Android Studio下载约束布局失败

Question

我将Android Studio更新为2.1.2,我想下载constraint-layout工具,但它会抛出此消息

要安装: - com.android.support.constraint:constraint-layout-solver:1.0.0-alpha3(extras; m2repository; com; android; support; constraint; constraint-layout-solver; 1.0.0-alpha3) - com .android.support.constraint:constraint-layout:1.0.0-alpha3(extras; m2repository; com; android; support; constraint; constraint-layout; 1.0.0-alpha3)

安装com.android.support.constraint:constraint-layout-solver:1.0.0-alpha3 Maven包路径必须以m2repository开头无法安装com.android.support.constraint:constraint-layout-solver:1.0.0-alpha3!

安装com.android.support.constraint:constraint-layout:1.0.0-alpha3 Maven包路径必须以m2repository开头无法安装com.android.support.constraint:constraint-layout:1.0.0-alpha3!

失败的包: - com.android.support.constraint:constraint-layout-solver:1.0.0-alpha3(extras; m2repository; com; android; support; constraint; constraint-layout-solver; 1.0.0-alpha3) - com .android.support.constraint:constraint-layout:1.0.0-alpha3(extras; m2repository; com; android; support; constraint; constraint-layout; 1.0.0-alpha3)

有没有人和我有同样的问题？如果是的话,你是怎么解决的？
