问题描述

我正在使用LWJGL和Maven创建一个程序，并且正在为图形代码编写单元测试.我的问题是让Maven将本机二进制文件放在班级路径上，以便测试可以进行测试.我无法克服错误:

java.lang.UnsatisfiedLinkError: no lwjgl in java.library.path

我已经得到了二进制文件，可以将目标/libs/本机/拆开，但是测试不会吸收它们.

这是我的pom:

我已经尝试过 maven-在执行测试时，请添加目录，但这似乎是在谈论资源，而不是JNI库(而且它不起作用).

和 for Maven for Maven 是相反的问题:指定已经在classpath.

推荐答案

根据 http:http:http:http:http:http://maven.40175.n5.n.nabble.com/trouble-with-java-native-libraries-td114063.html ，

SureFire插件启动VM，然后在将控件传递到JUNIT测试类之前对系统属性进行修改.对于VM来说，这为时已晚，该VM需要在VM初始化时设置Java.Library.Path.

因此，我们需要为启动时提供确定火的路径.以下工作有效:

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <forkMode>once</forkMode>
                <argLine>-Djava.library.path=${project.build.directory}/libs/natives/win32:${project.build.directory}/libs/natives/linux:${project.build.directory}/libs/natives/macosx:${project.build.directory}/libs/natives/solaris</argLine>
            </configuration>
        </plugin>

其他推荐答案

确实确定弹性配置包括设置Java库路径

例如:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
      <systemProperties>
        <property>
          <name>java.library.path</name>
          <value>target/lib/natives/</value>
        </property>
      </systemProperties>
    </configuration>
  </plugin>
