为什么我无法在IntelliJ IDEA中选择某个语言级别以上?

[英]Why am I not able to select above a certain language level in IntelliJ IDEA?

我可以在项目结构下设置的最大语言级别为9 I'm running IntelliJ with JDK 11, but it won't let me select higher than 9 for project language level. 我正在使用JDK 11运行IntelliJ,但它不会让我选择高于9的项目语言级别。 What is going on here? 这里发生了什么?

Development -- Looks like in the "About" Section under IntelliJ IDEA, my JRE is 1.8...how can I modify this? 开发 - 看起来像IntelliJ IDEA下的“关于”部分,我的JRE是1.8 ...我怎么能修改它?

JRE在这里是1.8

You need to update your Intellij Version, 2017.3.5 does not support project level higher than 9 您需要更新您的Intellij版本, 2017.3.5不支持高于9的项目级别

Update from : Download IntelliJ IDEA 更新自: 下载IntelliJ IDEA
