[MASSEMBLY-505] Feature Request: useStrictFiltering option for FileSets

**[John Dennis Casey](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=jdcasey)** opened **[MASSEMBLY-505](https://issues.apache.org/jira/browse/MASSEMBLY-505?redirect=false)** and commented

**NOTE:** This is a clone of MASSEMBLY-488. The original issue will be closed Won't Fix, since the plexus-utils class DirectoryScanner, which is the core of the FileSet functionality, doesn't support strict include/exclude filtering.

This issue is a feature request to have that added.

I'm trying to turn on useStrictFiltering in a fileSet in an assembly
descriptor, but maven doesn't fail when the file does not exist. Here
is an example of what the assembly descriptor looks like:

\\
\
\tar.gz\
\
\
\
\true\
\src/main\
\
\nonexistant.txt*\
\
\
\
\
Running "mvn package" happily produces a tarball with no indication that anything is wrong.

Start with the assembly descriptor's FileSet handling and the plexus-utils DirectoryScanner, which the issue identifies as the core limitation; use fail_strictfiltering.zip and run the shown mvn package scenario. Done means a missing strict include causes the Maven Assembly Plugin build to fail for FileSets, rather than silently producing an incomplete tarball.
