我是新的机器人工作室，当我同步的Andr​​oid应用程序，我得到的错误。

  C：\ Users \用户Mansukh \桌面\布局\ MaterialDesignLibrary主\ MaterialDesign \ build.gradle

错误：（97，0）不能调用getBootClasspath（）setTargetInfo前（）被调用。
 

请谁能告诉我什么是错误的意思，什么是此错误的解决方案。我试图找到在互联网上的问题，但我无法得到特定的解决方案。

下面是我的 gradle.build 文件。

解决方案

这是这里所描述的摇篮1.1.0插件中的错误：的问题152811 。修复已经发布

解决方案是更改插件版本为1.1.1或更高版本（目前可用的版本是1.1.2）。 类路径com.android.tools.build:gradle:1.1.2

更新

还有一个类似的错误 Android的摇篮插件1.1.0分行符的Javadoc任务其固定在1.2.2版本。

This a bug in Gradle 1.1.0 plugin as described here: Issue 152811. Fix is already released

Solution is to change plugin version to 1.1.1 or higher (currently available version is 1.1.2). classpath 'com.android.tools.build:gradle:1.1.2'

Update

There is another similar bug Android Gradle Plugin 1.1.0 breaks Javadoc tasks which is fixed in 1.2.2 version.
