Additional Informations

I was wondering if there was a way to make a single project run java programs using JDK 8. I have already put this specific JDK in java.configuration.runtimes but I am not seeing the status bar icon to change the Java Language Level. I have gotten it to work by setting default to true for the JDK I want to use in java.configuraiton.runtimes but I was wondering if there was a way to do this that didn't involve changing my settings for all projects.

首先检查 issue 中描述的 java.configuration.runtimes 的按项目行为以及 Java Language Level 状态栏控件。确认 Visual Studio Code 1.47.3 搭配 Java extension 0.65.0 是否支持针对项目选择 JDK 8；完成标准是记录受支持的设置或确定缺失的功能。
