Java Azure SDK scaleset: how to specify image version

Question

When I am scaling up a scaleset I want to specify the image version to use. Right now it always uses the latest image from the compute gallery. I think that is what this az CLI command does: az vmss update -- resource-group myResourceGroup --name myScaleSet --set virtualMachineProfile.storageProfile.imageReference.version=0.235.102011129

Now I want to do the same in Java with the Azure Resource Manager SDK. ChatGPT gave this suggestion

// Resource group and scale set names
final String resourceGroupName = "myResourceGroup";
final String scaleSetName = "myScaleSet";

// Retrieve the scale set
VirtualMachineScaleSet scaleSet = azureResourceManager.virtualMachineScaleSets()
      .getByResourceGroup(resourceGroupName, scaleSetName);

// Update the image reference version
VirtualMachineScaleSetUpdate updateParams = scaleSet.update()
      .withVirtualMachineProfileStorageProfile(new VirtualMachineScaleSetUpdateStorageProfile()
              .withImageReference(new ImageReference()
              .withVersion("0.235.102011129")))
      .apply();

But the problem is that withVirtualMachineProfileStorageProfile does not exist for scaleSet.update().

Does anyone know how to do this?

Refer this MS Document which calls Azure Resource manager API with JAVA and updates Image with specific version by accessing StorageProfile of the VMSS:-

Code Reference from MS Document:-

VirtualMachineScaleSetUpdateStorageProfile()
                            .withImageReference(new ImageReference()
                                .withId("hhhhhhhhh").withPublisher("MicrosoftWindowsServer")
                                .withOffer("WindowsServer").withSku("2016-Datacenter").withVersion("latest")
                                .withSharedGalleryImageId("aaaaaa"))
                            .withOsDisk(new VirtualMachineScaleSetUpdateOSDisk().withCaching(CachingTypes.READ_WRITE)
                                .withWriteAcceleratorEnabled(true).withDiskSizeGB(6)
                                .withImage(new VirtualHardDisk().withUri(
                                    "http://{existing-storage-account-name}.blob.core.windows.net/{existing-container-name}/myDisk.vhd"))

sample.java:-

import com.azure.resourcemanager.compute.models.*;

public final class Main {
    public static void main(String[] args) {
        VirtualMachineScaleSetUpdateStorageProfile storageProfile = new VirtualMachineScaleSetUpdateStorageProfile()
            .withImageReference(new ImageReference()
                .withId("aaaaaaaaaaaaaaaaaaa")
                .withPublisher("MicrosoftWindowsServer")
                .withOffer("WindowsServer")
                .withSku("2016-Datacenter")
                .withVersion("latest")
                .withSharedGalleryImageId("hshshs"))
            .withOsDisk(new VirtualMachineScaleSetUpdateOSDisk()
                .withCaching(CachingTypes.READ_WRITE)
                .withWriteAcceleratorEnabled(true)
                .withDiskSizeGB(6)
                .withImage(new VirtualHardDisk()
                    .withUri("http://{existing-storage-account-name}.blob.core.windows.net/{existing-container-name}/myDisk.vhd")));
    }
}
