java - 每次我重新导入 gradle 时，IntelliJ 都会重置我的 Java 设置

Question

我发现了几个涉及 mvn 的类似报告，但没有一个与 Gradle 相关的报告。问题就在这里。

我转到"file"->“项目结构”->“项目”，并将“项目 SDK”更改为 11，将“项目语言级别”更改为 10。单击“应用”，错误消失。

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 上发现的问题后，这是我的 build.gradle。

// Define the main class for the application

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

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

刷新。它仍然重置我的项目设置。

这是渐变设置:

请帮忙。

有时会发生这种情况。项目文件可能会变得相当复杂，尤其是当您正在处理多模块文件时。

首先，我更喜欢始终使用 Enum 常量。

sourceCompatibility = JavaVersion.VERSION_11
targetCompatibility = JavaVersion.VERSION_11

然后，备份.idea/modules.xml，将其删除并从Gradle工具窗口重新导入Gradle项目。

<小时/>

最后一步，备份项目 *.iml 文件，将其删除，然后按上述方式重新导入。
如果未重新创建 *.iml 文件，请重新启动 idea。

让我知道这是否有效。
