Java IntelliJ IDEA社区版2018.3 build.gradle出现异常

在我将IntelliJ Idea社区版从2018.2版更新到2018.3版后，我的项目不再工作。问题位于build.gradle，因为它向我指示，例如：无法解析符号'buildscricpt'。这适用于build.gradle中的每个符号

这是我的身材。格雷德尔：

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'
}

这是错误消息：

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

是否使用gradle 5版本？可能是
