Android Project 检查依赖库和插件版本

0x01 问题来源

随着项目的开发,引用的库也不断增加,维护引用的版本也是一个耗时的问题.比如一个项目的依赖库如下:

 compile libraries.supportAppCompat compile libraries.rxJava compile libraries.rxAndroid compile libraries.retrofit compile libraries.retrofitConvertGson compile libraries.retrofitAdapterRxJava compile libraries.okhttp compile libraries.okhttpLogInterceptor compile libraries.okio compile libraries.wire compile libraries.glide

这么多版本,如何检查是否有新版呢?

0x02 查找解决方法

通过Google 查找找到一个问题和答案:

android studio - How to detect when dependency library version updates exist in build.gradle in AndroidStudio project - Stack Overflow

该问题的回答者写了个检测依赖库检查的插件,地址如下:

ben-manes/gradle-versions-plugin: Gradle plugin to discover dependency updates

根据使用说明,对现有的项目改造,即可实现版本检查.

0x03 方案实施

0x031. 修改依赖配置

根据插件的使用说明,将项目的依赖改为以下文件,文件地址:

VersionCheck/dependencies.gradle at master · Dev-Wiki/VersionCheck

 ext {      //编译SDK版本     compileSdkVer = 25     //构建工具版本     buildToolsVer = "25.0.2"     //最低兼容版本     minSdkVer = 14     //测试过的版本     targetSdkVer = 25     //支持库的版本     supportVer = "25.0.0"     //JDK版本     sourceCompatVer = JavaVersion.VERSION_1_7     targetCompatVer = JavaVersion.VERSION_1_7      versions = [         supportVersion:"25.0.0",         supportMultidex : "1.0.1",         junit : "4.12",          gson : "2.6.1",         rxJava : "1.3.0", //         rxAndroid : "1.2.1", //         retrofit : "2.3.0", //         retrofitConvertGson : "2.3.0", //         retrofitAdapterRxJava : "2.3.0", //         okhttp : "3.4.1",//         okhttpLogInterceptor : "3.4.1",         okio : "1.9.0", //         wire : "2.1.2",          glide : "3.7.0",     ]     plugin_versions = [         versions: "0.15.0",     ]      libraries = [         supportAnnotations : "com.android.support:support-annotations:${versions.supportVersion}",         supportAppCompat : "com.android.support:appcompat-v7:${versions.supportVersion}",         supportRecyclerView : "com.android.support:recyclerview-v7:${versions.supportVersion}",         supportDesign : "com.android.support:design:${versions.supportVersion}",         supportCardView : "com.android.support:cardview-v7:${versions.supportVersion}",         supportMultidex : "com.android.support:multidex:${versions.supportMultidex}",         junit : "junit:junit:${versions.junit}",          gson : "com.google.code.gson:gson:${versions.gson}",         rxJava : "io.reactivex:rxjava:${versions.rxJava}", //         rxAndroid : "io.reactivex:rxandroid:${versions.rxAndroid}", //         retrofit : "com.squareup.retrofit2:retrofit:${versions.retrofit}", //         retrofitConvertGson : "com.squareup.retrofit2:converter-gson:${versions.retrofitConvertGson}", //         retrofitAdapterRxJava : "com.squareup.retrofit2:adapter-rxjava:${versions.retrofitAdapterRxJava}", //         okhttp : "com.squareup.okhttp3:okhttp:${versions.okhttp}",//         okhttpLogInterceptor : "com.squareup.okhttp3:logging-interceptor:${versions.okhttpLogInterceptor}",         okio : "com.squareup.okio:okio:${versions.okio}", //         wire : "com.squareup.wire:wire-runtime:${versions.wire}",          glide : "com.github.bumptech.glide:glide:${versions.glide}",     ]     gradle_plugins = [         versions: "com.github.ben-manes:gradle-versions-plugin:${plugin_versions.versions}",     ] }

0x032. 修改项目配置

然后修改项目的 build.gradle ,引入上述的代码,文件在此:

VersionCheck/build.gradle at master · Dev-Wiki/VersionCheck :

 buildscript {     apply from: "${rootDir}/dependencies.gradle"     repositories {         jcenter()     }     dependencies {         classpath 'com.android.tools.build:gradle:2.2.3'         gradle_plugins.each { name, dependency -> classpath dependency }         // NOTE: Do not place your application dependencies here; they belong         // in the individual module build.gradle files     } }  allprojects {     apply from: "${rootDir}/dependencies.gradle"     repositories {         jcenter()     } }  task clean(type: Delete) {     delete rootProject.buildDir }

0x033. 修改module的引用

在 module 的 build.gradle 中添加如下:

 apply plugin: 'com.github.ben-manes.versions' defaultTasks 'dependencyUpdates'   dependencyUpdates.resolutionStrategy = {     componentSelection { rules ->         rules.all { ComponentSelection selection ->             boolean rejected = ['alpha', 'beta', 'rc', 'cr', 'm'].any { qualifier ->                 selection.candidate.version ==~ /(?i).*[.-]${qualifier}[./d-]*/             }             if (rejected) {                 selection.reject('Release candidate')             }         }     } }

如果是多个module还可以直接修改项目的 build.gradle ,将上述内容抽成一个gradle文件 check.gradle ,修改项目的 build.gradle 如下:

 apply from: 'check.gradle' buildscript {     apply from: "${rootDir}/dependencies.gradle"     repositories {         jcenter()     }     dependencies {         classpath 'com.android.tools.build:gradle:2.2.3'         gradle_plugins.each { name, dependency -> classpath dependency }         // NOTE: Do not place your application dependencies here; they belong         // in the individual module build.gradle files     } }  ...

到此,即完成了配置改造.

0x04 执行检测

执行一下命令,来执行检查任务:

 gradle dependencyUpdates

结果如下:

 ------------------------------------------------------------ : Project Dependency Updates (report to plain text file) ------------------------------------------------------------  The following dependencies are using the latest milestone version:  - com.squareup.retrofit2:adapter-rxjava:2.3.0  - com.squareup.retrofit2:converter-gson:2.3.0  - com.github.ben-manes:gradle-versions-plugin:0.15.0  - com.squareup.retrofit2:retrofit:2.3.0  - io.reactivex:rxandroid:1.2.1  - io.reactivex:rxjava:1.3.0  The following dependencies exceed the version found at the milestone revision level:  - com.github.bumptech.glide:glide [3.7.0 <- 3.6.1]  The following dependencies have later milestone versions:  - com.android.support:appcompat-v7 [25.0.0 -> 25.3.1]  - com.android.tools.build:gradle [2.2.3 -> 2.5.0-alpha-preview-02]  - com.squareup.okhttp3:logging-interceptor [3.4.1 -> 3.8.0]  - com.squareup.okhttp3:okhttp [3.4.1 -> 3.8.0]  - com.squareup.okio:okio [1.9.0 -> 1.13.0]  - com.squareup.wire:wire-runtime [2.1.2 -> 2.2.0]

从上述结果可以看出版本有无更新.
