Android Project 檢查依賴庫和插件版本

0x01 問題來源

隨著項目的開發,引用的庫也不斷增加,維護引用的版本也是一個耗時的問題.比如一個項目的依賴庫如下:

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

這么多版本,如何檢查是否有新版呢?

0x02 查找解決方法

通過Google 查找找到一個問題和答案:

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

該問題的回答者寫了個檢測依賴庫檢查的插件,地址如下:

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

根據使用說明,對現有的項目改造,即可實現版本檢查.

0x03 方案實施

0x031. 修改依賴配置

根據插件的使用說明,將項目的依賴改為以下文件,文件地址:

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

ext {


//編譯SDK版本
compileSdkVer = 25
//構建工具版本
buildToolsVer = "25.0.2"
//最低兼容版本
minSdkVer = 14
//測試過的版本
targetSdkVer = 25
//支持庫的版本
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}",
]

}</code></pre> 
  
0x032. 修改項目配置
 
  
然后修改項目的 build.gradle ,引入上述的代碼,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
}</code></pre> 
  
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')
            }
        }
    }
}</code></pre> 
  
如果是多個module還可以直接修改項目的 build.gradle ,將上述內容抽成一個gradle文件 check.gradle ,修改項目的 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
    }
}

...</code></pre> 
  
到此,即完成了配置改造.
 
  
0x04 執行檢測
 
  
執行一下命令,來執行檢查任務:
 
  
gradle dependencyUpdates
 
  
結果如下:
 
  
------------------------------------------------------------

: 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]</code></pre> 
從上述結果可以看出版本有無更新.
