S3PutObjectRequestToV2 recipe fails with NoClassDefFound error when migrating getObjectMetadata to AWS SDK v2

[danish-kamal-sophos]

I am trying to migrate a codebase which has the following method:

public String getS3ObjectMd5(String keyName)
    {
        try
        {
            return _s3Client.getObjectMetadata(_s3BucketName, keyName).getETag();
        }
        catch (SdkClientException ex)
        {
            log.error("Error while getting MD5 checksum for S3 object: {}", keyName, ex);
            return null;
        }
    }

However, when I run the AWS SDK v2 migration recipe using an init script:
./gradlew --no-daemon -Dorg.gradle.jvmargs=-Xmx4G -Dfile.encoding=UTF-8 --init-script migrate_aws_sdk.gradle rewriteDryRun
the software.amazon.awssdk.v2migration.S3PutObjectRequestToV2 recipe errors out with message:

Execution failed for task ':rewriteDryRun'.

Has anyone else come across this issue. I think the issue is at this line where the cast should be into the type J.MethodInvocation instead of J.Identifier.
