在Android studio中去编译开源的仓库，大概率就是各种编译不过，一堆错误，一顿改错，基本上会耗费非常多时间，比如：
这个就是改gradle版本，改成7.2 ，修改完成之后，还有其他报错：
Execution failed for task ':app:checkDebugDuplicateClasses'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
> Could not find pub.devrel:easypermissions:0.3.0.
Searched in the following locations:
https://dl.google.com/dl/android/maven2/pub/devrel/easypermissions/0.3.0/easypermissions-0.3.0.pom
https://jcenter.bintray.com/pub/devrel/easypermissions/0.3.0/easypermissions-0.3.0.pom

Searched in the following locations:

project :app
主要原因还是因为国外仓库无法下载，可以使用国内仓库：
allprojects {
repositories {
google()
jcenter()
maven { url 'https://jitpack.io' }
maven { url "https://dl.bintray.com/thelasterstar/maven/" }
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }}
}
最后还是报错， 所以换一种编译方法， 直接在linux系统中编译，当前使用的ubuntu18.04 X86
1， 下载源码
2, 下载sdk
mkdir -p ~/sdk/cmdline-tools
cd ~/sdk/cmdline-tools
wget https://dl.google.com/android/repository/commandlinetools-linux-8512546_latest.zip
unzip commandlinetools-linux-8512546_latest.zip
mv cmdline-tools/ latest
cd ..
echo y | ./cmdline-tools/latest/bin/sdkmanager emulator
echo y | ./cmdline-tools/latest/bin/sdkmanager "platform-tools" "platforms;android-28"
3，设置环境android sdk的环境变量
export ANDROID_HOME=~/sdk
export PATH=~/sdk/cmdline-tools/latest/bin:/home/ctgcdt/sdk/platform-tools:$PATH
4,修改gradle地址，否则下载很慢
cd AndroidCamera/
vim gradle/wrapper/gradle-wrapper.properties
#Fri May 04 17:34:33 CST 2018
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://mirrors.cloud.tencent.com/gradle/gradle-4.4-all.zip
5, 修改依赖仓库， 增加国内阿里仓库，否则很多依赖下载不了
修改文件： AndroidCamera$ vim build.gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
maven { url "https://dl.bintray.com/thelasterstar/maven/" }
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
// classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
maven { url 'https://jitpack.io' }
maven { url "https://dl.bintray.com/thelasterstar/maven/" }
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
~
6，编译
./gradlew
7，根据出错，下载对应sdk
sdkmanager "build-tools;27.0.3"
sdkmanager "platforms;android-27"
8，编译
./gradlew
./gradlew tasks
./gradlew assembleDebug
9， 报错
a, 无法下载EpMedia-v0.9.5.aar
https://jitpack.io/com/github/yangjie10930/EpMedia/v0.9.5/EpMedia-v0.9.5.aar我是通过FQ解决。
9，最后生成apk
./app/build/outputs/apk/debug/app-debug.apk
