Question

我正在尝试创建一个在scala中编译和运行程序的pom.xml。该项目需要运行一些* .so库（例如gluegen-rt.so）。这些文件位于：/ usr / lib / jni /

运行程序时出现此错误：

Exception in thread "main" java.lang.UnsatisfiedLinkError: no gluegen-rt in java.library.path
    at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1738)
    at java.lang.Runtime.loadLibrary0(Runtime.java:823)

    at fr.iscpif.slocalfit.testGraphique$.main(testGraphique.scala:28)
    at fr.iscpif.slocalfit.testGraphique.main(testGraphique.scala)

所以我用maven对链接库进行了一些研究，我在pom.xml上找到了这个命令行：

<systemProperties>
<property>
<name>java.library.path</name>
<value>/usr/lib/jni/</value>
</property>
</systemProperties>

但是我不知道我可以在哪里写这一行到我的pom.xml中，因为我想要maven将这些行添加到java命令行之前我运行我的课程的主要课程......

祝你好运，谢谢你的帮助，

我的pom.xml实际上是这样的：

我从未与maven合作，但与JNI合作很多。

您是否在IDE中指定了本机库路径？如果您使用像NetBeans或Eclipse这样的IDE，那么在将.jar文件添加到IDE时，您必须指定Java Native Library（对于某些java .jar库）所在的位置（我的意思是.dll或.so）。

对于前。在Eclipse中：右键单击项目 - ＆gt;属性 - ＆gt; Java构建路径 - ＆gt;库（在标签栏上） - ＆gt;单击库（并展开它），您可以在那里找到本机库位置。您只需指定.so文件所在的路径。您必须在NetBeans上执行类似的过程：我认为您必须按Project Properties - ＆gt;图书馆，你找到这些东西。

希望它有用:)

使用maven和ubuntu为scala添加java.library.path到/ usr / lib / jni
