此环境中未提供任何编译器。也许您正在JRE而不是JDK上运行？

eclipse java maven java-7 m2eclipse

我正在使用m2eclipse在Eclipse中编译一个项目。我在 Eclipse 中设置了 JDK 路径，如下所示：

Windows-->preferences-->installed jres--> jdk1.7.xx  path

但这显示错误

答案 1

在 Eclipse IDE 上，> Java >已安装的 JREs >进入“窗口>首选项”，然后检查已安装的 JRE。你应该有一个带有JDK的条目。
选择执行环境，如下所示。单击“确定”
然后右键单击您的项目 - > Maven - >更新项目
