   Hi,
   
   I did a minimal test to reproduce and describe the issue:
   
   I have a directory containing .* resources (for example ".svn") let's say `C:\tmp\svn_checkout`
   I create a project with a minimal pom.xml :
   
   ```xml
   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
   	<modelVersion>4.0.0</modelVersion>
   	<groupId>test</groupId>
   	<artifactId>test</artifactId>
   	<name>test</name>
   	<version>1.0-SNAPSHOT</version>
   </project>
   ```
   
   In the project I create a `"target"` directory
   In the target directory I do `"mklink /J svn_checkout C:\tmp\svn_checkout"`
   So I have
   
   ```
   C:\testproject
   C:\testproject\pom.xml
   C:\testproject\target
   C:\testproject\target\svn_checkout -> C:\tmp\svn_checkout
   ```
   
   If I do `"mvn clean"` the target directory is deleted as expected, but also all my `.svn` directories under `C:\tmp\svn_checkout`
   If I have other .* files (.project, .classpath) they are deleted too.
   
   In the real life I have a custom maven plugin that creates an ear on my app server, and replaces the war files in it by junction to the war project I checkout from svn.
   I add the ear in the list of directories to be "cleaned" (by adding a \<fileset>), and I have all my `.svn` deleted on each clean.
   
   Regards,
   
   Laurent

   Fixed for java7+ users in r1631508. This issue will not be fixed for prior java versions

   It looks like it is not possible to recognize a junction with Java6 or previous version (and this plugin has recently moved to java5!).
   But there is a project called [JNA](https://github.com/twall/jna) which could help us here with [getFileAttributes()](http://twall.github.com/jna/3.4.0/javadoc/com/sun/jna/platform/win32/Kernel32Util.html#getFileAttributes(java.lang.String))
