Re: How to build? jar is not created.

[James Waldrop]

You are probably hitting the NullPointerException in one of the tests that uses Finagle. This is something the Finagle team is still tracking down, the source is a reference counted timer that underlies all the other timers that Finagle uses, and it's being referenced after it's freed for some reason. The short answer is that there's a work around:

mvn -DskipTests package

If you're hitting some other test failure, please let me know. This NullPointerException is tricky -- it only happens on some systems, and doesn't happen in CI (not our internal CI or Travis CI run against the Github repo) so I haven't bothered disabling it.

I don't know scala...

Please,Give me some advice.

[Trisha Quan]

This is actually something we should clarify better.

With maven, the way the files are generated, you actually want to take the generated zip and unpack it into a temp dir and run from there.. the jar isn't runnable alone (without its dependencies) straight from the target dir.

If it helps, here's the command for your terminal:

mkdir tmp; mv *zip; cd tmp; unzip *zip

then run the command again =)

Thank you!! :)

This is first time for me using maven. Thank you for your kind answer.

I unzip the zip file and run iago. there was any actions.

no console print, no log...

just done the process like this

xogml@ubuntu11:~/develop/iago/target/tmp$ sudo java -jar ./iago-0.5.1-SNAPSHOT.jar ./config/test-feeder.scala 

xogml@ubuntu11:~/develop/iago/target/tmp$ 

Is there anything else to run iago??

[James Waldrop]

You missed a -f before your config file. There is a bug fix for the fact that we don't print an error that we need to integrate.

Can someone please help in here?

LocalCluster is used for testing the Iago interface to zookeeper. It is defined in the testing portion of Iago and would not be part of the jar.

Yeah, using test-thrift.scala is probably the answer. This is there to support integration tests, not to actually be used "in production."
