Long pathnames on windows platforms cannot be deleted
-----------------------------------------------------
Key: MCLEAN-26
URL: http://jira.codehaus.org/browse/MCLEAN-26
Project: Maven 2.x Clean Plugin
Issue Type: Bug
Affects Versions: 2.1.1
Environment: Windows, JDK1.5 Update 7,
Reporter: V. B.
Priority: Minor
Attachments: MCLEAN-file-management.patch
NOTE: Could not find a specific project for file-management and since this
project is getting affect by issue in file-management, I am reporting this
problem and its solution here.
When projects reside in directory structure that causes absolute pathnames to
go beyond 248 (maybe 260 on some Java versions) characters, files cannot be
deleted on Windows platform.
On further investigation, the root cause was the
org.apache.maven.shared.model.fileset.util.FileSetManager.delete method's
failure to successfully delete the class file in projects' target directory.
Caused by: java.io.IOException: Unable to delete file <class-file's very long
pathname>

This can be fixed by getting a canonical file from the specified file on
failure and then attempting a delete as is apparent from the attached patch to
file-management dependency's source:
groupId: org.apache.maven.shared
artifactId: file-management
version: 1.0
