如何使 Maven 部署插件只上传特定文件？

Question

我想在 Nexus 中 add two zips to an already published version。
从本质上讲，它们是应用程序的压缩演示和同一应用程序的扩展版本，也是压缩的。

使用 Deploy 插件，我在我的 pom 中定义了两个执行，每个文件一个，并将它们绑定到部署阶段。这是演示：

<execution>
   <id>deploy-essential</id>
      <phase>deploy</phase>
      <goals>
         <goal>deploy-file</goal>
      </goals>
      <configuration>
         <file>${project.build.directory}/${project.artifactId}-${project.version}-demo.zip</file>
         <groupId>${project.groupId}</groupId>
         <artifactId>myproject</artifactId>
         <version>${project.version}</version>
         <classifier>demo</classifier>
         <repositoryId>nexus</repositoryId>
         <url>${targetrepository}</url>
         <generatePom>false</generatePom>
      </configuration>
   </execution>

我希望 Maven 在执行此操作时上传文件并将元数据更新到给定的 G/A/V 坐标。 但是，它会将给定文件和包含完整版本的姊妹文件上传到给定坐标，然后将它们再次上传到原始坐标。

然后它继续为第二次执行再次执行所有这些操作。以下是我的日志摘录：

这对 SNAPSHOT 来说不是什么大事，但它会完全阻止发布，因为 Nexus 被配置为拒绝重新部署。

我不认为这种行为是有意的，而且我确信我遗漏了一些东西。 我可以让 Maven 只上传我实际配置的文件吗？

Answer 1

因为您没有禁用默认部署机制，所以它仍在执行中。你需要这样的东西：

        <plugin>
            <artifactId>maven-deploy-plugin</artifactId>
            <executions>
                <!-- disable standard deploy -->
                <execution>
                    <id>default-deploy</id>
                    <phase>none</phase>
                </execution>
                <execution>
                    <id>deployEssential</id>
                    <phase>deploy</phase>
                    ...
                </execution>
            </executions>
        </plugin>

Answer 2

使用内置部署插件（用于部署 maven 工件）的替代方法：

• 禁用内置部署机制
• 为部署阶段启用wagon-maven-plugin
• 将 FTP 凭据添加到 HOME/.m2/settings.xml
• 执行mvn deploy复制FTP文件

---

<!-- disable standard deploy -->
<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-deploy-plugin</artifactId>
  <version>3.0.0-M1</version>
  <executions>
    <execution>
      <id>default-deploy</id>
      <phase>none</phase>
    </execution>
  </executions>
</plugin>
<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>wagon-maven-plugin</artifactId>
  <version>1.0</version>
  <executions>
    <execution>
      <id>deploy-release</id>
      <phase>deploy</phase>
      <goals>
        <goal>upload</goal>
      </goals>
      <configuration>
        <serverId>nexus</serverId>
        <url>${targetrepository}</url>
        <fromDir>${project.build.directory}</fromDir>
        <toDir>${project.version}</toDir>
        <includes>${project.artifactId}-${project.version}-demo.zip</includes>
      </configuration>
    </execution>
  </executions>
</plugin>

为什么不使用可以将工件附加到当前部署的程序集插件，或者使用可以简单地将其他工件附加到您的构建的 build-helper-maven-plugin。在通常的构建过程中使用部署插件是错误的方式。
