android studio的gradle同步时报错GradleScriptException

gradle编译问题：

A problem occurred evaluating project ':login'.
> Could not find method plugins() for arguments [build_2c31lk3groc7yx58a8uwub95i$_run_closure2@cf3b05b] on project ':login' of type org.gradle.api.Project.
org.gradle.api.GradleScriptException: A problem occurred evaluating project ':login'.
Caused by: org.gradle.internal.metaobject.AbstractDynamicObject$CustomMessageMissingMethodException: Could not find method plugins() for arguments [build_2c31lk3groc7yx58a8uwub95i$_run_closure2@3f8bc2a0] on root project 'ModuleComponentDemo' of type org.gradle.api.Project.
at build_2c31lk3groc7yx58a8uwub95i.run(D:\Workspace\Project\Android\StudyStore\kt\ModuleComponentDemo\login\build.gradle:7)

引发问题的gradle文件中代码：

if (isRelease) {
    plugins {
        id 'com.android.library'
        id 'org.jetbrains.kotlin.android'
    }
} else {
    plugins {
        id 'com.android.application'
        id 'org.jetbrains.kotlin.android'
    }
}

处理方案：

if (isRelease) {
    apply plugin: 'com.android.library'
    apply plugin: 'org.jetbrains.kotlin.android'
} else {
    apply plugin: 'com.android.application'
    apply plugin: 'org.jetbrains.kotlin.android'
}
