android - Volley 不适用于 Gradle 2.0 和 Instant run

Question

我最近将 Android Studio 更新到了 2.0 版:Beta 7。我正在尝试使用 Instant Run，我刚刚安装了 Gradle 2.0。但是现在由于与 bintray.gradle 相关的错误，我无法编译我的项目

编译时出现以下错误:

Error:Cannot configure the 'publishing' extension after it has been accessed.

调试器错误:

Error:FAILURE: Build failed with an exception.

* Where:
Script 'C:\Project\AtkApp\volley\bintray.gradle' line: 43

* What went wrong:
A problem occurred evaluating script.
> Cannot configure the 'publishing' extension after it has been accessed.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

Bintray.gradle :

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath "com.jfrog.bintray.gradle:gradle-bintray-plugin:1.2"
    }
}

// apply the plugin with its class name rather than its Id to work around gradle limitation of
// not being able to find the plugin by Id despite the dependencies being added right above. Gradle
// is currently not capable of loading plugins by Id if the dependency is anywhere else than
// in the main project build.gradle. This file is "imported" into the project's build.gradle
// through a "apply from:".
apply plugin: com.jfrog.bintray.gradle.BintrayPlugin
apply plugin: 'maven-publish'
