If you look at the Java docs https://www.javadoc.io/doc/org.apache.nifi/nifi-processor-utils/1.0.0 and then https://www.javadoc.io/doc/org.apache.nifi/nifi-processor-utils/1.1.0 you will notice that the StandardValidators have been removed.
I would like to know why this has been done (maybe it is deprecated)? Has it been moved to another library?
@Pierre le Roux It's still there but it is in a different package now [1,2]. It looks like javadoc.io has an incomplete index of the docs so you aren't seeing the docs for any of nifi-commons which is where it is now.
