The Ant Migration Tool is retired with Spring ’24. The tool continues to
function for future API versions but isn’t updated with new functionality and isn’t supported.
To manage metadata changes, switch to Salesforce CLI for a modern, supported developer
experience.
To retrieve Lightning Platform components:
- Open a command prompt.
- Run Ant by specifying a target name in build.xml. If it’s the first time
you’re running Ant, use ant retrieveUnpackaged to
retrieve unpackaged components specified in package.xml.
- The sample build.xml contains some useful targets for various
retrieve() and deploy() options that
you can modify or use as is. To see a list of all your named targets in build.xml,
enter ant -p at the command line.
- You can deploy or retrieve up to 10,000 files at once. The maximum size of the deployed or
retrieved .zip file is 39 MB. If the files are uncompressed in an unzipped folder, the
size limit is 600 MB or 629,145,600 bytes. The size limit in bytes is calculated as 600 x
1024 x 1024. If you’re working with many components, use the listMetadata target to identify the subset of
files that you want to retrieve. You can also retrieve batches of components as described
in Retrieving Components in Bulk.
