Sorry for the delay to look into this gd_sfc
I remember merging a pull request where the contributor changed that pattern, to use [ant like patterns](https://ant.apache.org/manual/dirtasks.html).
Just tested and confirmed it has been fixed. Created a freestyle job, with the following shell producing tap streams.
cat > myfilewithnoextension <<EOF
ok 2 # a comment
cat > anotherfile <<EOF
Then added the tap plug-in post build step, with the following pattern to find test results: **/file. Worked as expected.
