java - 后续第 2 部分——使用 Maven 仅对 jar 进行签名并将其部署到 Maven Central。构建和编译完全由 Ant 完成

Question

这是跟进: Followup questions: Using Maven to only sign and deploy jars to Maven Central. Build and compilation is done entirely with Ant

多亏了对前面问题的回答，以及来自 sonatype 支持人员的一些建议，我才有了我的第一个“非失败”。这是 mvn deploy 的当前输出:

根据这个日志，以下文件被上传到

https://oss.sonatype.org/content/repositories/snapshots/com/github/aliteralmind/xbnjava

• maven-metadata.xml
• 0.1.2-SNAPSHOT/maven-metadata.xml
• 0.1.2-SNAPSHOT/xbnjava-0.1.2-20140717.010135-5.pom

在我的浏览器中实际查看该目录时，我看到了这些文件:

• maven-metadata.xml(所有文件也有 md5 和 sha1 版本)
• 0.1.2-SNAPSHOT/maven-metadata.xml
• 0.1.2-SNAPSHOT/xbnjava-0.1.2-20140716.174151-1.pom

所以，我不明白为什么日志显示发送了 20140717 文件，但服务器实际上包含 20140716 版本。但是还有一个更大的问题，因为我们的目标是拥有

• xbnjava-0.1.2.jar
• xbnjava-0.1.2-sources.jar
• xbnjava-0.1.2-javadoc.jar

在服务器上(连同它们的 *.asc 伙伴)但它们都不是。

在POM中，我有这个属性

<properties>
   <jarprefix>../build/${project.artifactId}-${project.version}/download/${project.artifactId}-${project.version}</jarprefix>
</properties>

和这个 plugins block (它是 profiles 部分的子集)，它包含三个 Artifact ，每个都明确指向这三个 jar 文件之一

<plugins>
   <plugin>
      <groupId>org.codehaus.mojo</groupId>
      <artifactId>build-helper-maven-plugin</artifactId>
      <version>1.8</version>
      <executions>
         <execution>
            <id>attach-artifacts</id>
            <phase>package</phase>
            <goals>
               <goal>attach-artifact</goal>
            </goals>
            <configuration>
               <artifacts>
                  <artifact>
                     <file>${jarprefix}.jar</file>
                     <type>jar</type>
                  </artifact>
                  <artifact>
                     <file>${jarprefix}-javadoc.jar</file>
                     <type>jar</type>
                     <classifier>javadoc</classifier>
                  </artifact>
                  <artifact>
                     <file>${jarprefix}-sources.jar</file>
                     <type>jar</type>
                     <classifier>sources</classifier>
                  </artifact>
               </artifacts>
            </configuration>
         </execution>
      </executions>
   </plugin>
</plugins>

(POM是

R:\jeffy\programming\sandbox\xbnjava\pom.xml

jar 在里面

R:\jeffy\programming\build\xbnjava-0.1.1\download

)

那么下一步要让POM变成

1. 识别jar文件
2. 签名(并提示我输入公钥密码，对吗？)，以及
3. 将它们推送给 Maven？

下面是我更新的 settings.xml 和 pom.xml。

(sonatype 支持人员还建议考虑一个 "minimal Maven" idea ，它完全避免了 POM。这是一个有趣的想法，但我想先看看它。)

谢谢你帮助我。

Answer 1

您正在将 Artifact 附加到 release-sign-artifacts 配置文件中，该配置文件在您运行“mvn deploy”命令时可能已被禁用。尝试运行 mvn deploy -Drelease=true 或将 release-sign-artifacts 配置文件移动到主 .pom 部分。完全不确定您是否需要单独的配置文件。

时间戳没问题。这就是 Maven 存储库存储 SNAPSHOT 的方式。

Maven 的学习曲线很陡峭，但一旦您理解了基本概念，它就可以正常工作。
