今天从Eclipse切换Android Studio工程时，报了个奇葩错误：
Error:(1,0) Plugin is too old, please updatetoamore recentversion,orsetANDROID_DAILY_OVERRIDE environment variab

找了半天也没找到什么原因，把原来的好的工程拿出来看了看，替换了Project下的build.gradle文件，就好了，然后比较新旧两个文件，原来是这里不一样：
旧文件（可以运行的）
// Top-level build file where you can add configuration options common to allsub-projects/modules.buildscript {repositories { jcenter() } dependencies { classpath'com.android.tools.build:gradle:1.2.3'// NOTE: Donotplace your application dependencies here; they belong // in the individual module build.gradle files }}allprojects { repositories { jcenter() }}
新文件（不可以运行的：）
// Top-level build file where you can add configuration options common to allsub-projects/modules.buildscript {repositories { jcenter() } dependencies { classpath'com.android.tools.build:gradle:2.0.0-alpha1'}}allprojects { repositories { jcenter() }}
原来是classpath升级了，导致的问题！换回原来的就好了
