每次我重新导入gradle时，IntelliJ都会重置我的Java设置

我发现了几个类似的报告涉及mvn，但没有一个涉及Gradle。问题就在这里

我进入文件->项目结构->项目，将项目SDK更改为11，将项目语言级别更改为10。我点击应用，错误就会消失

我刷新Gradle项目，检查文件->项目结构->项目，它的项目SDK设置为8，项目语言级别设置为6

因此，在阅读了我在stackoverflow上发现的问题之后，这是我的build.gradle

}

// Define the main class for the application
mainClassName = 'manage.App'

apply plugin: 'io.spring.dependency-management'

task deploy(dependsOn: 'build', type: Copy) {
    from bootJar.archivePath
    into "/opt/heavyweight"
}

刷新。它仍然会重置我的项目设置

以下是gradle设置：

请帮忙

这种情况有时会发生。项目文件可能会变得相当复杂，尤其是在处理多模块文件时

首先，我更喜欢使用

Enum

常量

sourceCompatibility = JavaVersion.VERSION_11
targetCompatibility = JavaVersion.VERSION_11

然后，备份

.idea/modules.xml

，删除它并从Gradle工具窗口重新导入Gradle项目

---

最后一步，备份项目

*.iml

文件，删除它，然后如上所述重新导入。
如果没有重新创建

*.iml

文件，请重新启动idea

---

让我知道这是否有效。

首先使缓存无效并重新启动。没有变化。听从你的指示。没有变化（甚至没有删除所有的IML文件？@Thom你能发布你的Gradle构建文件吗？（或文件，如果是多模块的话）不，删除IML文件没有任何效果。我把整个build.Gradle放在我的问题中。@Thom检查一下你分配给Gradle的JDK版本，在构建工具下。
