通过wget http://repo.maven.apache.org 它没有显示任何错误。任何人都可以帮助我吗？

我正在尝试运行 YCSB 基准测试，但出现此错误。

如错误所述，您无法连接到 Maven 存储库:http://repo.maven.apache.org

尝试不同的存储库，details here或者添加到你的 pom，这个:

<repository>              
          <id>central</id>
          <name>Central</name>
          <url>http://repo1.maven.org/maven2</url>
</repository>
