在Maven中使用本地依赖关系 [英] Using native dependencies inside Maven

问题描述

POM依赖项包含本机库（JAR文件内的DLL）。如何以编程方式查找下载的JAR文件的路径，以便我可以将其传递给java.library.path？

解决方案

简而言之，你可以使用maven -dependency-plugin：解压缩目标，将库解压缩到已知路径中，并将其传递到 java.library.path 中：

 < plugin> 
< groupId> org.apache.maven.plugins< / groupId> 
< artifactId> maven-dependency-plugin< / artifactId> 
<执行> 
< execution> 
< id> unpack< / id> 
< phase> compile< / phase> 
< goals> 
< goal> unpack< / goal> 
< / goals> 
< configuration> 
< artifactItems> 
< artifactItem> 
< groupId> org.jdesktop< / groupId> 
< artifactId> jdic-native< / artifactId> 
< version> $ {jdic.version}< / version> 
< classifier> $ {build.type}< / classifier> 
< type> jar< / type> 
< overWrite> true< / overWrite> 
< outputDirectory> $ {project.build.directory} / lib< / outputDirectory> 
< / artifactItem> 
< / artifactItems> 
< / configuration> 
< / execution> 
< / executions> 
< / plugin> 
  

A POM dependency contains native libraries (DLLs inside a JAR file). How do I programmatically look up the path of the downloaded JAR file so I can pass it into "java.library.path"?

In short, you can use the maven-dependency-plugin:unpack goal to extract the libraries into a known path, and pass that into java.library.path:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-dependency-plugin</artifactId>
  <executions>
    <execution>
      <id>unpack</id>
      <phase>compile</phase>
      <goals>
        <goal>unpack</goal>
      </goals>
      <configuration>
        <artifactItems>
          <artifactItem>
            <groupId>org.jdesktop</groupId>
            <artifactId>jdic-native</artifactId>
            <version>${jdic.version}</version>
            <classifier>${build.type}</classifier>
            <type>jar</type>
            <overWrite>true</overWrite>
            <outputDirectory>${project.build.directory}/lib</outputDirectory>
          </artifactItem>
        </artifactItems>
      </configuration>
    </execution>
  </executions>
</plugin>
