Maven原型(prototype)问题

Question

我是maven的新手。我在我的机器上安装了 apache archiva 用作 maven-proxy。我的目的是我想使用 maven archiva 插件生成一个示例项目结构。为此，我已经使用 archiva 上传了所需的 Artifact 。

当我运行 mvn archetype:generate 时，它​​应该询问我其余的参数。但相反，它给了我以下错误。这表明我有 maven 共享插件。但我还使用 archiva 上传了 maven 共享插件 Artifact 。

这是堆栈跟踪

作为help link指出，看起来您可能有一个损坏的 jar，在本例中为 maven-invoker-2.0.x.jar。您可以检查本地存储库并验证它，如果需要，将其删除并重试。

也有可能是您的文件本身有损坏的 jar，在这种情况下您需要在那里删除它。
