Android Studio 3.0

今天突然想起以前弄过的Cordova，于是便下来重新玩玩，一开始Android Studio还没更新，一切正常。然而当我选择确定更新为3.0并同时更新了gradle后，项目竟然开始报错

unable to resolve dependency for cordovalib...打开build.gradle看了后其中dependencies是这样写的

dependencies {
   compile fileTree(dir: 'libs', include: '*.jar')
    // SUB-PROJECT DEPENDENCIES START
   debugCompile(project(path: "CordovaLib", configuration: "debug"))   releaseCompile(project(path: "CordovaLib", configuration: "release"))
    // SUB-PROJECT DEPENDENCIES END}

感觉没毛病，非常nice，于是特地查了下3.0版的dependencies是否有变动，一查果然有妖孽作祟，如果你没有一个libary项目，原来的写法并不会有问题，但加入一个lib的写法

需做如下改动

dependencies {
    implementation fileTree(dir: 'libs', include: '*.jar')
    // SUB-PROJECT DEPENDENCIES START
//    debugCompile(project(path: "CordovaLib", configuration: "debug"))
//    releaseCompile(project(path: "CordovaLib", configuration: "release"))
    // SUB-PROJECT DEPENDENCIES END
    implementation project(':CordovaLib')
    debugImplementation project(':CordovaLib')
    releaseImplementation project(':CordovaLib')
}

将compile替换成implementation即可完美解决上述问题，至于为何官方要做这个改动，原因可以去官网看看，或者是看这篇博客安卓工程依赖方式
