运行 Sonatype Nexus 插件出现 NoClassDefFoundError 异常

Question

我正在尝试运行部署以将 Maven 插件推送到 Nexus 存储库，但出于某种原因，我不断遇到一个相当奇怪的异常：Maven 抱怨 org.apache.http.util.Args 不见了。这特别奇怪，因为插件本身似乎并不直接依赖于 org.apache.http 包，即使它传递地依赖（更有可能），相关包也存在于我的存储库中。

我没有为插件使用任何特殊配置，只是 guide 中的最低限度。 Maven 给出的完整堆栈跟踪：

我的插件配置 pom.xml:

<plugin>
  <groupId>org.sonatype.plugins</groupId>
  <artifactId>nexus-staging-maven-plugin</artifactId>
  <version>1.6.8</version>
  <extensions>true</extensions>
  <configuration>
    <serverId>ossrh</serverId>
    <nexusUrl>https://oss.sonatype.org/</nexusUrl>
    <autoReleaseAfterClose>false</autoReleaseAfterClose>
  </configuration>
</plugin>

提前感谢您的任何建议！

如果其他人遇到问题，很可能是因为项目没有使用 Apache HTTP，您可以通过编辑 POM 将依赖项直接注入插件：

<plugin>
    <groupId>org.sonatype.plugins</groupId>
    <artifactId>nexus-staging-maven-plugin</artifactId>
    <version>1.6.8</version>
    <extensions>true</extensions>
    <configuration>
        <serverId>ossrh</serverId>
        <nexusUrl>https://oss.sonatype.org/</nexusUrl>
        <autoReleaseAfterClose>false</autoReleaseAfterClose>
    </configuration>
    <dependencies>
        <!-- https://mvnrepository.com/artifact/org.apache.httpcomponents/httpcore -->
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpcore</artifactId>
            <version>4.4.6</version>
        </dependency>
    </dependencies>
</plugin>

注意用于直接注入 HTTP 核心的特定于插件的依赖项解析。
