How can I use addProjectAssociations() to update the Issuetype scheme of a list of projects.

[Jeremy Jedlicka]

I have a list of over 100 projects that are earmarked for archival and are the only projects in the applicable Issue Type Scheme.  I'm trying to move these projects into a similar scheme that doesn't require any Issue mapping. 

Trying to use Scriptrunner I'm attempting to use the method: 

addProjectAssociations()

 found in the documentation here: IssueTypeSchemeService (Atlassian JIRA - Server 8.0.0 API), but I keep getting a "groovy.lang.MissingMethodException: No signature of method:" error.

Any help would be appreciated.

Here is my code for reference:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.issuetype.IssueType
import com.atlassian.jira.project.Project
import org.apache.log4j.Category

def projectManager = ComponentAccessor.getProjectManager()
def issueTypeSchemeManager = ComponentAccessor.getIssueTypeSchemeManager()
def loggedInUser = ComponentAccessor.jiraAuthenticationContext.loggedInUser
def Category log = Category.getInstance("")

log.setLevel(org.apache.log4j.Level.DEBUG)

def projects = "RDCALERTS"

def serviceOutcome = issueTypeSchemeManager.addProjectAssociations(loggedInUser, 21300, projects)

if (serviceOutcome.isValid()) {
    log.info("Issue Scheme Updated")
} else {
    log.error("Update failed: ${serviceOutcome.getErrorCollection().errors}")
}

Welcome to the Atlassian Community!

I think that's because you are passing a string into the call with "projects".  The call is expecting a list (even if it is a list of one item!)

It doesn't seem to matter, I can use 

def projects = ["ProjectID"] 

and it will still give me an error.

It says the proposed solution is to:
Possible solutions: addProjectAssociations(com.atlassian.jira.issue.fields.config.FieldConfigScheme, java.util.Collection)

but this isn't a field configuration change, so Im not sure why it wants me to use that.

That is not an array or collection.

Try forcing the type by dropping down into Java, such as

String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
