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

Question

目前我正在使用 ma​​ven(Apache Maven 3.3.9) & Java(Java version: 1.8.0_91) 安装在我的 windows 机器上。我有一个使用 Java 版本 1.6.0_31 开发的 java 应用程序。

因为 Apache maven(3.3.9) 不直接兼容以前的 Java 版本(1.8 之前)，所以我包含了 toolchains plugin 使用 Java 1.6 编译和运行项目。我可以使用命令提示符成功构建。

但是，当我尝试使用带有 eclipse m2e 插件 的 eclipse 构建相同的项目时，或者使用 eclipse-> 添加external maven(3.3.9) 时Windows->Preferences->Maven->Installations，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后，我面临着这个问题。谁能帮我解决这个问题。

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:

Answer 1

在 eclipse 运行配置中更改目标后解决，如下所示。

问题是 eclipse 没有自动读取 toolchains.xml。我们必须在目标中手动指定。我通过引用 this Link 解决了这个问题
