Not able to create task from xl-deploy cli

Question

I want to trying to deploy the dar file using cli. I had set up the cli on one of our build machine.

I have gone through the document as well( https://docs.xebialabs.com/xl-deploy/4.5.x/climanual.html ). But when I am running the below code. I am getting an error on the step where task is getting created.

# Import package 
deployit> package = deployit.importPackage('demo-application/1.0') 
# Load environment 
deployit> environment = repository.read('Environments/DiscoveredEnv') 
# Start deployment 
deployit> deploymentRef = deployment.prepareInitial(package.id, environment.id) 
deployit> deploymentRef = deployment.generateAllDeployeds(deploymentRef) 
deployit> taskID = deployment.deploy(deploymentRef).id 
deployit> deployit.startTaskAndWait(taskID) 

Error:

javax.ws.rs.ProcessingException: com.thoughtworks.xstream.converters.ConversionException:

cause-exception     : java.lang.NullPointerException

How can I fix this issue?

Answer 1

Here is an Example in which you can start deployment task, check each step status and print logs for Failed ones,

# Load package
package = repository.read('Applications/TestApps/1.0')

# Load environment
environment = repository.read('Environments/TestingEnv')

# Start deployment
deploymentRef = deployment.prepareInitial(package.id, environment.id)
depl = deployment.prepareAutoDeployeds(deploymentRef)
task = deployment.createDeployTask(depl)
deployit.startTaskAndWait(task.id)

# Check on deployment errors

steplist = tasks.steps(task.id)
for s in steplist.steps:
    print(' Step: ' + s.description)
    print(' Status: ' + str(s.state))
    if str(s.state) == 'FAILED':
        print('ERROR ' + s.log)

Also you can have a look on XLDeploy log file located at XLDeploy server under " XLD_INSTALL_HOME/log/deployit.log " to get more details in case of errors.
