线程“main”中的异常java.lang.UnsatisfiedLinkError：java.library.path中没有ntcore？

我试图在gazebosim中运行一些基本的代码，项目建立良好，但一旦它连接到凉亭我得到的错误“线程中的异常”主“java.lang.UnsatisfiedLinkError：没有ntcore在java.library.path”线程“main”中的异常java.lang.UnsatisfiedLinkError：java.library.path中没有ntcore？

我已经找到了文件ntcore.so与-Djava'library.path

target name="simulate" depends="jar-for-simulation"> 
<sequential> 
    <echo>[simulate] You may now run Gazebo and your DriverStation</echo> 
    <echo>[simulate] Running Code.</echo> 
    <java jar="${simulation.dist.jar}" fork="true"> 
     <jvmarg value="-Djava.library.path={/home/alex/wpilib/java/current/lib/native/lib/libntcore.so}" /> 
    </java> 
</sequential>

任何想法sepcified它的位置？这是推动我控制台的疯狂

尝试设置java.library.path图书馆所在的目录，而不是库本身。

<jvmarg value="-Djava.library.path=/home/alex/wpilib/java/current/lib/native/lib" />

（林不知道，如果{}是必需的或有问题的？）

的错误的原因可以是以下;

原因：

的PATH变量不包括其中包含的Java类的功能所要求的本地库的目录。

解决方法：

在Windows或/和Unix平台上，添加您的依赖关系到PATH变量。按照this文章，详细了解

你可以在Eclipse启动配置

添加-Djava.library.path作为VM参数我不是很久以前，有这种确切的问题。我解决这个问题的方法是通过编译ntcore来源使用Gradle.

有关如何执行此操作的说明包含在ntcore的自述文件中。
