I'm tryind to purge cache during my build process after uploading files to spaces cdn. But can't do it with amazon sdk java version 2.

I have this article

https://developers.digitalocean.com/documentation/changelog/api-v2/support-for-spaces-cdn-endpoints/

but can't understand how to do it with amazon sdk. Should I user CloudFrontClient or something other?

What should I do, I wrote this code, but it fails? ( What shoud i use for distributionId?

def cfc = CloudFrontClient
.builder()
.credentialsProvider(StaticCredentialsProvider.create(AwsBasicCredentials
.create(
digitalOceanProps.getProperty("Cdnkey"),
digitalOceanProps.getProperty("Cdnsecret"))))
.region(Region.of("sfo2"))
.endpointOverride(URI.create("https://sfo2.digitaloceanspaces.com"))
.build()

        def paths = Paths.builder()
                .items("/resources")
                .quantity(1)
                .build()

        def invalidationBatch = InvalidationBatch.builder()
                .paths(paths)
                .build()

        def invalidationRequest = CreateInvalidationRequest.builder()
                .distributionId("cdn")
                .invalidationBatch(invalidationBatch)
                .build()

        CreateInvalidationResponse ret = cfc.createInvalidation(
                invalidationRequest
        )
