Possible issue with default patterns and "license" keyword

[mrapczynski]

I have been using Modclean ^3.0.0-beta.1 as part of a AWS Lambda packaging process to remove excess junk from the final .zip file prior to uploading to AWS for deployment.

However, at times, I've been chasing a weird problem where the .zip is uploaded with a damaged copy of the AWS Node.js SDK package. After stepping through each task on my build, I found out Modclean is the most likely culprint.

Note how licensemanager.js gets tossed, and unfortunately the AWS SDK fails to load because files are missing.

I looked at the default safe patterns, and it does not seem like the license term is treated with a wildcard, and yet it appears any file with the word license as part of the name get tossed.

Am I misunderstanding something?

modclean has default pattern license files to be cleaned. so file will be deleted.

I have a similar issue with src/languages/makefile.js from highlightjs being removed which breaks modules relying on it when running in AWS lambda.
