How to create custom objects/setting using Apache Ant in Salesforce?

Hi Kapil,

we cannot create objects using Apache ant but we can migrate objects from one salesforce org to another
Following are the steps to migrate objects from one org to another:
1.In the build.properties specify the username and password of the source and destination org.
2.In the package.xml specify the name of object you want to retrieve.
3.your build.properties look like this
# build.properties
#

# Specify the login credentials for the desired Salesforce organization
sf.username=sourceorg@salesforce.com
sf.password=xxxxxxxxxxxxxxxxx

sf1.username=destinationorg@salesforce.com
sf1.password=xxxxxxxxxxxxxxxxx
#sf.sessionId = <Insert your Salesforce session id here. Use this or username/password above. Cannot use both>
#sf.pkgName = <Insert comma separated package names to be retrieved>
#sf.zipFile = <Insert path of the zipfile to be retrieved>
#sf.metadataType = <Insert metadata type name for which listMetadata or bulkRetrieve operations are to be performed>

# Use 'https://login.salesforce.com' for production or developer edition (the default if not specified).
# Use 'https://test.salesforce.com for sandbox.
sf.serverurl = https://login.salesforce.com
sf1.serverurl = https://login.salesforce.com

sf.maxPoll = 120
sf1.maxPoll = 120
# If your network requires an HTTP proxy, see http://ant.apache.org/manual/proxy.html for configuration.
#

4.your package.xml look like this

<?xml version="1.0" encoding="UTF-8"?>
<Package xmlns="http://soap.sforce.com/2006/04/metadata">
<types>
<members>specify the name of custom object</members>
<name>CustomObject</name>
</types>
<version>40.0</version>
</Package>
5.command to retrieve object
ant retrieveUnpackaged

6.command to deploy object
ant deployUnpackaged

Hi,

Apache Ant is a Java library and command-line tool. Ant was originally used for building Java applications, but Salesforce.com supplies extra libraries to enable Ant to move metadata between a local directory and a Salesforce org. The Ant-Salesforce Libraries are known as the Force.com Migration Tool. There are many methods for migrating metadata (change sets, for example).

<?xml version="1.0" encoding="UTF-8"?>
<Package xmlns="<a href="http://soap.sforce.com/2006/04/metadata" target="_blank" rel="nofollow">http://soap.sforce.com/2006/04/metadata</a&gt;">
<fullName>test</fullName>
<types>
<members>testss__c</members>
<name>CustomObject</name>
</types>
<types>
<members>testss__c.fields__c</members>
<name>CustomField</name>
</types>
<types>
<members>testss__c.fields2</members>
<name>CustomField</name>
</types>
<version>20.0</version>
</Package>

Hope this helps.
