Using the latest released components user can show password details in output using dsl pipeline job. Fragments can be used to construct password from output using unorthodox job method below.

How to reproduce

1. Create credential username pass with id cred_user_id
e.g.
store (Jenkins) --> Domain (DevOps) --> Id cred_user_id
Username: cred_user
Password: userxPass~3&XX?yy%9

2. Create DSL pipeline job per below

Pipeline Code
======================

pipeline

environment

stages
{
stage('Do: Something')
{
steps
{
sh "echo ${MY_CREDENTIAL}"
sh "echo ${MY_CREDENTIAL_USR}:${MY_CREDENTIAL_PSW}"
}
}
}
}

3. Run, output (below) has masked username and unmasked password details showing

[Pipeline] sh
+ 'XX?yy%9'
+ echo ****:userxPass~3
****:userxPass~3
/var/lib/jenkins/jobs/NRP/jobs/9-DevOps-Support/jobs/jenkins_bug/workspace@tmp/durable-865f9359/script.sh: line 1: XX?yy%9: command not found
