Gradle依赖配置&命令备忘录

1. 强制设置gradle依赖版本号

android{
  ...
}
...
configurations.all {
    //强制recyclerview版本号为1.1.0-beta03
    resolutionStrategy.eachDependency { details ->
        def requested = details.requested
        if (requested.group == "androidx.recyclerview" && requested.name == 'recyclerview') {
            details.useVersion('1.1.0-beta03')
        }
    }
}
...

2. 刷新依赖

gradle build --refresh-dependencies

3. AndroidStudio右上角的Gradle里不显示Task

问题如图，不显示Task，只显示依赖（图片上传失败）
解决方式：依次点击：File -> Settings -> Experimental -> 取消勾选 “Do not build Gradle task list during Gradle sync”保存设置再次同步项目

4. Android Studio一直build model

可以将gradle文件中的 "jcenter()" 和 "mavenCentral()"全部注释掉，换成阿里的镜像，如下:

buildscript {
    repositories {
        //jcenter()
       //mavenCentral()
        maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        google()
    }
    dependencies {
        ...
    }
}

allprojects {
    repositories {
        google()
        //jcenter()
        //mavenCentral()
        maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}
    }
}

5.AndroidStudio编译时报OOM

可以将项目顶级目录下的gradle.properties文件中的Xmx参数调大，意思是调大JVM允许分配的最大堆内存，具体如下：

# Gradle settings configured through the IDE *will override*
# any settings specified in this file.
# For more details on how to configure your build environment visit
# http://www.gradle.org/docs/current/userguide/build_environment.html
# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
#org.gradle.jvmargs=-Xmx1536m -Dfile.encoding=UTF-8
#调大，换成4096
org.gradle.jvmargs=-Xmx4096m -Dfile.encoding=UTF-8
# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
# org.gradle.parallel=true
# AndroidX package structure to make it clearer which packages are bundled with the
# Android operating system, and which are packaged with your app's APK
# https://developer.android.com/topic/libraries/support-library/androidx-rn
android.useAndroidX=true
# Automatically convert third-party libraries to use AndroidX
android.enableJetifier=true

其中可调的参数有Xms、Xms等，可以参考该文章：Xms Xmx PermSize MaxPermSize 区别
