当我在Intellij IDEA(Ultimate)11.1中使用maven运行单元测试时。我得到了以下异常。

从互联网搜索后,似乎zmq缺少java.library.path - usr/local/lib。所以我尝试将"-Djava.library.path=/usr/local/lib"添加到 maven 的 vm 选项中,但仍然不好。
注意:
我可以通过 bash 中的"mvn 测试"进行测试。(我在~/.profile中添加了"export LD_LIBRARY_PATH=/usr/local/lib")
我在pom而不是jzmq中配置了它,因为我需要在项目中使用storm并且storm引用jzmq。
<dependency> <groupId>storm</groupId> <artifactId>storm</artifactId> <version>0.7.4</version> </dependency>
我尝试从终端启动 Intellij,它工作正常。当我从 Ubuntu 的启动面板启动它时,它不是从我的任何登录环境变量开始的。检查 http://blog.bluecalyx.org/2009/07/02/missing-environment-variables-in-intellij/后,我用bash更新了Intellij桌面文件中的exec--login IDEAPATH/bin/idea.sh,然后世界变得和平。
我仍然感到困惑的一件事是,即使我在 Intellij maven runner 设置中添加了 -Djava.library.path=/usr/local/lib,它也无法正常工作。
最后,提醒一下,在开始使用ZMQ和jzmq之前,有必要安装它。请参阅 www.zeromq.org/intro:get-the-software 和 www.zeromq.org/bindings:java
