While you are at it… can you make it so it supports more than one file in that field, probably comma delimited? I have one JDBC driver that for whatever reason requires two separate JAR’s.

We should add expression language support to the path property if it isn't already as that makes variable registry access available which makes use of the same template or flow in different environments easier.

All jar’s in your lib directory are loaded in the classpath for all NAR’s. Personally I have three different JDBC drivers in my lib directory to make them available for whoever needs them (MS SQL, SAP Hana, Teradata, and will add Oracle soon). --Peter From: Sumanth Chinthagunta [mailto:xmlk...@gmail.com<mailto:xmlk...@gmail.com>] Sent: Thursday, August 18, 2016 8:56 PM To: users@nifi.apache.org<mailto:users@nifi.apache.org> Subject: Re: adding dependencies like jdbc drivers to the build It would be nice if we support relative paths for driver jar.

If you look in the lib directory you will see all the NAR files, each NAR has one or more components along with all of the other JARs it needs, and each NAR has isolated class loading so that they will not interfere with each other. You would need to figure out which NAR you are dealing with and add a dependency to one of the poms related to that NAR. -Bryan On Thu, Aug 18, 2016 at 4:33 PM, Tom Gullo <tomgu...@gmail.com<mailto:tomgu...@gmail.com>> wrote: If I want to add a jdbc driver or any third party dependency where should I add that dependency in the Maven build for Nifi?
