因为本地的AndroidStudio很久没用了，所以想要研究下github上的某个代码的时候，还得重新配下环境
打开了几个项目，都是提示如下错误
Error:Unable to find method 'org.gradle.api.internal.project.ProjectInternal.getPluginManager()Lorg/gradle/api/internal/plugins/PluginManagerInternal;'. Possible causes for this unexpected error include:<ul><li>Gradle's dependency 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><li>Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.</li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.
解决方法：
1. 访问 https://services.gradle.org/distributions/，并查看最新版的gradle，此文发布时是"gradle-2.10-all.zip"
2. 修改项目中"gradle/wrapper/gradle-wrapper.properties"里下面属性值
... distributionUrl=https://services.gradle.org/distributions/gradle-2.10-all.zip ...
3. 重新执行 gradlew.bat，问题解决
