Provide the means to easily create a clean .zip file from the dev guide's solution SDK.
- No files downloaded from Ivy should be included in the .zip file. The build framework should provide the means to easily remove them and/or exclude them from the .zip.
- All plugin projects should be "cleaned" before creating the .zip file.
- The .zip file name should distinguish it from other SDKs that Liferay provides. For example, dev-guide-plugins-sdk.zip.
