maven项目上的MojoFailureException

Question

我刚刚签出这个项目https://github.com/tjeerdnet/OneDriveAPI

我的目标是运行它。

所以我添加到 eclipse Kepler 作为我的 java 项目。

然后，我将我的项目更改为一个maven项目（因为我看到有一个pom.xml）

我将它作为 Maven 构建运行，目标是“安装”

控制台显示一堆编译错误如下：

然后我运行我的服务器并从控制台获取这些错误日志：

我做错了什么？

我对 maven 和 JEE 很陌生，很抱歉这个菜鸟问题

Answer 1

我也有一些类似的东西。问题在于java版本。确保在编写应用程序的系统中安装了相同的 Java 版本（主要和次要）。
