I'm trying to send an email with body text given in a string variable, and fail.
The line of code I use is:
mailtxt = 'ABCD'
emailext attachLog: false, subject:'$DEFAULT_SUBJECT' , to:'mymail#gmail.com' , replyTo:'$DEFAULT_REPLYTO', body: '''$mailtxt<div>'''
I have tried several combinations of code fences and $, but never get the string value.
Any suggestions?
Thanks!
The string variable can be addressed by "${string}".
I suggest for you to read the official Groovy language documentation.

Is it possible to give multiple values as input in a string parameter in the Jenkins job..?
If yes, what will be the syntax and how are we calling that in a for loop so the values take one after the other.?
This is for a declarative job in Jenkins.
Thank you for the help in advance
parameters {
string(name: "usernames", value: list.join (","), description: "enter the user names")
}
stages{
need the syntax for this --> //for user in usernames list
do
$echo ---> username
this username which print will be called in my curl command one after the other.
so please do help me with the right path
Generally it is only possible to pass one string.
That being said, since you are using strings you can encode whatever data you want in them.
Suppose you want to pass the pipeline a list of strings myList with values ['foo', 'bar', 'baz']. In the calling job you could simply do:
build ... parameters(string(name: "myString", value: myList.join(",")))
which passes 'foo, bar, baz' to the called job. There you could parse it out again:
params.myString.split(',') // results in ['foo', 'bar', 'baz']
To iterate over this, you could use a for-in loop or a list function like each or collect.
In order to iterate over all the elements you receive you can use the each method
stages {
stage("Iterate over parameters"){
script{
def userNames = params.userNamesString.split(',')
userNames.each { user ->
echo "$user"
}
}
}
}
Alternativly (instead of the userNames.each block you can just use a for-in statement:
for(userName in userNames){
echo "$userName"
}
For more informations on this please have a look at the links I included in my previous answer.
function Main(Inhalt)
print(string.len(Inhalt))
end
Main(Bla)
This is just a example, I run in multiple problems like: "input:3: bad argument #1 to 'len' (string expected, got nil)" (Like here), or anything else with unexpected.
I'm kinda new to this, so please explain it to me from ground up I'm trying to figure out for a pretty long time. I already tried to convert this to a string with tostring(), but yes I'm missing something. Thanks for your help.
In this case Bla either needs to be a string which you can fix by putting quotes around it
function Main(Inhalt)
print(string.len(Inhalt))
end
Main("Bla")
or needs to be a variable that contains a string
Bla="test string"
function Main(Inhalt)
print(string.len(Inhalt))
end
Main(Bla)
Not a lua expert but it seems like you're trying to get the length of the string value Bla. The way you've written it right now does not indicate Bla is of string type. If you change it to the following, this should work.
function Main(Inhalt)
print(string.len(Inhalt))
end
Main("Bla")
Try this:
string1 = "Bla"
Main(string1)
In your code snippet Bla is not defined. Strings are surrounded by "".
I'm trying to use groovy to update Jenkins job config.xml by the following code
def updateParameter(String key, String value){
println "changing defult value as $value for key $key"
def xml = new XmlSlurper().parseText(jobConfig)
xml.properties.'hudson.model.ParametersDefinitionProperty'.'parameterDefinitions'.'hudson.model.StringParameterDefinition'.each {
println 'found parameter: ' + it.name
if(it.name.text() == key){
println('default value changed')
it.defaultValue=value
}
}
jobConfig = XmlUtil.serialize(xml)
}
When running jobConfig = XmlUtil.serialize(xml), it changes the format, which is pretty, but I lost link break in pipeline plugin, so pipeline script doesn't work anymore. Is there a way to convert GPathResult to String without format changing?
Best Regards,
Eric
It is all my fault, the line breaks were removed when I read the xml. It seems XmlUtil.serialize(xml) doen't format the text of a xml tag, which is good :)

In my Jenkins step I have windows batch command which runs a java jar file (java -Dfile.encoding=UTF-8 -jar C:\Test1\Test.jar C:\Test\test.log) and output of which is a String value (verified Jenkins console the string is getting printed) . How will I use this string content and insert in the editable email content body so I can send this content as an email . I wouldn't want the whole Jenkins console in the email only this String. I would assume the string has to be set as an environment variable after the script runs . Not sure how exactly I can use EnvInjPlugin for my scenario if at all it can be.
Try to use pre-send script.
For example You have in log the string like: "this random integer should be in email content: 3432805"
and want to add randomly generated integer to email content.
Set the Default Content with whatever you want but add some
value which will be replaced. For example:
This is the random int from build.log: TO_REPLACE
Then click "Advanced Settings" and add Pre-send Script:
String addThisStringToContent = "";
build.getLog(1000).each() { line ->
java.util.regex.Pattern p = java.util.regex.Pattern.compile("random\\sinteger.+\\:\\s(\\d+)");
java.util.regex.Matcher m = p.matcher(line);
if (m.find()) {
addThisStringToContent = m.group(1);
}
}
if (addThisStringToContent == "") {
logger.println("Proper string not found. Email content has not been updated.");
} else {
String contentToSet = ((javax.mail.Multipart)msg.getContent()).getBodyPart(0).getContent().toString().replace("TO_REPLACE", addThisStringToContent);
msg.setContent(contentToSet, "text/plain");
}
where:
build.getLog(1000) - retrieves the last 1000 lines of build output.
Pattern.compile("random\\sinteger.+\\:\\s(\\d+)") - regex to find the proper string
"text/plain" - Content Type
String contentToSet = ((javax.mail.Multipart)msg.getContent()).getBodyPart(0).getContent().toString().replace("TO_REPLACE", addThisStringToContent); - replaces the string TO_REPLACE with your value
Hope it will help you.
Unfortunately I have not enough reputation to comment Alex' great answer, so I write a new answer. The call
msg.setContent(contentToSet, "text/plain")
has two disadvantages:
Special characters are garbled
An attachment gets lost
So I use the following call to set the modified text
((javax.mail.Multipart)msg.getContent()).getBodyPart(0).setContent(contentToSet, "text/plain;charset=UTF-8")
I'm developing an app using Grails. I want to get length of array.
I got a wrong value. Here is my code,
def Medias = params.medias
println params.medias // I got [37, 40]
println params.medias.size() // I got 7 but it should be 2
What I did wrong ?
Thanks for help.
What is params.medias (where is it being set)?
If Grials is treating it as a string, then using size() will return the length of the string, rather than an array.
Does:
println params.medias.length
also return 7?
You can check what Grails thinks an object is by using the assert keyword.
If it is indeed a string, you can try the following code to convert it into an array:
def mediasArray = Eval.me(params.medias)
println mediasArray.size()
The downside of this is that Eval presents the possibility of unwanted code execution if the params.medias is provided by an end user, or can be maliciously modified outside of your compiled code.
A good snippet on the "evil (or lack thereof) of eval" is here if you're interested (not mine):
https://javascriptweblog.wordpress.com/2010/04/19/how-evil-is-eval/
I think 7 is result of length of the string : "[37,40]"
Seems your media variable is an array not a collection
Try : params.medias.length
Thanks to everyone. I've found my mistake
First of all, I sent an array from client and my params.medias returned null,so I converted it to string but it is a wrong way.
Finally, I sent and array from client as array and in the grails, I got a params by
params."medias[]"
List medias = params.list('medias')
