Hello,

Here are the steps that make the active parameters groovy script disappear :

• Configure a new Jenkins 2 pipeline project
• Declare active parameters with groovy scripts
• Save
• (build)
• Restart Jenkins with the url : http://myjenkins:8080/restart
• The active parameters are still here, but the textareas containing the groovy scripts are blank

Thanks for your support
If it can help, I have this in jenkins.err.log when I save the job configuration :

The active parameter declaration is the following :

Simple select

if (Type.equals("Build complet")) {
    return [];
} else {
    return ["Etape 1", "Etape 2"]
}
