当我在Intellij IDEA（Ultimate）11.1中使用maven进行单元测试时。我得到了以下例外。

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，但仍然没有用。

注意：

我可以用bash中的“mvn test”通过测试。（我在〜/ .profile中添加了“export LD_LIBRARY_PATH = / usr / local / lib”）
我在pom中配置了这个而不是jzmq，因为我需要在我的项目中使用storm并且风暴引用了jzmq。

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

我尝试从终端启动Intellij，它运行正常。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。选中http://blog.bluecalyx.org/2009/07/02/missing-environment-variables-in-intellij/后，我使用 bash --login IDEAPATH / bin / idea.sh 更新了Intellij桌面文件中的exec，然后世界变得和平。

我仍然感到困惑的是，即使我在Intellij maven runner设置中添加了 -Djava.library.path = / usr / local / lib ，它也无效。

最后，只是提醒一下，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

在使用Maven在Intellij IDEA中运行单元测试时，zmq失败
