在Android studio中使用Jcenter和gradle

Question

编辑：我明白了，我在项目范围的build.gradle文件的allprojects->repositories部分实现了JBaruch的建议。

我正在写一个依赖于IOIO的项目。在我的项目上编译IOIO的libs给我带来了麻烦。我已经尝试将。aar和。jar文件直接放在我的libs/目录中。然而，在gradle中处理。aar文件被证明是一件麻烦的事情。现在，我尝试使用jcenter来查找这些lib。

com.sparetimelabs:purejavacomm:0.0.22

它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')
        */
    }

也就是说，Gradle没有搜索提供的maven url。我怎么强迫Gradle这么做？

com.sparetimelabs:purejavacomm:0.0.22是IOIO项目的传递依赖项。问题是业余实验室有他们自己的存储库，并且不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'
    }  
}
