如何在Eclipse中的m2e / Installed maven中配置工具鏈插件

Question

目前我在我的Windows機器上安裝了maven（Apache Maven 3.3.9） 和Java（Java版本：1.8.0_91） 。 我有一個使用Java Version 1.6.0_31開發的java應用程序。

由於Apache maven（3.3.9）與之前版本的Java（1.8之前的版本）不直接兼容，因此我已經包含了工具鏈插件來編譯和運行Java 1.6項目。 我可以使用命令提示符進行成功構建。

但是當我嘗試使用eclipse與eclipse m2e插件構建相同的項目或使用eclipse-> Windows-> Preferences-> Maven-> Installations添加外部maven（3.3.9）時 ，我收到以下錯誤。

注意：使用Java_1.8，我可以在沒有工具鏈插件的情況下成功構建項目。 但是配置了工具鏈插件我面臨着這個問題。 任何人都可以幫我解決這個問題。

所需的toolchains.xml存在於maven配置文件夾以及存儲庫的.m2文件夾中

更新：Maven編譯器插件配置：

在eclipse運行配置中更改目標后解決如下。

問題是eclipse不會自動讀取toolchains.xml。 我們必須在目標中手動指定。 我通過引用此鏈接修復此問題
