Maven 错误 - 每次都下载依赖项

Question

每当我构建我的应用程序时，Maven 都会尝试下载一些依赖项。我可以在控制台上看到它（如下所示）。我还看到一些消息，开头是“

....no dependency information available

我不明白为什么会发生这种情况”。而且不是一次，每当我执行： $mvn test 时都会发生这种情况，

这需要很多时间，而且我正在寻找方法来抑制这种情况。

Answer 1

以离线模式执行 Maven，以避免每次运行构建时下载依赖项。

如果您使用命令行，则可以使用 -o 作为参数。

Answer 2

maven 这样做是因为它的本地存储库中没有这些 pom 文件。每次运行时它都会尝试获取它。 @bhagyas 建议了一种解决方法，但您可能想重新看看这些依赖项是如何在没有 pom 的情况下下载的
