Gradle 默认使用 ~/.gradle 目录存放资源, 通过修改环境变量 GRADLE_USER_HOME 可以修改默认目录:

~/.bashrc
export GRADLE_USER_HOME="/dta/programs/gradle"

使用阿里云镜像​

创建文件 $GRADLE_USER_HOME/init.gradle, 内容如下:

allprojects{
    repositories {
        def ALIYUN_REPOSITORY_URL = 'https://maven.aliyun.com/repository/public'
        def ALIYUN_JCENTER_URL = 'https://maven.aliyun.com/repository/public'
        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 }
    }
}

Chrome 为了用户安全, 在检测到网站支持HTTPS协议之后, 会记住该行为, 下次自动使用HTTPS协议, 即便手动输入 http:// 强制访问HTTP也不行.

这时候可以使用无痕模式访问, 或者通过清理 Chrome 对应域名的安全缓存, 解决该问题:

SSH Remote Host Identification has changed​

ssh-keygen -f ~/.ssh/known_hosts -R "[host]:port"

比如 ssh-keygen -f ~/.ssh/known_hosts -R "[www.baidu.com]:8022"
