I have a question regarding parameter expansion in Groovy. I have a variable called : ${My_Version} now I have seen that you can only use the first 4 digits of the variable with the following possibilities : ${My_Version[0..4]}.

Now I have the following problem I would like to use a Regex parameter to filter out software versions like 10.0.0. The corresponding Regex parameter is : ^(\d+.)?(\d+.)?(*|\d+)[;]

How can I use this Regex parameter from this variable. Thank you for your help.

I've been thinking about something like : ${My_Version[^(\d+\.)?(\d+\.)?(\*|\d+)[;]]}

Do you mean like `^\d+\.\d+\.\d+$` ? – The fourth bird Oct 21 '19 at 06:57
