VersionManager.getVersion returns error in Behaviours

Joe Mallon

Jira 8.5.1, ScriptRunner 6.33

I have the ID of a version and am trying to get its name, but Behaviours doesn't respect the getVersion() method.

Script:

import com.atlassian.jira.component.ComponentAccessor

def fixV = getFieldById(getFieldChanged())
def fixVValue = fixV.getFormValue()

def VersionManager = ComponentAccessor.getVersionManager()
def newFixVersion = VersionManager.getVersion(fixVValue)

Error on last line:

Cannot find matching method com.atlassian.jira.project.version.VersionManager#getVersion()

 getVersion is a method of VersionManager:

https://docs.atlassian.com/software/jira/docs/api/8.5.1/com/atlassian/jira/project/version/VersionManager.html#getVersion-java.lang.Long-

Why does Behaviours not respect that method?

If you actually tried to execute the behavior and looked in the log file, you would see something like this:

groovy.lang.MissingMethodException: No signature of method: com.atlassian.jira.project.version.DefaultVersionManager.getVersion() is applicable for argument types: (String) values: [35720]

This gives more details... such that it tried to call the getVersion() method with a string (default data type returned by behaviors but the method expects a Long.

You can also easily examine the value during debugging to find what data type to expect and what conversion might be needed by putting this in your behavior:

def fixV = getFieldById(getFieldChanged())
fixV.clearHelpText()
def fixVValue = fixV.getFormValue()
fixV.setHelpText("$fixVValue ${fixVValue.getClass()}")

Then try it in an issue and you will see this below your field:

37325 class java.lang.String

Or the following if you select more than 1:

[37325, 37532] class java.util.Arrays$ArrayList

If you are confident that you will only allow one value, the fix is as simple as

def newFixVersion = versionManager.getVersion(fixVValue as Long)
