maven-dependency-plugin：获取依赖项时失败

Question

我正在尝试使用maven-dependency-plugin将依赖项复制到另一个位置，但是，当从私有nexus服务器检索特定org.codehaus.plexus:plexus-container-default:pom:1.0-alpha-30的传递依赖项时，它在校验和验证时失败。

Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.8:copy-dependencies (copy-dependencies) on project myapp: Execution copy-dependencies of goal org.apache.maven.plugins:maven-dependency-plugin:2.8:copy-dependencies failed: Plugin org.apache.maven.plugins:maven-dependency-plugin:2.8 or one of its dependencies could not be resolved: Failed to collect dependencies for org.apache.maven.plugins:maven-dependency-plugin:jar:2.8 (): Failed to read artifact descriptor for org.codehaus.plexus:plexus-container-default:jar:1.0-alpha-30: Could not transfer artifact org.codehaus.plexus:plexus-container-default:pom:1.0-alpha-30 from/to mycompany.nexus (http://nexus.mycompany.com/content/groups/public): Checksum validation failed, expected aa1efeb7ed05a3c5037cc194b9e8fbf97e52268a but is 351451aebadb3a5dfa07ea8bdf9e4e336d299054

我试图强制使用plexus-container-default依赖的版本而没有运气。 如果有人能够解决我如何解决这个noob问题，我们将不胜感激

谢谢！

这是我朋友的相关片段：
