Question

当我通过“run as”==＆gt;运行我的maven项目时在我的eclipse IDE中“Maven build”，img中显示的错误发生了。！[在此输入图像说明] [1]

我的JDK版本是：1.7.0_76 Maven版本是：3.3.1 echo％JAVA_hOME％= D：\ work \ Java \ jdk1.7.0_76 echo％M2_HOME％= D：\ work \ apache-maven-3.3.3 在我的eclipse IDE我的maven设置就像在img下面一样：[在这里输入图像描述] [2]！[在此输入图像描述] [3]

我的项目的构建路径是！[在此输入图像描述] [4]

这是因为这个项目是用JDK1.6编译的旧项目，所以，我选择安装的jdk1.6。但是当作为maven构建运行时，错误就像图1一样！

帮助我，请！

如果您选择运行方式→ Maven构建，则使用Eclipse 运行配置（请参阅菜单运行→ 运行配置... ）。如果是 Maven Build ，则必须在其目标：字段中指定至少一个适当的目标（例如Maven's built-in lifecycles之一）。

尝试执行“mvn build”命令时，Maven出错
