从Android Gradle plugin 2.2.0开始，gradle会自动加载需要的SDK, build-tools，但是因为没有接受license，导致加载依赖终止，提示

* What went wrong:
A problem occurred configuring project ':app'.
> You have not accepted the license agreements of the following SDK components:
[Android SDK Build-Tools 24.0.2].

Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager.

Alternatively, to learn how to transfer the license agreements from one workstation to another, go to http://d.android.com/r/studio-ui/export-licenses.html

有什么办法自动接受所有的license呢？

问题解决

license存放在$ANDROID_HOME/licenses下

创建license

Linux

mkdir "$ANDROID_HOME/licenses"
echo -e "\n8933bad161af4178b1185d1a37fbf41ea5269c55" > "$ANDROID_HOME/licenses/android-sdk-license"

Windows

mkdir "%ANDROID_HOME%\licenses"
echo |set /p="8933bad161af4178b1185d1a37fbf41ea5269c55" > "%ANDROID_HOME%\licenses\android-sdk-license"
