Maven项目未能建成

Question

我是Maven项目的新手.我将一个现有的Maven项目导入eclipse,然后进行了新的配置.我尝试运行该应用程序,但控制台显示

[ERROR] Failed to execute goal com.google.appengine:appengine-maven-plugin:1.9.4:devserver (default-cli) on project helloworld: The plugin com.google.appengine:appengine-maven-plugin:1.9.4 requires Maven version 3.1.0 -> [Help 1]

我检查了它显示的链接.它建议将构建环境更新为所需的Maven版本.我搜索了它,但发现在pom.xml中进行了一些更改.但没有任何效果.谁能告诉我如何解决这个问题.我安装的Maven版本是3.0.5.

Answer 1

有同样的问题.解决方案很简单.Eclipse的期待行家根有bin,boot,conf,和lib子文件夹.根文件夹不是(在我的情况下)/usr/local/Cellar/maven32/3.2.5,而是/usr/local/Cellar/maven32/3.2.5/libexec.请注意,正确的是一个文件夹更深.
