maven-surefire-plugin,DLLs和java.library.path

Question

我有一个Maven依赖项,需要在运行时使用DLL.我想要做的是简单地在resources/lib文件夹中包含该DLL 并将其DLL放在target目录中.所以我做的是:

1. 添加了DLL src/main/resources/lib

2. 修改pom.xml为使用参数-Djava.library.path = $ {basedir}/lib,如下所示:

   <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-surefire-plugin</artifactId>
       <configuration>
           <forkMode>once</forkMode>
           <workingDirectory>target</workingDirectory>
           <argLine>-Djava.library.path=${basedir}/lib</argLine>
       </configuration>
   </plugin>
   

但是我仍然遇到java.library.path中不存在DLL的运行时错误.

Answer 1

你的<argLine/>指向错误的路径.试试这个:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
        <forkMode>once</forkMode>
        <workingDirectory>target</workingDirectory>
        <argLine>-Djava.library.path=${basedir}/src/main/resources/lib</argLine>
    </configuration>
</plugin>

如果这个DLL只用于测试,你应该把它放在src/test/resources.在这种情况下,<argLine/>路径将变为${project.build.directory}/test-classes.
