这是对以下内容的跟进： Followup questions: Using Maven to only sign and deploy jars to Maven Central. Build and compilation is done entirely with Ant

感谢对前面问题的回答，以及 sonatype 支持人员的一些建议，我刚刚有了我的第一个“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

在浏览器中实际查看该目录时，我会看到以下文件：

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说发送了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（连同他们的 *.asc 同伴），但他们都不是。

在 POM 中，我有这个属性

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

还有这个 plugins 块（它是 profiles 部分的子集），其中包含三个工件，每个工件都明确指向这三个 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

罐子在里面

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

)

那么让 POM 的下一步是什么

识别 jar 文件
签名（并提示我输入我的公钥密码，对吗？），然后
将它们推送到 Maven？

以下是我更新的settings.xml 和pom.xml。

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

谢谢你帮助我。

【问题讨论】：

1.对于“20140717”问题，您与服务器处于同一时区吗？ 2. 有没有用另一台电脑试试看能否下载依赖？
@coolcfan 还没有准备好回答这个问题，因为我还没有上传我期望的文件（无论日期/时间如何）......
@coolcfan 实际上，他们现在似乎在那里：oss.sonatype.org/content/repositories/snapshots/com/github/…

标签： java maven ant

【解决方案1】：

您正在将工件附加到 release-sign-artifacts 配置文件中，当您运行“mvn deploy”命令时，该配置文件可能已禁用。尝试运行 mvn deploy -Drelease=true 或将 release-sign-artifacts 配置文件移动到主要的 .pom 部分。完全不确定您是否需要单独的个人资料。

时间戳很好。这就是 Maven 存储库存储 SNAPSHOT 的方式。

Maven 有一个陡峭的学习曲线，但是一旦你理解了基本概念，它就会起作用。

【讨论】：

就是这样。出色的。我即将写一个总结我所做的答案。现在进入下一个问题......

【解决方案2】：

这是我所做的更改，正如@AlexeyGavrilov's answer 中所建议的那样：
