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

Erik Saline
Erik Saline August 31, 2017

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?

Hi Erik,

 

Can you provide us the sample output for this script?  Can we able to extract completed and committed story points in jira velocity?

 

Appreciate your help
