Returns:

retrieveDeploymentSHA

public String retrieveDeploymentSHA(File deployment,
                                    File resourceDataDirectory)

Retrieves SHA256 for the deployment. If this is an exploded deployment and SHA256 is missing from the data directory then compute the SHA256 and save in the data directory.

originalArchive -

deployment -

resourceId -

dataDirectory -

Returns:

saveDeploymentSHA
