我不明白为什么会这样。

Gradle sync failed: Timeout waiting to lock buildscript class cache for build file '/Users/user/Documents/android-studio-pubble/App/build.gradle' (/Users/user/.gradle/caches/2.2.1/scripts/build_bqh4uod6cat7u5cm5qkoye2ky/ProjectScript/buildscript). It is currently in use by another Gradle instance.

grad尔将军是：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        maven { url '/Users/user/Documents/sdk/extras/android/m2repository' }

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
    }
    tasks.withType(JavaCompile) {
        options.compilerArgs << "-Xlint:deprecation" << "-Xlint:unchecked"

它曾经工作，然后我想添加一个新的模块，它都走下坡路后，有人有这个问题，并解决了它？我甚至不知道是什么错了..或我如何使这一点。
