RegExp for File URL

Question

I write a RegExp for validate a file URL

file:/{2,3}[a-zA-Z0-9]*\\|?/.*

for URL like

file:/D:/workspace/project/build/libs/myjar-1.0.jar

But doesnt work, am looking for a pattern that matches only URL like this,no other.

Pattern Will return false URLs like

file:/workspace/project/build/libs/myjar-1.0.jar and file:/D:/workspace/project/build/libs/myjar-1.0 are will not match

please help

What context is this?? Because if it has no context to match it just /file\:.*/i — Jorge Campos

Complete question rewrite

Given the OP's updated criteria, the regex you're looking for is file\:\/\w\:\/[^\s]*\.jar; ensure you enabled g (global) and i (case-insensitive) modifiers.

See a working example on Regex101

Saw that, hence my stating that given your context, @JorgeCampos answer is the most suitable. If you have other criteria (e.g. disallow spaces, require colon) that obviously changes the expression.

problem is when i validate the url @JorgeCampos expression is return true when the url is 'file:/workspace/project/build/libs/myjar-1.0.jar' and 'file:/workspace/project/build/libs/myjar-1.0'

I see your updates to the question, standby while I edit this answer to reflect the 'false' matches.

If there is no context or rule your regex should be:

/file\:.*/i

When you sai like this, I ask Like this what? same path? same number of directories? Just from D: directory? Just *.jar files? You see, still much vague
