Maven 2 Checksum Plugin

 This plugin provides the capability validate and generate checksums
 of the project dependencies against a checksum file that is included
 as part of the project.
 
 By including the dependency checksums as part of your project source, 
 you can detect any malicious tampering of artifacts that are downloaded 
 from third party repositories.

* Goals Overview

  * {{{validate-checksums-mojo.html}checksum-maven-plugin:validate}} is bound to the <<<validate>>> phase and
  is used to validate or generate the Project dependencies against the checksum.txt file.

* Usage

  Instructions on how to use the Checksum Plugin can be found in the
  {{{usage.html}usage}} page.
  
* Checksum File Format

  The checksum.txt file is a property file consisting of property keys in 
  the '<<<$groupId/$artifactId-$version.$type>>>' format and key values being 
  using '<<<|>>>' separated list of checksum values.  A wild card, '<<<*>>>', may be 
  used for the version or checksum.  Wild cards are needed if the project is 
  building against a SNAPSHOT dependency who's checksum changes too often.  
  The wild card is also needed for dependencies who's version number changes 
  as part of the release process.
  
  Example checksum.txt file:
