如何在m2e中配置工具链插件/在Eclipse中安装maven

Question

目前，我正在使用安装在我的windows机器上的 Maven (Apache 3.3.9) & Java(Java : 1.8.0_91)。我有一个java应用程序，它是使用Java 1.6.0_31开发的。

由于Apache (3.3.9)与以前版本的不直接兼容(在1.8之前)，所以我在Java1.6中包含了编译和运行项目的工具链插件。我可以使用命令提示符成功构建。

但是，当我试图使用带eclipse->Windows->Preferences->Maven->Installations，的eclipse m2e插件或通过使用添加外部maven(3.3.9)来构建相同的项目时，我将得到以下错误。

注释:使用和Java_1.8我可以成功地构建项目而不需要工具链插件。但是随着工具链插件的配置，我面临着这个问题。有人能帮我解决这个问题吗。

必需的toolchains.xml既存在于maven配置文件夹中，也存在于存储库的.m2文件夹中。

更新: Maven编译器插件配置：

在eclipse中更改目标后的解决方案运行配置，如下所示。

问题是eclipse并不是自动读取toolchains.xml。我们必须在目标中手动指定。我通过引用这个链接修复了这个问题
