找不到recyclerview-v7.jar（com.android.support:recyclerview-v7:28.0.0)

时间：2018-12-11 11:13:00

标签： android gradle android-recyclerview nativescript

我是Android开发的新手。为此，我选择了NativeScript。

在一种情况下，我需要使用RadListView，因此将其插件添加到了我的应用程序中。但是当我尝试运行该应用程序时，出现此错误：

FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all files for configuration ':app:debugCompileClasspath'.
> Could not find recyclerview-v7.jar (com.android.support:recyclerview-v7:28.0.0).
  Searched in the following locations:
  https://dl.google.com/dl/android/maven2/com/android/support/recyclerview-v7/28.0.0/recyclerview-v7-28.0.0.jar

https://dl.google.com/dl/android/maven2/com/android/support/recyclerview-v7/28.0.0/recyclerview-v7-28.0.0.jar返回404错误。

如何复制： 

> tns create my-app --template tns-template-hello-world
> cd my-app
> tns run android
> tns plugin add nativescript-ui-listview
> tns run android

第一个run可以，第二个则不能。

最接近我的问题的页面是this。但是他可以通过升级gradle解决他的问题。我已经有了它的最新版本。

我的 build.gradle（根目录）：

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

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我的 build.gradle（应用程序）：

/*
*   Script builds apk in release or debug mode
*   To run:
*           gradle assembleRelease -Prelease (release mode)
*           gradle assembleDebug (debug mode -> default)
*   Options:
