[Declarative Pipeline] default params not working after checkout

[Dan Tran]

Hi

My Jenkinsfile has a few parameters with default values and are fed into  maven step  via -Dxxx=${param.yyy}

the Maven job bails right after the first invocation after checkout from git but work on subsequent 'build with parameters'

here is the error: 

[Pipeline] End of Pipeline
groovy.lang.MissingPropertyException: No such property: source for class: groovy.lang.Binding
	at groovy.lang.Binding.getVariable(Binding.java:63)

anyone sees this? should I open a bug?

Thanks

This is using param.xyz? That should be getting the default value - if it's not, definitely open a JIRA.

false alarm, one of my -Dxxx=${params.yyy} did not use 'params.' (ie ${yyy}) The error could have been better.
