Android Project 检查依赖库和插件版本

内容简介：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

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.
