Multitarget applications are defined in a development descriptor required for design-time purposes.
The development descriptor (mta.yaml) defines the elements and dependencies of a Multitarget application (MTA) compliant with the Cloud Foundry environment.
The MTA development descriptor (
mta.yaml) is used to generate the deployment descriptor (mtad.yaml), which is required for deploying an MTA to the target runtime. If you use command-line tools to deploy an MTA, you do not need anmta.yamlfile. However, in these cases you have to manually create the deployment descriptor (mtad.yaml) file.
For more information about the MTA deployment descriptor, see Defining Multitarget Application Deployment Descriptors for Cloud Foundry.
