使用Maven-单目标在Jar中打包Dll

Question

我在maven项目中添加了一个DLL作为依赖项，如下所示：

<dependency>
  <groupId>com.test.dll</groupId>
  <artifactId>myDll</artifactId>
  <version>0.1</version>
  <type>dll</type>
</dependency>

当我尝试执行maven:install时

它给了我这个错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.2-   
beta-5:single (jar-with-dependencies) on project testApp: Failed to create 
assembly:    Error adding file-set for 'com.test.dll:myDll:dll:0.1' to archive: Error 
 adding archived file-set. PlexusIoResourceCollection not found for: C:\Users\USER\.m2
 \repository\com\test\dll\myDll\0.1\myDll-0.1.dll: No such archiver: 'dll'

我在这里做错什么了？

Answer 1

这里的问题是jar-with-dependencies描述符。描述符解包将所有依赖项打包到一个目录中，并将该目录打包到一个新的JAR文件中。但是，它不能解压缩DLL文件(这是“没有这样的存档”错误消息)。要使此工作正常，您需要定义自己的程序集描述符：

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">

  <id>assembly-with-dll</id>
  <formats>
    <format>jar</format>
  </formats>
  <includeBaseDirectory>false</includeBaseDirectory>
  <dependencySets>
    <!-- package the regular dependencies -->
    <dependencySet>
      <outputDirectory>/</outputDirectory>
      <useProjectArtifact>true</useProjectArtifact>
      <unpack>true</unpack>
      <scope>runtime</scope>
      <!-- exclude the DLL -->
      <excludes>
        <exclude>com.example:my-dll</exclude>
      </excludes>
    </dependencySet>
    <!-- package the DLLs -->
    <dependencySet>
      <outputDirectory>/</outputDirectory>
      <includes>
        <include>com.example:my-dll</include>
      </includes>
    </dependencySet>
  </dependencySets>
</assembly>

如果上面的描述符位于src/main/assembly中，那么maven程序集插件的配置如下所示：

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-assembly-plugin</artifactId>
      <executions>
        <execution>
          <id>jar-with-dependencies</id>
          <phase>prepare-package</phase>
          <goals>
            <goal>single</goal>
          </goals>
          <configuration>
            <descriptor>src/main/assembly/assembly.xml</descriptor>
            <appendAssemblyId>false</appendAssemblyId>
          </configuration>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

Answer 2

这里有一条信息：Maven Dll依赖问题。若要解决此问题，请从程序集中导出dll：

<excludes>
    <exclude>*:dll*</exclude>
</excludes>

上一次我必须创建一个带有依赖项的可执行jar时，我将它们放到了lib目录中的jar之外。DLL必须是：

• 无论是在应用程序类路径中(就像服务器/lib中的服务器)
• 或者在OS类路径中(例如C：\Windows\system32 32)

在阅读了您的pom和信任文件集之后，我可能能够更准确地:)

为了补充Stefan的答案，我不认为您想为您的这个项目做一个jar-with-dependencies打包。您应该考虑使用一个箱子包(比如.zip或tar.gz)。
