在 Android studio 中将 Jcenter 与 gradle 一起使用

Using Jcenter with gradle in Android studio

编辑:弄清楚了,我对项目范围 build.gradle 文件的 allprojects->repositories 部分实施了 JBaruch 的建议。

我正在编写一个依赖于 IOIO 的项目。在我的项目上编译 IOIO 的库给我带来了麻烦。我尝试将 .aar 和 .jar 文件直接放在我的 libs/ 目录中。然而,在 gradle 中使用 .aar 文件被证明是一个麻烦事。现在,我正在尝试使用 jcenter 来查找这些库。

使用jcenter作为我的仓库,gradle原来无法解决

com.github.ytai.ioio:IOIOLibCore

但指定版本号 5.05 解决了这个问题。但是,现在 gradle 无法解析

com.sparetimelabs:purejavacomm:0.0.22

这不是我要求与我的项目一起编译的库。

下面是我的 app/build.gradle 文件的副本

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.example.agrc.elkausbtransfer"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
        compile 'com.android.support:appcompat-v7:23.0.1'
        compile 'com.github.ytai.ioio:IOIOLibCore:5.05'
        compile 'com.github.ytai.ioio:IOIOLibPC:5.05'
        compile 'com.github.ytai.ioio:IOIOLibAndroid:5.05'
        compile 'com.github.ytai.ioio:IOIOLibAndroidAccessory:5.05'
        compile 'com.github.ytai.ioio:IOIOLibAndroidDevice:5.05'
        /* To use IOIO from source
        compile fileTree(dir: 'libs', include: ['*.jar'])
        compile(name: 'IOIOLibAndroid-release', ebxt: 'aar')
        compile(name: 'IOIOLibAndroidAccessory-release', ext: 'aar')
        compile(name: 'IOIOLibAndroidDevice-release', ext: 'aar')
        */
    }

在尝试了 JBaruch 的建议并将 maven url 添加到我的项目(根)build.gradle 文件后,我注意到 Gradle 构建文件如下所示:

    Executing tasks: [:app:assembleDebug]

Configuration on demand is an incubating feature.

即 Gradle 没有在提供的 maven url 中搜索。我如何强制 Gradle 这样做?

com.sparetimelabs:purejavacomm:0.0.22是IOIO项目的传递依赖。问题是 Spare time labs 有自己的存储库,不会将他们的工件发布到 Bintray。您需要做的是将他们的存储库添加到 Gradle:

中的存储库列表中
repositories {
    jcenter()
    maven {
       url 'http://www.sparetimelabs.com/maven2'
    }  
}
buildscript {
repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:4.0.1'
    
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}
allprojects {
repositories {
    google()
    jcenter()
}
}
