Linux – Jenkins behind proxy – illegal character in proxy url

JenkinslinuxPROXY

I'm running Jenkins behind corporate proxy. My proxy password contains special characters something like 'P@ssw0rd'.

Getting below exception while building pipeline

I'm getting a positive response in validating proxy with test URL.

Proxy URL snippet –

http://user:P%40ssw0rd@internet_proxy.abc.com:80

Any "special" character needs to be percent-escaped, particularly @, because that is the separator between the password and hostname portions of a URL.
