Jenkins Pipeline - getting java.io.NotSerializableException with sh and curl

Question

I'm creating a jenkins pipeline which creates a Jira Ticket at some point. Unfortunately I'm getting: java.io.NotSerializableException: org.codehaus.groovy.runtime.EncodingGroovyMethods$1

Code:

    token = createEncodedToken()

    def curlCommand = "curl -H 'Authorization: Basic ${token}' -X POST -d \'${payload}\' -H 'Content-Type: application/json' ${jira_url} > JIRA_TICKET"

    try {
        println "executing: ${curlCommand}"
        sh "${curlCommand}"
    } catch (NotSerializableException err) {
        println "${err}"
    }

createEncodedToken:

def createEncodedToken() {
   def auth = "${jira_user}:${jira_password}"
   return auth.bytes.encodeBase64()
}

The resulting curlCommand works! I can send it in curl or in a sample pipeline. But as soon as I use it in my jira.groovy script I get the exception.

[Pipeline] echo
executing: curl -H "Authorization: Basic MYTOKEN=" -X POST -d "{"fields":{"project":{"key":"KEY"},"summary":"Pipeline Test","description":"Creating of an issue using project keys and issue type names using the REST API","issuetype":{"name":"Story"}}}" -H "Content-Type: application/json" https://MYJIRA/rest/api/2/issue/ > JIRA_TICKET
[Pipeline] sh
[plinetest] Running shell script
[Pipeline] echo
java.io.NotSerializableException: org.codehaus.groovy.runtime.EncodingGroovyMethods$1

The output file JIRA_TICKET is used to read the resulting issue-key.

Fun fact: although I get an exception, the ticket is created... but I can't read the JIRA_TICKET file.

I'm currently testing it in a Sandbox Pipeline:

def jira = fileLoader.fromGit('jira.groovy', 'MYBITBUCKET-pipeline.git', 'master', 'CREDS', '')
echo "create ticket"
def payload = '{"fields":{"project":{"key":"KEY"},"summary":"Pipeline  Test","description":"Creating of an issue using project keys and issue type names using the REST API","issuetype":{"name":"Story"}}}'
jira.createTicket(payload)

The call is tested and works fine. Maybe the jira lib causes the problem? I'm aware of the Serializable concept of jenkins pipeline, but I don't get what I miss. I'm pretty clueless right now... Any help is appreciated.

It doesn't :( I moved the curl execution to a separate method and annotated it with @NonCPS. Still the same error. — Johannes Zink, Sep 02 '16 at 16:19
What is the code inside `createEncodedToken()`? I bet it causes the issue. — izzekil, Sep 03 '16 at 20:19

encodeBase64() does not return a string. It returns a class which implements groovy.lang.Writeable, which has a toString() method.

You need to call toString() explicitly.

Please try to use new URL(jira_url).openConnection(); instead of curl. You can refer to this Groovy built-in REST/HTTP client?
