无法解析模板“类”

我正在尝试在Android中创建类，但我得到了这个错误

无法解析模板“类”错误消息：此模板未生成 Java 类或接口

在事件日志中，我得到了这个错误

FileNotFoundException： Entry fileTemplates//code/Google Test Fixture SetUp Method.cc.ft 在 /D：/Android%20Studio/lib/idea 中找不到.jar

这是我的应用程序 bulid gradle

apply plugin: 'com.android.application'

android

这个建筑项目

// Top-level build file where you can add configuration options common to all sub-projects/modules.

  buildscript {
  repositories {
    jcenter()
  }
  dependencies {
    classpath 'com.android.tools.build:gradle:2.3.3'
    classpath 'com.google.gms:google-services:3.1.0'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    }
 }

 allprojects {
  repositories {
    jcenter()
  }
}

task clean(type: Delete) {
  delete rootProject.buildDir
}

怎么了？
