                                        throws IOException

Here is the patch applying algorithm. 1) Creates a patch0000 (if it does not exist) inside the patches directory. Backup all the bundles in the plugins directory 2) Before applying patches on components/patches directory apply servicepacks on components/servicepacks directory 3) Then copy remaining patches which not contain on servicepacks patchxxxx to the plugins folder.

servicepackDir - parent servicepack directory "repository/components/servicepacks"

patchesDir - parent patch directory "repository/components/patches"

pluginsDir - plugin directory "repository/components/plugins"

Throws:

IOException

source - servicepack directory

target - plugin directory

Throws:

IOException
