When I run unit test with maven in Intellij IDEA (Ultimate) 11.1. I got following exception.

After search from internet, it seems zmq missing java.library.path - usr/local/lib. So I tried add "-Djava.library.path=/usr/local/lib" to vm option of maven, but still no good.

Note:

  1. I can pass the test with "mvn test" in bash. (I added "export LD_LIBRARY_PATH=/usr/local/lib" into ~/.profile)

  2. I configured this in pom instead of jzmq, as I need to use storm in my project and storm referenced jzmq.

<dependency>
    <groupId>storm</groupId>
    <artifactId>storm</artifactId>
    <version>0.7.4</version>
</dependency>

Soluzione

I try starting Intellij from terminal, it just works fine. When I start it from launch panel of Ubuntu, it isn’t starting with any of my login environment variables. After checked http://blog.bluecalyx.org/2009/07/02/missing-environment-variables-in-intellij/ , I updated exec in the Intellij desktop file with bash --login IDEAPATH/bin/idea.sh, then the world become peaceful.

One thing I'm still confused on is, before even if I added -Djava.library.path=/usr/local/lib in Intellij maven runner setting, it doesn't work.

Last, just a reminder, before start using ZMQ and jzmq, it is necessary to install it. Refer to www.zeromq.org/intro:get-the-software and www.zeromq.org/bindings:java
