Jenkins Credentials Store Access via Groovy

Question

I have found a way to access the credentials store in Jenkins:

def getPassword = { username ->     def creds = com.cloudbees.plugins.credentials.CredentialsProvider.lookupCredentials(         com.cloudbees.plugins.credentials.common.StandardUsernamePasswordCredentials.class,         jenkins.model.Jenkins.instance     )      def c = creds.findResult { it.username == username ? it : null }      if ( c ) {         println "found credential ${c.id} for username ${c.username}"          def credentials_store = jenkins.model.Jenkins.instance.getExtensionList(             'com.cloudbees.plugins.credentials.SystemCredentialsProvider'             )[0].getStore()           println "result: " + credentials_store     } else {       println "could not find credential for ${username}"     } }  getPassword("XYZ") 

But now i would like to get the password for the appropriate user which i can't do...

I always get unknown method etc. if i try to access passord etc.

The reason for doing this is to use this user/password to call git and extract information from repository..

I always get something like this:

result: com.cloudbees.plugins.credentials.SystemCredentialsProvider$StoreImpl@1639eab2 

Update

After experimenting more (and the hint of Jeanne Boyarsky) with it i found that i was thinking to compilcated. The following already gives me the password for the user:

def getUserPassword = { username ->     def creds = com.cloudbees.plugins.credentials.CredentialsProvider.lookupCredentials(             com.cloudbees.plugins.credentials.common.StandardUsernamePasswordCredentials.class,             jenkins.model.Jenkins.instance             )      def c = creds.findResult { it.username == username ? it : null }      if ( c ) {         return c.password     } else {         println "could not find credential for ${username}"     } } 

Furthermore by using the following snippet you can iterate over the whole credentials store:

def credentials_store = jenkins.model.Jenkins.instance.getExtensionList(         'com.cloudbees.plugins.credentials.SystemCredentialsProvider'         )  println "credentials_store: ${credentials_store}" println " Description: ${credentials_store.description}" println " Target: ${credentials_store.target}" credentials_store.each {  println "credentials_store.each: ${it}" }  credentials_store[0].credentials.each { it ->     println "credentials: -> ${it}"     if (it instanceof com.cloudbees.plugins.credentials.impl.UsernamePasswordCredentialsImpl) {         println "XXX: username: ${it.username} password: ${it.password} description: ${it.description}"     } } 

And you will get an output like this:

[(master)]: credentials_store: [com.cloudbees.plugins.credentials.SystemCredentialsProvider@5a2822be]  Description: [The descriptions...]  Target: [com.cloudbees.plugins.credentials.SystemCredentialsProvider@5a2822be] credentials_store.each: com.cloudbees.plugins.credentials.SystemCredentialsProvider@5a2822be credentials: -> com.cloudbees.jenkins.plugins.sshcredentials.impl.BasicSSHUserPrivateKey@38357ca1 credentials: -> com.cloudbees.jenkins.plugins.sshcredentials.impl.BasicSSHUserPrivateKey@47cf7703 credentials: -> com.cloudbees.plugins.credentials.impl.UsernamePasswordCredentialsImpl@739abac5 XXX: username: User1 password: Password description: The description of the user. credentials: -> com.cloudbees.plugins.credentials.impl.UsernamePasswordCredentialsImpl@884a53e6 XXX: username: User2 password: Password1 description: The description of the user1. Result:   [com.cloudbees.jenkins.plugins.sshcredentials.impl.BasicSSHUserPrivateKey@38357ca1, com.cloudbees.jenkins.plugins.sshcredentials.impl.BasicSSHUserPrivateKey@47cf7703, com.cloudbees.plugins.credentials.impl.UsernamePasswordCredentialsImpl@739abac5, com.cloudbees.plugins.credentials.impl.UsernamePasswordCredentialsImpl@884a53e6] 

So by using the appropriate class in the instanceof clause you can select what you need.

This works. It gets the credentials rather than the store.

I didn't write any error handling so it blows up if you don't have a credentials object set up (or probably if you have two). That part is easy to add though. The tricky part is getting the right APIs!

def getPassword = { username ->     def creds = com.cloudbees.plugins.credentials.CredentialsProvider.lookupCredentials(         com.cloudbees.plugins.credentials.common.StandardUsernamePasswordCredentials.class,         jenkins.model.Jenkins.instance     )      def c = creds.findResult { it.username == username ? it : null }      if ( c ) {         println "found credential ${c.id} for username ${c.username}"          def systemCredentialsProvider = jenkins.model.Jenkins.instance.getExtensionList(             'com.cloudbees.plugins.credentials.SystemCredentialsProvider'             ).first()        def password = systemCredentialsProvider.credentials.first().password        println password       } else {       println "could not find credential for ${username}"     } }  getPassword("jeanne")

The official solution n the jenkins wiki

Printing a list of all the credentials in the system and their IDs.

def creds = com.cloudbees.plugins.credentials.CredentialsProvider.lookupCredentials(         com.cloudbees.plugins.credentials.Credentials.class,         Jenkins.instance,         null,         null ); for (c in creds) {     println(c.id + ": " + c.description) }
