Nifi throws an exception on startup.

[n2mp60]

Followed the instructions in the README.md file. Nifi won't start as there's no properties file found. NifiProperties.java expects the system property, PROPERTIES_FILE_PATH, to be set on startup. So two problems here - 1. System property is not set, but README.md could be updated to include this as a necessary setting in the Eclipse Run configuration, and 2. nifi.properties file needs to be generated as part of the Eclipse project files.
One other aside, there isn't a log4j properties file so you don't see the error message thrown.

Yes, that is correct. I need to update the docs. There is a missing step where when you configure runnable you also have to provide -D for nifi.properties.
Also, keep in mind that you need to update to the latest version in build.gradle (e.g., 1.0.0-snapshot)

I'll find time to polish the docs

I've got the -D-Dnifi.properties.file.path included but I get:

17:00:24,956  INFO main nifi.NiFi:88 - NiFi started without Bootstrap Port information provided; will not listen for requests from Bootstrap

And I see nifi-nar-utils jar in the referenced libraries. Any idea what's wrong?

@cupdike I've got the same problem, Do we need change the nifi-runtime jar's version?
