How do you add Resource Options to a resource in JAVA CDK

[ygoodmn]

JAVA CDK version 0.9.2

Unable to see CreationPolicy or UpdatePolicy when running 'cdk synth' on the following code attached to the autoscaling Resource:

How do you attach it, with dependsOn you have an addDependency, but on see a getOptions() then a setCreationPolicy, but do not see anything in the 'cdk sythn'

1. Code

2. Output from Synth

3. Code:

        AutoScalingGroupResource autoScalingGroupResource = new AutoScalingGroupResource(this, "AutoScalingGroup",
                AutoScalingGroupResourceProps.builder()
                        .withAutoScalingGroupName(new FnSub("SMS-${ProjectID}-ServerGroup"))
                        .withLaunchConfigurationName(launchConfigurationResource.getLaunchConfigurationName())
                        .withMinSize(minSizeParam.getValue().toString()) //
                        .withMaxSize(maxSizeParam.getValue().toString()) //
                        .withDesiredCapacity(desiredCapacityParam.getValue().toString())
                        .withTargetGroupArns(Collections.singletonList(targetGroupResource.getTargetGroupArn()))
                        .withVpcZoneIdentifier(subnets)
                        .withHealthCheckType("ELB")
                        .withHealthCheckGracePeriod(120)
                        .build());

        //TODO  DOES not attach the Policies
        autoScalingGroupResource.getOptions().setCreationPolicy(CreationPolicy.builder().withResourceSignal(ResourceSignal.builder().withCount(0).build()).build());
        autoScalingGroupResource.getOptions().setUpdatePolicy(UpdatePolicy.builder().withAutoScalingRollingUpdate(AutoScalingRollingUpdate.builder()
                .withMinInstancesInService(1)
                .withMaxBatchSize(1)
                .withPauseTime("PT15M")
                .withWaitOnResourceSignals(true)
                .build()).build());

        ResourceOptions resourceOptions =  ResourceOptions.builder()
                .withCreationPolicy(CreationPolicy.builder().withResourceSignal(ResourceSignal.builder().withCount(0).build()).build())
                .withUpdatePolicy(UpdatePolicy.builder().withAutoScalingRollingUpdate(AutoScalingRollingUpdate.builder()
                        .withMinInstancesInService(1)
                        .withMaxBatchSize(1)
                        .withPauseTime("PT15M")
                        .withWaitOnResourceSignals(true)
                        .build()).build())
                .build();

Yes, that seems like a bug. Thanks for reporting. We're going to have to investigate this.

In the mean time, have you considered using the AutoScalingGroup L2 resource (as opposed to AutoScalingGroupResource)?

This is a bug in the jsii kernel: In the javascript world, the call to getOptions returns an object literal (as opposed to a class instance) that adheres to a particular interface, and this causes the kernel to return a copy of this (instead of a reference to it).

I've created aws/jsii#248 on jsii to track the fix there (will update this issue once resolved).

Thanks for reporting. Closing this as it's being tracked elsewhere.
