IntelliJ IDEA Community Edition 2018.3 的 build.gradle 异常

Question

在我将 IntelliJ Idea Community Edition 从版本 2018.2 更新到版本 2018.3 后，我的项目不再工作。问题出在 build.gradle 中，因为它向我表明，例如：无法解析符号 'buildscricpt'。这适用于 build.gradle 中的每个符号。

这是我的 build.gradle：

buildscript
{
    repositories
    {
        maven
        {
            url 'https://plugins.gradle.org/m2/'
        }
    }
    dependencies
    {
        classpath 'com.google.gradle:osdetector-gradle-plugin:1.6.0'
    }
}
plugins
{
    id 'application'
    id 'java'
}
group 'de.uniks'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

mainClassName = 'de.uniks.MainApp'

apply plugin: 'com.google.osdetector'

repositories
{
    mavenCentral()
    maven
    {
        url 'https://oss.sonatype.org/content/repositories/snapshots'
    }
}

ext.platform = osdetector.os != 'osx' ? osdetector.os : 'mac'

dependencies
{
    testCompile group: 'junit', name: 'junit', version: '4.12'
    testCompile 'org.fulib:fulib:1.0.+'

    implementation "org.openjfx:javafx-base:11:${platform}"
    implementation "org.openjfx:javafx-graphics:11:${platform}"
    implementation "org.openjfx:javafx-controls:11:${platform}"
    implementation "org.openjfx:javafx-fxml:11:${platform}"
    implementation 'javax.annotation:javax.annotation-api:1.3.2'
}

这是错误信息：

尝试关闭 IDE，然后删除或重命名位于 C:/Users//.gradle 中的 .gradle 文件夹并重新启动 IDE。
