button

[Mark Smit]

Hello all,

We are moving jobs from one Jenkins machine to another. On the old machine 
we disable the job, then we copy the project in the jobs folder from the 
old to the new machine. In the new Jenkins I load the jobs by reloading the 
configuration. All copied jobs appear to the existing ones, but they are 
still disabled. I open each job and press the Enable button in the status 
view. And then my problem appears: the job is enabled, but builds nothing. 
When I compare the latest with the previous configuration I see that a huge 
block is added to the configuration with the dependency graph information. 
Why does Jenkins add this? Such corrupt config.xml files are more than 200k 
in size, were they are normally around 10k.
I already did find a work around: to enable a job I open the configuration, 
remove the check from 'disable project' and save the configuration. After 
that the configuration does not get corrupt. Has anyone experienced the 
same issue? And perhaps has a solution?
Jenkins version: 2.107.2

regards,
Mark

From upstream pipeline, how to know on which node has been executed downstream pipeline in parallel job execution

[Vincent SCHMITT]

Hello

I have an upstream scripted pipeline calling in parallel downstream script 
pipeline.
I would like after the run, that the upstream pipeline know on which slave 
they have been executed.

Would you know how can we do this?


Upstream pipeline ("pipeline 123"):
import hudson.Util;

node ("master") {
cleanWs()
def tc_job_name
def tc=["tc002","tc003"]
def branches=[:]   

stage ("phase")   {
tc_job_name = "subpipeline"

for (int i = 0; i <= tc.size()-1; i++) {
def index = i //if we tried to use i below, it would equal 
tc.size()-1 in each job execution.
branches["${tc[index]}"] = {
def first_run,job_hudson,build_hudson,build_env
first_run = build job: tc_job_name, parameters: 
[string(name:'dummy', value: "${index}")], description:'${tc[index]}', 
propagate: false

def rawbuild = first_run.getRawBuild() 
def build_properties = rawbuild.getProperties()
def log = build_properties['log']

def node = log.tokenize('\n').findAll {it.contains 
'Running on'}.each {it}[0].split(" ")[2]
echo node

   } // end of branches["${tc[index]}"] definition
} // for (int i = 0; i <= tc.size()-1; i++) 
parallel branches
} // stage phase
} // node ("master") 


Downstream pipeline ("subpipeline"):
node('only_tc') {
stage ("test") {
echo env.NODE_NAME
}
}

What has been tried:
* In upstream pipeline I have tried to get the owner of the executor 
launching the downstream pipeline:

tc_job_name ='subpipeline'

first_run=build job: job_name

def build_hudson = first_run.getRawBuild()

def build_properties = build_hudson.getProperties() 

def executor = build_properties['executor']

println "Node: "+ executor.getOwner().getCaption()


But it doesn't work with parallelized job execution , it outputs "Master" 
which is not the jenkins slave executor


* Getting NODE_NAME environment parameter:

tc_job_name ='subpipeline'

first_run=build job: job_name

def build_hudson = first_run.getRawBuild()

 def build_env = build_hudson.getEnvironment()

   println build_env.get("NODE_NAME","no node name")


But the environment variables of a pipeline is not the same as a freestyle 
job and it has not any NODE_NAME


* Parsing the log environment variable: (see first sample), but it's not 
the right way to do I guess.


Thanks in advanced !!

RE: Best Practices Jenkins in a Microsoft environment

[John.Peterson]

We use Jenkins in a windows environment for system tests.  We are still using 
Cruise Control for build control, but are eventually planning to migrate to 
Jenkins so it is all self contained and build jobs can chain (or integrate) 
system test jobs.

It’s pretty straight forward.  We just installed Jenkins and created some 
projects.

We are using 2 methods of launching a test.  “Monitor Changes in Directory” and 
a direct launch from CC such as https://OurJenkins:8080/jobs/ThisTestJob:Delay=0

The biggest non-default thing we have done is to do a groovy post-build which 
renames the job sequence number to = the build number which is much more useful.

We are using vSphere plugin to launch VM’s as needed and control snapshots.

Subject: Best Practices Jenkins in a Microsoft environment

Hello All,

I am new to Jenkins and was hoping someone can direct me to any information 
with regard to 'Best Practices" using Jenkins in a Microsoft shop.
Or some feedback from some who has a similar environment with regard to using 
Jenkins.

Some background on tools etc..:
Visual Studio 2017
C#
ASP.net Websites wish to convert to Web Applications
SVN (Subversion)
MSBuild currently powershell command line builds to build releases

Currently the build/deploy process is very manual
Basically an operator pulls the projects from SVN and performs cleanup, revert 
etc...
using MSBuild; complies the appropriate projects, compresses the output and 
manually deploys the builds to the respective environment (leaving out a lot of 
details)
Btw, we are planning on convert ASP websites to ASP Web Applications so as to 
utilize transforms etc..

With CI in mind, We are planning on using Jenkins->Web deploy in the future  to 
perform releases into the Test, QA, Production etc... environments
Of course this is a very cursory explanation, however I was primarily curious 
of any lessons learned when setting up Jenkins in this scenario?
Hopefully even some examples of a pipeline or Job stream which could suffice as 
a general template. It would interesting for instance if Jenkins is interacting 
with Web Deploy.

Any help would be sincerely appreciated.

Thank you!!!

How to inject an env variable from declarative script?

[David Aldrich]

Hi

I'm trying to fix the occasional MSBuild error:

"Fatal error C1090: PDB API call failed, error code '23'"

1.  The advice given in 
JENKINS-9104 is to inject 
the following environment variable using EnvInject:

_MSPDBSRV_ENDPOINT_=$BUILD_TAG

I don't really understand the difference between defining and injecting an 
environment variable.  I want to specify this setting directly in a declarative 
script.  I could do:

stage('build_VisualStudio') {
agent { label "jenkinswin10" }
environment { _MSPDBSRV_ENDPOINT_=$BUILD_TAG }
etc.

Would that be sufficient or must env variable injection be done in a different 
way?

Best regards

David

Re: automating jenkins (master) setup - plugins / extensions and their configs

[nicolas de loof]

init.groovy scripts is a very powerful way to setup jenkins but require to
know jenkins / plugins programmatic API. If you're not a plugin developer
this might be very uncomfortable to write and maintain.

As an alternative, you might be interested in

automating jenkins (master) setup - plugins / extensions and their configs

[Alex Els]

Hi there,

I'm trying to create a automated setup of Jenkins masters and am struggling 
with setting up custom plugins, like terraform or docker, programatically 
via groovy scripts in  
init.groovy.d

 are there any good resources on how to do this?

I'm using the Jenkins docker image, which can automatically install all the 
desired plugins, but it's a mystery on how to use groovy init scripts to 
configure any custom installed plugin/extension. I've found resources that 
configure things like maven etc., but nothing that would help me set up a 
"installation" of `terraform` and such .. 

How do people on here go about this in general? Just do the clicky thing 
and the put the XML files into Git (minus the passwords, if any, of 
course)? I'd really rather not do that, and use the groovy init scripts 
instead, if at all possible for these cases?

Thanks
Alex

Problem running Visual Studio 2017 build tools from Jenkins

[David Aldrich]

Hi

I'm having difficulty running the Visual Studio 2017 build tools on a Windows 
10 slave as a Jenkins job.  I have described my problem in StackOverflow:

https://stackoverflow.com/questions/49922959/how-to-fix-java-was-unexpected-at-this-time-when-invoking-vs-2017-build-to/49944377#49944377

If anyone has this working or can advise on the problem I would be grateful.

Best regards

David

Re: setNextBuildNumber from upstream job

[Victor Martinez]

IIUC, there are two different points here:

*1) Variable interpolation.*

It looks like *$COPY_FROM_BUILD* is not interpolated unless it's double 
quoted: 


nextBuildNumber("$COPY_FROM_BUILD") 

*NOTE*: that particular variable might be declared somehow, see below


*2) Upstream parameter.*

Off the top of my head: 

It might depends on how the upstream job triggers the downstream job.


a) If it's using the build step then you might create a new parameter to be 
used only when the upstream pipeline triggered the downstream job which 
will use the parameters accordingly.
b) Using the feature property *'*
*hudson.model.ParametersAction.keepUndefinedParameters'* . (described: 
https://wiki.jenkins.io/display/JENKINS/Features+controlled+by+system+properties)
 
then you won't need to declare the parameter in the downstream job. 
Although, it  might be unsafe as explained
c) Other way, it might be using the archive and copyArtifact 

 
step and then readFile step 

d) I'm pretty sure there are other ways that someone else could help with. 
:)


Cheers
