How to use hudson.util.Secret in the project?

[darewreck54]

I'm injecting passwords from my dsl job into the created job. However, I want to encrypt them with import hudson.util.Secret; but i'm having the hardest time including the library without breaking the test. The groovy script works when executed in jenkins but depending on what version of the import hudson.util.Secret; i use i'll get a range of errors.

I was wondering how do you go about using the library or if there is another way to encrypt the passwords injected into the job so they aren't visible from the /config.xml file

When I try to use the latest

  compile 'org.eclipse.hudson:hudson-core:3.3.3'

to my gradle project with

repositories {
    mavenCentral()
    maven { url 'https://repo.jenkins-ci.org/releases/' }
    jcenter()
}

I get the following error:

* What went wrong:

I've tried several other version as well, and in those cases I would get run time issue at the point when it's actually the secret.encrypt is actually being executed.

 injectGlobalPasswords(false)
                maskPasswordParameters(true)
                passwordEntries() {
                    for (password in passwords.entrySet()) {
                        Secret secret = Secret.fromString(password.getValue())
                        'EnvInjectPasswordEntry' {
                            name(password.getKey())
                            value(secret.getEncryptedValue())
                        }
                    }

                }

I'm trying to execute something like above which results in the issue.

Any advice appreciated
thanks
