Summary
Package extractor allows for providing filters to modify the list of files to extract. However, because the file system traversal analyzes both folders and files, patterns that specified a subfolder of a non-matching parent folder would not be traversed and would be excluded from the generated extraction. This change ensures that all folders are traversed and only files are matched against the filters.
For example, if
patternsToInclude
issrc/**/*
, files within thesrc
folder would not actually be collected, sincesrc
does not match the patternsrc/**/*
itself, even though the files and folders within do match.How it was tested
Tested locally against the project that the issue was encountered in.
