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:
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.
