Trying to build NiFi from Dev Source

[#1]

On Mac using http://nifi.apache.org/quickstart.html. Basically, I just want to try one of the features added later than 1.0.0, so thought this would be a straightforward way to do that. Keep running into the following error:

[ERROR] COMPILATION ERROR :

Any ideas/help appreciated!

[#2 · Accepted solution]

did you do a full mvn clean?

do you have JDK 1.8 and maven 3.1 installed?

brew install protobuf

this is a helpful tool

@Timothy Spann by 'full mvn clean' -- I always did `mvn clean install` and yes to all else including double-check of:

brew install protobuf
>>Warning: protobuf-2.6.1 already installed

It worked for me

export MAVEN_OPTS="-Xms1024m -Xmx3076m -XX:MaxPermSize=256m"

mvn -T C2.0 clean install

Hi Ben, can you please provide the Maven command you ran and the entire output (this will be long, so posting as a GitHub Gist can be helpful)? That dependency is brought in by the Hadoop jars, but it should be available to you.
