Question

I downloaded New Relic 2.12.0 and configured it according to the Heroku java configuration documentation.

I unzipped the package contents to the root of my spring mvc application directory as indicated in the following image

Next, I pushed the new files to Heroku:

$ git add newrelic
$ git commit -m 'add newrelic'
$ git push heroku master

Finally, I bootstrapped the new relic agent:

$ heroku config:add JAVA_OPTS='-Xmx384m -Xss512k -XX:+UseCompressedOops -javaagent:newrelic/newrelic.jar'

Afterwards, my application failed with the following error and appears to not be able to locate the newrelic.jar file.

The new relic documentation says the JVM args (e.g. -javaagent:newrelic/newrelic.jar) should include the full path to the newrelic.jar file, but according the the Heroku documentation, -javaagent:newrelic/newrelic.jar is all that’s needed.

UPDATE

After checking the newrelic directory on my web dyno, I noticed the jar file was missing. Now I am looking into the cause of the missing jar file.

Update

The .gitignore file in the root of my application directory excludes jar files which prevents the newrelic.jar file from being deployed.

Is it possible you’ve left something in your .gitignore file that ignores jars? If you heroku run bash and then ls newrelic do you see the jars in there?
