eclipse - 从 Eclipse 构建触发 Maven 构建

Question

我有一个基于 Maven 的 Spring MVC 项目。当我右键单击任何项​​目并单击“构建项目”时，我希望能够触发 Maven 构建。到目前为止，什么也没有发生。但是，如果我右键单击一个项目并单击 Run As...>Maven Build 并提供目标“包”，它会触发 Maven 构建。

当我单击构建项目时，是什么阻止了它运行 Maven 构建。

Answer 1

这只是意味着 Maven 不知道你想要它做什么。在不指定目标的情况下运行 maven 构建，就像mvn从命令行运行一样。这会给你一个错误。
