Jenkins pass variable into groovy script

Question

Hi I need to pass a variable from select into the groovy script and I haven't a clue how to do it in variable bindings, anyone has an idea how to do it?

I tried with:

version=version

version=$version

version=${version}

version="${version}"

Answer 1

If you are going to use ${ ... } Notation you should enclose it double quotes, ie:

versionVar = "${version}"

The other think that keeps bothering me is that you are using the same variable name. I haven't tried but I think that using the same name you could are trying to use the same variable.

Answer 2

Where is the 'version' variable came from?
If you are trying to use Environment variables, then you should try like,

version = env.version
