    Salesforce Organization Destroy - Ant Script

This script searches and destroys (most) metadata in an organization. Use cases include ISV package development and testing within Developer Edition and Sandbox environments.
Usage: (paste the macrodef XML into your build file)
<target name="destroy">
    <destroy
        username="${sf.username}"
        password="${sf.password}"
        serverurl="${sf.serverurl}"
    />
</target>

It forces an input prompt for the URL and username:

THIS TASK IRREVERSIBLY DESTROYS ALL METADATA. ARE YOU SURE?
(https://test.salesforce.com/?un=username@organization...)


How does it work?

First sf:describeMetadata determines the "shape" of the organization. Then, all components are listed in turn from each metadata type. The results are appended in a destructiveChangesPost.xml manifest which gets deployed back over the org.
Does it unlink dependencies?

Yes. Dependencies are cleared in one metadata deployment. It takes advantage of destructive changes POST-deploy, which clears everything in a single transaction. Specifically:

Page Layouts are cleared of custom buttons and custom links
Sites are cleared of static resources and visualforce pages
Profiles are cleared of default application visibilities
Roles are cleared of their parent hierarchy association

What cannot be destroyed?

Some metadata types such as Assignment Rules act as permanent containers for the individual rules. Or others such as Record Types do not support delete operation. These fall into a few different categories.
Rules whose child types CAN be destroyed independently:

Assignment Rules
AutoResponse Rules
Escalation Rules
Matching Rules
Sharing Rules
Workflow Rules

Standard component types which cannot be destroyed:

Field
Object
Layout
Profile
App Menu
Matching Rule
Clean Data Service
Business Process as in Case record type
Community as in Idea Zone, not to be confused with "Network"

Others:

Force.com Sites (permanent and cannot be destroyed)
Flow (the flow definitions CAN be destroyed independently)
Certificate (left intact to avoid interfering with Environment Hub)
CustomObjectTranslation (each entry is maintained when the object)
InstalledPackage (best uninstalled via UI which nags about extensions etc)
RecordType (can be destroyed via UI which involves an asynchronous background process)

The other unsupported metadata types are well documented in the Metadata API guide
What about Custom Metadata Types?

This script destroys both the named metadata records, and also the custom definition.
