+  The above example effectively cuts away the prefix <<<x.y/z/>>> of each
unpacked file's path, using a regular
+  expression and a replacement expression. Two tricks need to be used here: First, the regular
expression uses <<<\Q>>>
+  and <<<\E>>> to demarcate pattern quoting, as the dot (<<<.>>>)
is special character in a reqular expression. Second,
+  due to a restriction of Maven's POM syntax, the replacement cannot be empty (this would
skip the file). Instead a
+  dot-slash (<<<./>>>) replacement is used, which is effectively a no-op
for paths segments.
+
+  Any Plexus File Mapper (i. e. implementation of the interface
+  <<<org.codehaus.plexus.components.io.filemappers.FileMapper>>>) can be
used, but there are three particularly useful.
+
+  The Regular Expression Mapper is useful to modify or cut away prefixes or suffixes, or
to rewrite file extensions:
+
++---+
+ [...]
+ <org.codehaus.plexus.components.io.filemappers.RegExpFileMapper>
+   <pattern>[...]</pattern>
+   <replacement>[...]</replacement>
+ </org.codehaus.plexus.components.io.filemappers.RegExpFileMapper>
+ [...]
++---+
+
+  The Prefix File Mapper is useful to add prefixes:
+
++---+
+ [...]
+ <org.codehaus.plexus.components.io.filemappers.PrefixFileMapper>
+   <prefix>[...]</prefix>
+ </org.codehaus.plexus.components.io.filemappers.PrefixFileMapper>
+ [...]
++---+
+
+  The Flatten File Mapper removes the path completey, effectively putting all files in the
same folder:
+
++---+
+ [...]
+ <org.codehaus.plexus.components.io.filemappers.FlattenFileMapper/>
+ [...]
++---+
+
+  When multiple file mappers are given, the list gets executed from top to bottom. This might
improve readability of
+  the overal rewriting action compared to using a singular (typically complex) regular expression.

>                 Key: MDEP-628
>                 URL: https://issues.apache.org/jira/browse/MDEP-628
>             Project: Maven Dependency Plugin
>          Issue Type: New Feature
>          Components: unpack, unpack-dependencies
>    Affects Versions: 3.1.1
>            Reporter: Markus Karg
>            Priority: Major
>              Labels: FileMapper, Mapping, Path
>
> The new parameter {{fileMappers}} (default: {{null}}) can be set to an implementation
of the {{org.codehaus.plexus.components.io.filemappers.FileMapper}} interface to rewrite
the target path of each unpacked file.
> This is useful in case prefixes of target files names within the target directory shall
be added (using {{PrefixFileMapper}}), changed or omitted (using {{RegExpFileMapper}}).
