There is no trim feature provided by jenkins for multiline string as we have for single line string parameter.

Multiline text parameter displays as single line

Thus the user may enter details having leading, trailing whitespaces or simply blank lines in the multiline parameter like below. I used ansible to convert the list of files provided in the multiline parameter as a comma seperated string.

I tried converting the jenkins variable inside a Jenkins execute shell script before passing it to ansible but that did not help as well. The solution to the issue is to use trim. It will get rid of leading and trailing spaces. Learn more. Unable to format string passed as multiline jenkins parameter to Ansible Ask Question. Asked 2 months ago.

Off hand, you could convert the multi-line string parameter into an array, remove all of the empty elements, and then convert it back into a string with adelimiter. This would be slightly messy though, and it only handles the whitespace and newline issues. If the users put other bad characters into the input, then those would need to be handled too.

Trim helped resolve the issue. Active Oldest Votes. I'll put this here so the answer is clear then. Sign up or log in Sign up using Google. Sign up using Facebook.

There are different parameter types available, and it is extensible, too. The way parameters take effect is also different depending on the parameter type you choose. String parameters are exposed as environment variables of the same name. Therefore, a builder, like Ant and Shell, can use the parameters. Continuing the above example, the following is a simple example:. Run build and observe output toward the bottom of the log some vars removed for security and brevity :.

Ant works equally well. In the Properties section of the Ant builder, define a build property like:. Note that because of the case sensitivity difference of environment variables in Windows and Unix, all the environment variables added by parameters are in upper case.

File parameter allows a build to accept a file, to be submitted by the user when scheduling a new build. A plugin can define custom parameter types. See ParameterDefinition for the starting point.

When passing parameters through the URL, casing is important! I tried it, but it didn't work. Windows Users : use my. It seems that if a parameter is in a downstream job, the parameter is not set. It would be useful to pass parameters to downstream jobs, if they share the same named parameters. I need to build each svn branches, and there's no easy way to build downstream the branched modules. A question related to the one by Cees Bos: is it possible to specify build parameters when using the "build periodically" feature?

I believe that it would be very useful if the Build Parameters would also work for multi-configuration projects. It would be great to be able to add not only parameter name and value but also specify some description as well, so when user click on ''Build Now" button the parameterized page would give more helpful info about required parameters. Is there a way where I can pass multiple default values to a single parameter and then select the value of the parameter from a dropdown which has the default valuesand then run the build?

It would be nice to have access to the parameters for use in the project configuration as well. How can these parameters be accessed from groovy? Is it possible to make these parameter values available in all fields outside of the build step?After my first experiment in building and publishing our Nuget packages using Jenkins, I wasn't actually anticipating writing a follow up post. As it transpires however, I was unhappy with the level of duplication - at the moment I have 19 packages for our internal libraries, and there are around 70 other non-product libraries that could be turned into packages.

As I did mention originally, Jenkins does recommend that the build script is placed into source control, so I started looking at doing that. I wanted to have a single version that was capable of handling different configurations that some projects have and that would receive any required parameters directly from the Jenkins job.

Fortunately this is both possible and easy to do as you can add custom properties to a Jenkins job which the Groovy scripts can then access. This article will detail how I took my original script, and adapted it to handle 19 and counting! Parameters are switched off and hidden by default, but it's easy enough to enable them.

In the General properties for your job, find and tick the option marked This project is parameterised.

This will then show a button marked Add Parameter which, when clicked, will show a drop-down of the different parameter types available. For my script, I'm going to use single line string, multi-line string and boolean parameters. The parameter name is used as environment variables in batch jobs, therefore you should try and avoid common parameter names such as PATH and also ensure that the name doesn't include special characters such as spaces.

By the time I'd added 19 pipeline projects including converting the four I'd created earlier into parameterised builds running from the same source script, I'd ended up with the following parameters. More parameters than I really wanted, but it covers the different scenarios I need.

Note that with the exception of LIBNAMEall other parameters are optional and the build should still run even if they aren't actually defined. Of the three types above, the first two return null if you request a parameter which doesn't exist - very helpful for when you decide to add a new parameter later and don't want to update all the existing projects!

The third however, will crash the build. It'll be easy to diagnose if this happens as the output log for the build will contain lines similar to the following. So my advice is to only use the interpolation versions when you can guarantee the parameters will exist. In my first attempt at creating the pipeline job, I had a block of variables defined at the top of the script so I could easily edit them when creating the next pipeline.

I'm now going to adapt that block to use parameters. I'm using params to access the parameters to avoid any interpolation crashes. As it's possible the path parameters could be missing or empty, I'm also using a combinePath helper function.

This is a very naive implementation and should probably be made a little more robust. Although Java has a File object which we could use, it is blocked by default as Jenkins runs scripts in a sandbox. As I don't think turning off security features is particularly beneficial, this simple implementation will serve the requirements of my build jobs easily enough.

The multi-line string parameter is exactly the same as a normal string parameter, the difference simply seems to be the type of editor they use. So if you want to treat them as an array of values, you will need to build this yourself using the split function.

Some of my projects are slightly naughty and pull code files from outside their respective library folders.The creation of a parameterized Jenkins build is one of the easiest ways to add flexibility and customization to your continuous integration pipelines. The option to create a parameterized Jenkins build job is a core feature of the popular CI toolso you don't need to install any plug-ins to create one. In the second part of this tutorial, we will extend the parameterized Jenkins build job example and use the Jenkins Git integration plug-in to pull from GitHub.

This isn't a requirement of the first part of this tutorial, though. In step one of this parameterized Jenkins build job example, create a new freestyle projectand name it parameterized-build example. Once you've created the build job, Jenkins will display the item's configuration page.

On this configuration page, there is an unselected checkbox next to text that states: "This project is parameterized. Click the Add Parameter drop-down list a second time, and choose to create a String parameter. The next step in this parameterized Jenkins build example is to add a build step that simply echoes these values back to the console.

To do so, scroll down toward the bottom of the parameterized-build-job configuration page, click the Add build step drop-down box, and choose the Execute Windows batch command option.

In the text input area that appears, just above the link to the Jenkins environment variables listenter the following text:. Save the build joband choose the option to Build with Parameters. Accept the defaults, and click the Build button. The default values should be echoed in the console output. Change the default values, and run the parameterized Jenkins build example once again.

Notice how the updated values are echoed in the console output. The first portion of this Jenkins parameterized build example had no prerequisites other than a working Jenkins installation. The remainder of this Jenkins tutorial requires the Git plug-in and the JDK's bin directory on the computer's system path.

In another Jenkins Git integration tutorialwe pulled a Java project from GitHub and generated Javadoc for all of the source files with the following command:. We will now expand upon this script and incorporate Jenkins build parameters. This will provide the program with a choice to generate Javadoc or not and, if generated, where it'll be located. Once the Git repository is configured, move back to the build script, and update it with the following code:.

Save the build, and run the parameterized Jenkins build example again by clicking on the Build Job with Parameters option.So this isn't a Pipeline-specific problem - the same thing happens with Parameterized Trigger calling a downstream freestyle build. Core doesn't seem to know what to do with a multiline string parameter that isn't submitted through the UI - the actual parameter that is available at runtime is fine, but the saved parameter info on the run is wrong.

If anyone has a reference of where I should start looking into the root cause of this, I would appreciate it. Issues Reports Components Test sessions.

A parameter using one of these types will pop up and prompt the user for input when they run the Jenkins job. The available parameter types for Jenkins pipeline are: According to here.

There is no multiline string input parameter listed for pipeline. The Jenkins documentation say the documentation is "young" and still incomplete. Multi-line string parameters are in the out-of-the-box Jenkins package, but doesn't seem to be there in the pipeline. This pops up a multi-line text input prompt which becomes the parameter value which you can refer to later as params. This is not documented in the Jenkins Pipeline documentation, so there might be issues like it being unsupported or withdrawn in a future release.

Or it could go the other way and they might document it in the next release. On the plugin select whatever you want for the plugin. Learn more. Asked 1 year, 9 months ago. Active 1 year, 1 month ago.
