Use of variables (bash script) in the mail body in jenkins - bash

I currently have the following script:
var = foo
And the configuration of the email (Editable Email Publisher) I have it like this:
configuration Email Publisher
Reading in other questions, someone said that it worked for him using this:
${ENV, var="var"}
However, it does not work for me, can you help me please?

When you run a script that add environment variable the lifetime of this variable is only until the script ends.
You have plugin Environment Injector (was EnvInject Plugin) that using this plugin you can inject variable to all the job life time.
So if you want to add variable in the build section and to use it in the post build section you need to inject the variable.

How can I identify a Buildbot environment by environnment variable?

Does Buildbot provide an environment variable in CI jobs to allow it's identification like e.g. Travis does with TRAVIS?
Last I checked Buildbot does not set an environment variable which has for purpose to indicate that build code is being run through buildbot. In my own setup I do need a few variables that my build code uses so I've setup a dictionary like this:
from buildbot.plugins import util
env = {
'BUILDBOT': '1',
'BUILD_TAG': util.Interpolate("%(prop:buildername)s-%(prop:buildnumber)s"),
'BUILDER': util.Property('buildername')
}
This dictionary can then be used to configure builders:
util.BuilderConfig(
name="foo",
workernames=["a", "b"],
env=env, ...)
The env parameter makes it so that all shell commands issued by this builder will use the environment variables I've declared in my dictionary.
I use BUILDBOT to detect whether the code is running in buildbot at all. The other variables are passed over to services like Sauce Labs and BrowserStack in order to identify the builds there, or they are used for diagnostic purposes.

Environment Variables on Heroku and Mailgun Problems with Phoenix Framework

I was following this guide on deploying to Heroku and this one for sending email.
Everything works fine in development. My variables are set in Heroku:
heroku config
...
MAILGUN_DOMAIN: https://api.mailgun.net/v3/xxxxxx.mailgun.org
MAILGUN_KEY: key-3-xxxxxx
...
And loaded from the config files like so:
config :take_two, Mailer,
domain: System.get_env("MAILGUN_DOMAIN"),
key: System.get_env("MAILGUN_KEY")
However when I try to send email on Heroku when the Mailgun config is set from environment variables I get this error:
** (FunctionClauseError) no function clause matching in IO.chardata_to_string/1
(elixir) lib/io.ex:346: IO.chardata_to_string(nil)
(elixir) lib/path.ex:467: Path.join/2
(elixir) lib/path.ex:449: Path.join/1
lib/client.ex:44: Mailgun.Client.send_without_attachments/2
This happens when the domain is not set for the Mailgun Client. But it is supposed to be set from the environment variable. I made a simple module to test:
defmodule TakeTwo.Mailer do
require Logger
use Mailgun.Client,
Application.get_env(:take_two, Mailer)
def blank_shot do
Logger.info Application.get_env(:take_two, Mailer)[:domain]
Logger.info Application.get_env(:take_two, Mailer)[:key]
send_email from: "steve#xxx.com", to: "speggy#xxx.com", subject: "Hello", text: "This is a blank shot"
end
When I run TakeTwo.Mailer.blank_shot I see the correct domain/key variables logged followed by the error. I am not sure how to debug the Mailgun client remotely.
Finally, if I recreate the above module in the shell (after running heroku run iex -S mix) it works just fine!?
I feel like when the original module is being loaded perhaps the environment variables have yet to be loaded??
The answer was a little buried in a comment so I wanted to make it easier to find. As the other answer mentions, the environment variables aren't available, but the buildpack lets you configure them to be:
I created a elixir_buildpack.config file and added the following:
config_vars_to_export=(DATABASE_URL MAILGUN_DOMAIN MAILGUN_KEY SECRET_KEY_BASE)
The environment variables aren't available at build time. I had the same issue and decided to get rid of the macro carrying the configuration. You can use this patch to move on.

Access to build environment variables from a groovy script in a Jenkins build step (Windows)

I'm using Scriptler plugin, so I can run a groovy script as a build step. My Jenkins slaves are running on windows in service mode. With scriptler, I don't need to use windows batch scripts.
But I have trouble to get the environment variables in a build step... This is working:
System.getenv("BASE")
Where BASE is part of the env-vars on jenkins startup. However, I would like to get
%JOB_NAME%
If I'm adding an "Execute Windows batch command" build step:
echo %JOB_NAME%
It works.
If I'm adding a scriptler script as a build step with the same settings:
println "JOB_NAME: " + System.getenv("JOB_NAME")
I'm getting:
JOB_NAME: null
So how can I reach the injected environment variables from a groovy script as a build step?
build and listener objects are presenting during system groovy execution. You can do this:
def myVar = build.getEnvironment(listener).get('myVar')
You might be able to get them like this:
def thr = Thread.currentThread()
def build = thr?.executable
def envVarsMap = build.parent.builds[0].properties.get("envVars")
On jenkins 2.x, with groovy plugin 2.0, running SystemGroovyScript I managed to get to build variables, as below:
def build = this.getProperty('binding').getVariable('build')
def listener = this.getProperty('binding').getVariable('listener')
def env = build.getEnvironment(listener)
println env.MY_VARIABLE
If you are using goovy from file, simple System.getenv('MY_VARIABLE') is sufficient
The Scriptler Groovy script doesn't seem to get all the environment variables of the build. But what you can do is force them in as parameters to the script:
When you add the Scriptler build step into your job, select the option "Define script parameters"
Add a parameter for each environment variable you want to pass in. For example "Name: JOB_NAME", "Value: $JOB_NAME". The value will get expanded from the Jenkins build environment using '$envName' type variables, most fields in the job configuration settings support this sort of expansion from my experience.
In your script, you should have a variable with the same name as the parameter, so you can access the parameters with something like:
println "JOB_NAME = $JOB_NAME"
I haven't used Sciptler myself apart from some experimentation, but your question posed an interesting problem. I hope this helps!
The only way I could get this to work (on Linux) was to follow this advice:
https://wiki.jenkins-ci.org/display/JENKINS/Parameterized+System+Groovy+script
import hudson.model.*
// get current thread / Executor and current build
def thr = Thread.currentThread()
def build = thr?.executable
// if you want the parameter by name ...
def hardcoded_param = "FOOBAR"
def resolver = build.buildVariableResolver
def hardcoded_param_value = resolver.resolve(hardcoded_param)
println "param ${hardcoded_param} value : ${hardcoded_param_value}"
This is on Jenkins 1.624 running on CentOS 6.7
Jenkins 2.x has the global variables. env is one of them from any script...
println env.JOB_NAME
More at https://build.intuit.com/services-config/pipeline-syntax/globals#env
One thing to note, if you are using a freestyle job, you won't be able to access build parameters or the Jenkins JVM's environment UNLESS you are using System Groovy Script build steps. I spent hours googling and researching before gathering enough clues to figure that out.
In System Groovy Script (Jenkins 2.89), I was able to use the environmental variable to disable another Jenkins job
import jenkins.*
import jenkins.model.*
def env = binding.build.environment
Jenkins.instance.getItemByFullName(env.job_name).setDisabled(false)
I also added a conditional step so as to either enable or disable another Jenkins job.
Thanks #Allan Lewis, your comment was helpful.

How to send an email from Jenkins only in a release?

I was trying to resolve this issue, and searching forums etc. and trying for myself, without success.
We have a jenkins job and there we use the Release Plugin (with a standard configuration)
In the job then we have the "Perform Maven Release" in the left side to generate a version (tag, change poms, etc.) This work perfect.
We want to send an email to the team when the release has been done.
I tried the enviroment variable that the release plugin sets (IS_M2RELEASEBUILD by default) and combine with the email-ext plugin plugin where I can attach a groovy script (advanced=>trigger=>script trigger)
And I tried a lot of scripts to active the email, and none works, my last chance was:
def env = System.getenv()
env['IS_M2RELEASEBUILD'] == 'true'
but when I perform the release we have not the email sent (so this script evaluate the conditional to false or whatever)
Anyone has this setup in his Jenkins?
Thanks a lot!
You need to use "Editable Email Notification" as "Post-build Action" and paste
def env = build.getEnvironment();
String isRelease = env['IS_M2RELEASEBUILD'];
logger.println "IS_M2RELEASEBUILD="+isRelease;
if ( isRelease == null || isRelease.equals('false')) {
logger.println "cancel=true;";
cancel=true;
}
as Pre-send Script, fill in your E-Mail(s) in "Project Recipient List" and add an "Success"-Trigger.
(precondition is you have not changed the default "Release envrionment variable" in "Maven release build")
https://wiki.jenkins-ci.org/display/JENKINS/Email-ext+plugin
This plugin allows you to configure every aspect of email notifications. You can customize when an email is sent, who should receive it, and what the email says.
This is not an answer, just a suggestion (I can't add comments). Have you tried echoing that environment variable in a post-build and pre-build step?
Have you tried having another build run when the release build completes successfully and have that job send the email, perhaps by running a shell script.

How to pass an integration property to a batch file with CruiseControlNet?

In the build log of my project, i can see these properties:
<integrationProperties>
<CCNetProject>Gdet_T</CCNetProject>
...
<LastModificationDate>4/6/2010 1:29:04 PM</LastModificationDate>
<LastChangeNumber>10841</LastChangeNumber>
</integrationProperties>
I want to pass the property CCNetProject and LastChangeNumber to a batch file. it works well with CCNetProject, as it can be used in the batch as an environment variable %CCNetProject%.
But it doesn't work with other properties (those are not starting with the CCnet prefix) as LastChangeNumber or LastModificationDate.
I tried to pass it as argument, but it fails !
<exec>
<executable>$(WorkingFolderBase)\MyBatch.bat</executable>
<baseDirectory>$(WorkingFolderBase)\</baseDirectory>
<buildArgs>$(LastModificationDate)</buildArgs>
</exec>
I tried to pass it as environment variable, but it fails:
<exec>
<executable>$(WorkingFolderBase)\MyBatch.bat</executable>
<baseDirectory>$(WorkingFolderBase)\</baseDirectory>
<environment>
<variable>
<name>svn_label</name>
<value>"${LastModificationDate}"</value>
</variable>
</environment>
</exec>
The results is always the same when I display the parameter or variable : empty string or the variable name $(svn_label)
I'm sure it is simple, but ... I can't find ! Any idea ?
CCNET passes the following parameters to external programs:
CCNetArtifactDirectory
CCNetBuildCondition
CCNetBuildDate
CCNetBuildTime
CCNetFailureUsers
CCNetIntegrationStatus
CCNetLabel
CCNetLastIntegrationStatus
CCNetListenerFile
CCNetModifyingUsers
CCNetNumericLabel
CCNetProject
CCNetProjectUrl
CCNetRequestSource
CCNetUser
CCNetWorkingDirectory
As you can see LastIntegrationStatus e.g. is available through CCNetLastIntegrationStatus but LastModificationDate e.g. has no equivalent.
You can pass additional arguments via <buildArgs> or <environment> but inside CCNET configuration you have no access on the integration properties mentioned above. Most people starting with CCNET (including myself) try something like <buildArgs>$(CCNetProject)</buildArgs> and fail.
Have a look on my answer to a similar question.
Sorry I can't provide a better solution.
Update (regarding Thinker's suggestion):
Using $[$CCNetLabel] inside CCNET configuration does not seem to work.
Frankly spoken, I would have been rather surprised, if it had. The configuration is something static whereas CCNetLabel is something dynamic, that potentially changes with every integration build. Assuming you have access to these dynamic properties inside the configuration, the configuration might change with every build. Since changing the configuration means restarting the CCNET server automatically, you would cause a server restart with every build. Not actually a desirable behavior, is it?
ok, found the solution.
Need to use a specific label called SvnRevisionLabeller to retrieve the svn revision.
it is then available via the CCNetLabel environement variable.
