部署到 nexus 时未更新 maven-metadata.xml

Question

我正在使用 Apache Maven 3.0 Nexus 开源版，版本：1.8.0.1

这是我的 pom.xml 的一部分

<plugin>
   <artifactId>maven-deploy-plugin</artifactId>
   <version>2.5</version>
</plugin>
<plugin>
   <artifactId>maven-release-plugin</artifactId>
   <version>2.1</version>
</plugin>

<distributionManagement>
   <repository>
   <id>nexus</id>
   <name>nexus</name>
   <url>http://myrepo/nexus/content/repositories/releases</url>
   </repository>
</distributionManagement>

这是一个非常简单的项目。当我这样做时

  mvn release:prepare
  mvn release:perform

一切正常：

...
[INFO] [INFO] --- maven-deploy-plugin:2.5:deploy (default-deploy) @ simple ---

现在我下载http://myrepo/nexus/content/repositories/.../maven-metadata.xml 它看起来像这样：

<metadata>
<groupId>simple</groupId>
<artifactId>simple</artifactId>
<versioning>
<latest>0.5.8</latest>
<release>0.5.8</release>
<versions>
<version>0.5.9</version>
<version>0.1</version>
<version>0.3</version>
<version>0.4</version>
<version>0.5.1</version>
<version>0.5.2</version>
<version>0.5.3</version>
<version>0.5.4</version>
<version>0.5.5</version>
<version>0.5.6</version>
<version>0.5.7</version>
<version>0.5.8</version>
</versions>
<lastUpdated>20110202190804</lastUpdated>
</versioning>
</metadata>

我的最新和刚刚发布的版本没有标记为“最新”和“发布”。

现在我在 Nexus WebUI 中执行“重建元数据”。在此之后我再次下载元数据。现在看起来是这样的

<metadata>
  <groupId>simple</groupId>
  <artifactId>simple</artifactId>
  <versioning>
    <latest>0.5.9</latest>
    <release>0.5.9</release>
    <versions>
      <version>0.1</version>
      <version>0.3</version>
      <version>0.4</version>
      <version>0.5.1</version>
      <version>0.5.2</version>
      <version>0.5.3</version>

      <version>0.5.4</version>
      <version>0.5.5</version>
      <version>0.5.6</version>
      <version>0.5.7</version>
      <version>0.5.8</version>
      <version>0.5.9</version>

    </versions>
    <lastUpdated>20110202191117</lastUpdated>
  </versioning>
</metadata>

这看起来像是 nexus 或 maven 中的错误？有人对此有解决方案吗？

Answer 1

您是否尝试在部署插件配置中将 updateReleaseInfo 设置为 true？

<plugin>
    <artifactId>maven-deploy-plugin</artifactId>
    <version>2.5</version>
    <configuration>
        <updateReleaseInfo>true</updateReleaseInfo>
    </configuration>
</plugin>

注意，我没有尝试过，只是在我阅读此问题时碰巧打开了部署插件文档，这似乎是合理的。

来自Maven docs：

updateReleaseInfo:
Parameter used to update the metadata to make the artifact as release.

Type: boolean
Required: No
Expression: ${updateReleaseInfo}
Default: false
