> Reporter: Raphael von der Grün
> Assignee: Claude Warren

> Run the following command in the root of the `rat` repo:
> {noformat}
> java -jar apache-rat-0.14-20191120.132901-66.jar -e "*.txt" -d
> apache-rat-core/src/test/resources/violations{noformat}
> This will give the following output on `stderr`:
> {noformat}
> Will skip given exclusion '*.txt' due to
> java.util.regex.PatternSyntaxException: Dangling meta character '*' near
> index 0
> *.txt
> ^
> {noformat}
> Furthermore, `bad.txt` will NOT be excluded from the license check.
> The error that causes this is thrown in [line 132 of
> `org.apache.rat.Report.java`|#L132]]. The reason is simple: any glob pattern
> that starts with `*` or `?` is not a valid regex. When Line 132 throws, the
> next two lines will also be skipped, so the pattern will not be added at all.
> Unfortunately, a solution to this problem is not so simple. In `v0.12` the
> `-e` option always added wildcard filters while `-E` always added regex
> filters. The documentation still states the same in the latest `v0.14`
> snapshot. Beginning with `v0.13` the code tries to add any exclude rule as
> three different filters. I believe this approach is inherently flawed.
> Firstly, the `new NameFileFilter(exclusion)` is redundant if we also add `new
> WildcardFileFilter(exclusion)`. The files matched by the `NameFileFilter` are
> a subset of those matched by the `WildcardFileFilter` since any magic
> character (i.e. `?` or `*`) in `exclusion` also matches itself when used in a
> `WildcardFileFilter`.
> So let's assume we only register the `WildcardFileFilter` and the
> `RegexFileFilter`. Even if we properly add patterns as wildcard filters that
> are not a valid RegEx, there are still patterns where we cannot decide what
> the user's intention was. Consider the pattern `bi.ini`. Should it be
> interpreted as a wildcard pattern and match only itself or should it be
> interpreted as a regex and also match `bikini` for example?
> My recommendation for a quick patch solution would be to go back to the
> exclusion behavior of `v0.12`.
> Beyond that, the nicest solution IMHO would be support for ignore files with
> the same semantics as `.gitignore` (via `-E`) and support for giving extended
> shell globs via `-e`.
