How do I resolve java.lang.ClassNotFoundException error for HistoricalEstimateStatisticValueResolver

I am creating a custom REST Endpoint using the AWESOME ScriptRunner plugin but I am running into a ClassNotFoundException.

I am trying to extend the current JIRA Velocity REST End Point to return more than 7 sprints.  I was able to find the current Velocity REST End Point and find where the Sprint Count is hard coded to 7.

Any help to resolve the CLASSNotFoundException would be appreciated!

Hi Erik.

May I recommend that when using groovy and defining classes, if you are not using any of their methods, you use the keyword "def" rather than the type. It really helps with dependency problems sometimes.

In this case you don't even need to have the class imported, since your object isn't being called at all, and it could be resolved dynamically.

Can you try and see if this works?

That did the trick!! Thanks!!

 

I seem to get an exception during debugging but I do get the data I need. 

 

Thanks again!

Hi,

Trying to:

import com.onresolve.scriptrunner.runner.customisers.JiraAgileBean

 

What should get added to pom.xml? 

nvm.

<dependency>
<groupId>com.onresolve.scriptrunner</groupId>
<artifactId>groovyrunner-5.2.1</artifactId>
<version>5.2.1</version>
<scope>system</scope>
<systemPath><path_to_jar>/groovyrunner-5.2.1.jar</systemPath>
</dependency>
