下面英文就是對compile和classpath區(qū)別的解釋：
I’m going to guess that you’re referencing compile and classpath
within the dependencies {} block. If that is so, those are dependency
Configurations.
A configuration is simply a named set of dependencies. The compile
configuration is created by the Java plugin. The classpath
configuration is commonly seen in the buildSrc {} block where one
needs to declare dependencies for the build.gradle, itself (for
plugins, perhaps).
classpath的作用：
buildscript itself needs something to run, use classpath
complie的作用：
your project needs something to run, use compile
所以在Project中的gradle的dependencies 指添加依賴是使用classpath的盼樟，classpath 一般是添加buildscript本身需要運行的東西晨缴。比如build.gradle中需要用到TaskName為t1的Task击碗，而這個Task定義在其他插件里面们拙，就要通過classpath添加該插件。（例子詳見（4）創(chuàng)建Task的多種方法）
定義classpath械拍，gradle會從“repositories”中下載對應(yīng)版本的Gradle。如果使用gradle wrapper的話甲馋，感覺這個配置會被忽略迄损。Wrapper會自己去下載所使用的gradle版本。
gradle wrapper task利用gradle-wrapper.properties來下載指定的gradle芹敌。
