Jenkins / JENKINS-62165 Space character at end of parameter name prevents dereferencing this parameter Issue Type: Bug Assignee: Unassigned Components: core Created: 2020-05-05 15:03 Environment: Jenkins LTS 2.222.3 Linux CentOS 7 Priority: Major Reporter: Firmware Tools SE When a space character is present at end of a parameter name, dereferencing this parameter name (without space) will display the string attemting the dereference (i.e. ${name}) instead of the value of this parameter.   Example of this problem: Create a job with a string parameter (e.g. "top_parameter"), but add a space at the end of the name like "top_parameter ", with a default value of anything (e.g. 42) use the parameter value, for example in a build step "Inject Environment variables" like : top_value=${top_parameter} use "top_value" environment variable (e.g. in a shell) ; its value will be the string "${top_parameter}" not 42 Add Comment

Okay, it seems I was misunderstood. Adding a space after the parameter name on purpose was just for the sake of the example. I spent quite some time figuring out some user had indeed mistakenly added a space behind a parameter name (probably a wrong copy/paste) in a weekly multijob (leading to failure of some parts of it). So my request is: could it be possible to add some control on whether a parameter name has trailing (or even leading) "invisible" characters (maybe a warning or an automatic trimming (who, in his right mind, would want a trailing space in a parameter name?)).

Re: Space character at end of parameter name prevents dereferencing this parameter Good point. While there are environments in which this can be desirable, they're rather unusual. So a form validation warning that points out unusual parameter names (also e.g. including a period in the name) that may not work well for some use cases, would be helpful.
