I have xml file names such as 1[.xml and CUP-[3000011769]-20180208142225.xml.

It is taking "[" bracket as regular expression. How to disable regular expression at FileMask.

Hi,

you may uncheck the "Use Perl5 Regex Expressions as Filemask" and it will only take 2 wildcard characters: "*" for anything and "?" for a single character.

Regards

Although i uncheck "Use Perl5 Regex Expressions as Filemask", it is not working. It catches bracket "[" as expression. I want to delete by current file name "((String)globalMap.get("tFileList_1_CURRENT_FILE"))".

You're right, my bad. It seems that when unchecking, it uses this library to convert to Perl5 regex.

And according to the documentation, it support brackets notation from the Unix shell.

Unless you want to update the default component, I think you will have to work on the filename.

You might either escape only brackets (.replaceAll(...)), or you can use a more generic method such as Pattern.quote.

Can you explain more on how to do it? Any way to disable regular expressions?

You can use this in the filemask :

java.util.regex.Pattern.quote(((String)globalMap.get("tFileList_1_CURRENT_FILE")))

This command will escape characters from the Filename.

It produces an escaped RegEx so don't forget to tick the "Use Perl5 Regex Expressions as Filemask" checkbox
