phreed opened a new issue #5725: Relax PULSAR_HOME requirement.
URL: https://github.com/apache/pulsar/issues/5725
 
 
   **Is your feature request related to a problem? Please describe.**
   
   I am developing gradle plugins for nifi and pulsar. The main gradle task for the nifi-gradle-plugin is to produce nar files from gradle. The main task for the pulsar-gradle-plugin is to run sink-connectors, source-connectors, functions as localrun processes. This makes debugging of these components from withing IDE (idea) simpler. As I develop these tasks I am finding small things in pulsar that get in the way. 
   
   **Describe the solution you'd like**
   
   In https://github.com/apache/pulsar/blob/branch-2.4/pulsar-functions/localrun/src/main/java/org/apache/pulsar/functions/LocalRunner.java#L456
   There is a call to System.getenv("PULSAR_HOME") rather than  System.getProperty("PULSAR_HOME") . This makes it impossible to set PULSAR_HOME from within java, which is something I would like my plugin to be able to do.
   
   **Describe alternatives you've considered**
   
   Setting the PULSAR_HOME in my .bash_profile and logging out and back in.
   
   **Additional context**
   
   This may be better handled by having a custom LocalRunner.java for my gradle plugin.
   This may actually be the best approach.
   In that case I would like to see the LocalRunner be split in two. 
   1. The command line tool using JCommander
   2. Something like the following which is called by (1)
   [PulsarLocalRunner.kt.txt](https://github.com/apache/pulsar/files/3881675/PulsarLocalRunner.kt.txt)
