Android：如何更新build.gradle？

Question

I need gradle ver 2.1.4 so I tried changing

classpath 'com.android.tools.build:gradle:2.1.3'

to

classpath 'com.android.tools.build:gradle:2.1.4'

but it didn't work. I also tried this method http://devdeeds.com/update-gradle-plugin-android-studio/ but that didn't work either. This is the error that I am getting

Error:Could not find com.android.tools.build:gradle:2.1.4. Searched in the following locations: file:/C:/Users/Reimu/Downloads/android-studio-ide-145.3200535-windows/android-studio/gradle/m2repository/com/android/tools/build/gradle/2.1.4/gradle-2.1.4.pom file:/C:/Users/Reimu/Downloads/android-studio-ide-145.3200535-windows/android-studio/gradle/m2repository/com/android/tools/build/gradle/2.1.4/gradle-2.1.4.jar https://jcenter.bintray.com/com/android/tools/build/gradle/2.1.4/gradle-2.1.4.pom https://jcenter.bintray.com/com/android/tools/build/gradle/2.1.4/gradle-2.1.4.jar Required by: :MyApp:unspecified

I can't run any projects without this being updated apparently. Any help is appreciated

The classpath 'com.android.tools.build:gradle:2.1.3' is not for Gradle itself, but the Gradle Android build plugin that you apply with the apply plugin: 'com.android.application' or apply plugin: 'com.android.library' in your module's build.gradle file.

If you want to use another version of gradle in your project, reconfigure your gradle wrapper . Search for the /gradle/wrapper/gradle-wrapper.properties file in your project root, and apply the correct distributionUrl , for example:

distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip

For the 2.14.1 version of gradle . This is probably what you need, because there is no such thing as Gradle v. 2.1.4 . There is also no Android Gradle plugin v. 2.1.4 .

And if it turns out, that you need the newest android grade build plugin, then change your class path to 'com.android.tools.build:gradle:2.2.0-beta2' . Version 2.1.3 is currently the newest stable version.
