Java 无法在eclipse中创建Maven项目

嗨，我的系统中有EclipseNeo和java1.8。我已经在eclipse中添加了drools 6.5 jar，但是我无法创建maven项目

---

有人能告诉我创建maven项目的完整过程吗，或者我忘记了一些事情吗？

请确保在您的IDE中安装了

maven Integration for Eclipse

插件（默认情况下应该在

Eclipse

中安装）。 要验证这一点，请导航到窗口->首选项，并确保左侧首选项列表中列出了

Maven

。 如果未安装maven，请使用

EclipseMarketplace

安装它。

---

如果是这样，只需导航到File->new->Other->Maven->Maven project来创建一个新的Maven项目。

您也可以从命令行创建项目

mvn原型：生成

然后将其作为maven项目导入eclipse中


下面是命令输出示例
