Issues we may get during the deployment through wldeploy ant task

BUILD FAILED
weblogic.management.ManagementException: [Deployer:149163]The domain edit lock is owned by another session in non-exclusive mode - this deployment operation requires exclusive access to the edit lock and hence cannot proceed. If you are using "Automatically Aquire Lock and Activate Changes" in the console, then the lock will expire shortly so retry this operation.

Solution 2 : Wait until Lock& Edit available or release the Configuration changes to obtain the lock.

Solution 2 : use the usenonexclusivelock="true" to build.xml to avoid the error.

Note: If we use this option  ant will not through error but gives the warning as 

[wldeploy] [BasicOperation.execute():445] : Initiating deploy operation for app, example-App , on targets:

 [wldeploy] [BasicOperation.execute():447] :    server-name

 [wldeploy] Task 14 initiated: [Deployer:149026]deploy application example-App on server-name.

 [wldeploy] Operation is pending and will be activated or cancelled when the ongoing edit session is activated or cancelled.

• Once the activate changes done deployment done other wise changes will not reflect.
