Github user jvwing commented on the issue: https://github.com/apache/nifi/pull/2291 @baank - thanks for the update, I think we're almost done. Two things: 1.) I still see a checkstyle warning for nifi-aws-processors: > [INFO] --- maven-checkstyle-plugin:2.15:check (check-style) @ nifi-aws-processors --- [WARNING] src/test/java/org/apache/nifi/processors/aws/s3/TestPutS3Object.java[27:8] (imports) UnusedImports: Unused import - com.amazonaws.services.s3.model.CryptoConfiguration. Are you able to run the full build with `mvn clean install -Pcontrib-check` or otherwise run the checkstyle:check task? 2.) We still have property descriptors in EncryptedS3PutEnrichmentService that specify expression language, but are not evaluating EL (KMS_KEY_ID, CUSTOMER_KEY). Did you mean to change those also?
