如何在Eclipse中的m2e/Installed maven中配置工具链插件

Question

目前我在我的Windows机器上安装了maven(Apache Maven 3.3.9) 和Java(Java版本:1.8.0_91).我有一个使用Java Version 1.6.0_31开发的java应用程序.

由于Apache maven(3.3.9)与之前版本的Java(1.8之前的版本)不直接兼容,因此我已经包含了工具链插件来编译和运行Java 1.6项目.我可以使用命令提示符进行成功的构建.

但是当我尝试使用eclipse与eclipse m2e插件构建相同的项目或使用eclipse-> Windows-> Preferences-> Maven-> Installations添加外部maven(3.3.9)时,我收到以下错误.

注意: 使用Java_1.8,我可以在没有工具链插件的情况下成功构建项目.但是配置了工具链插件我面临着这个问题.任何人都可以帮我解决这个问题.

所需的toolchains.xml存在于maven配置文件夹以及存储库的.m2文件夹中

更新:Maven编译器插件配置:

在eclipse运行配置中更改目标后解决如下.

问题是eclipse不会自动读取toolchains.xml.我们必须在目标中手动指定.我通过引用此链接修复此问题
