Error:Unable to load class 'org.codehaus.groovy.runtime.typehandling.ShortTypeHandling'.

Possible causes for this unexpected error include:<ul><li>Gradle's depende

ncy cache may be corrupt (this sometimes occurs after a network connection timeout.)

<a href="syncProject">Re-download dependencies and sync project (requires network)</a></li><li>The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.

<a href="stopGradleDaemons">Stop Gradle build processes (requires restart)</a></li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

这个  我从网上 看了 需要修改2个文件 。。1：项目根目录的build.gradle .中的classpath 'com.android.tools.build:gradle:1.2.2'

2：

找到gradle-wrapper.properties文件，其中distributionUrl改成：

distributionUrl=http\://services.gradle.org/distributions/gradle-2.2.1-all.zip

我试了以后 ，还是 报同样的错 ，求老师解答 ？？？？？？
