java - 有了m2e还需要安装Maven吗？

Question

我已经通过 Eclipse 市场在我的 Eclipse Indigo 中安装了 m2e。

我是否需要显式安装 maven 并设置 M2_HOME 环境变量？

谢谢!

Answer 1

没有也没有。 m2e 有一个嵌入式 Maven，但您不必使用它。

参见 FAQs关于更多细节，它被称为Maven Embedder:

What Maven version is used by plugin

Plugin is not actually using Maven itself. It is using component that is part of Maven called Maven Embedder. This component is not available for Maven 2.0.x. The Embedder is used by the Maven command line interface (CLI) starting from version 2.1 that includes number of improvements to allow it to actually embed Maven.

The m2eclipse is currently using the Embedder component from Maven 3.0. If you want to execute particular version of Maven installed elsewhere, you can do so from the Maven launch configuration or select it as default in Maven / Installations preference page.
