java.util.regex.PatternSyntaxException: Unclosed character class near index 58 error

Question

When I am opening the Cucumber editor in Eclipse IDE, i am receiving the below error-

java.util.regex.PatternSyntaxException: Unclosed character class near index 58
^User Selects "([^"]*)", "([^"]*)", "([^"]*)" and "([^]*)"$

I had received this error in an earlier execution as there was a mistake in my step definition file. I have fixed that and when I trying to open the feature file again I receive this error. Can someone help me to resolve this.The feature file and programs are attached. Even a rerun is not working.

Screenshot of error from Eclipse IDE while opening a feature file: Cucumber editor error in eclipse

Answer 1

I believe this part is wrong:

"([^])"$ - in the end of your regex

This makes no sense [^] - it means charcters that are not - and you are not saying what they shouldn't be :) For example [^a] will be charcters different from 'a' or as you have written before that [^"] - not a quote. But [^] is an error
