问题：gradle下载缓慢
解决：使用阿里云仓库，在C:\Users\***\.gradle\wrapper\dists\gradle-6.4.1-bin\***\gradle-6.4.1\init.d这个目录下新建init.gradle文件，内容：
allprojects{
repositories {
def ALIYUN_REPOSITORY_URL = 'https://maven.aliyun.com/repository/public/'
def ALIYUN_JCENTER_URL = 'https://maven.aliyun.com/repository/jcenter/'
def ALIYUN_GOOGLE_URL = 'https://maven.aliyun.com/repository/google/'
def ALIYUN_GRADLE_PLUGIN_URL = 'https://maven.aliyun.com/repository/gradle-plugin/'
all { ArtifactRepository repo ->
if(repo instanceof MavenArtifactRepository){
def url = repo.url.toString()
if (url.startsWith('https://repo1.maven.org/maven2/')) {
project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."
remove repo
}
if (url.startsWith('https://jcenter.bintray.com/')) {
project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL."
remove repo
}
if (url.startsWith('https://dl.google.com/dl/android/maven2/')) {
project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_GOOGLE_URL."
remove repo
}
if (url.startsWith('https://plugins.gradle.org/m2/')) {
project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_GRADLE_PLUGIN_URL."
remove repo
}
}
}
maven { url ALIYUN_REPOSITORY_URL }
maven { url ALIYUN_JCENTER_URL }
maven { url ALIYUN_GOOGLE_URL }
maven { url ALIYUN_GRADLE_PLUGIN_URL }
}
}
