项目设置，切换成project 文件视图 gradle/wrapper/gradle-wrapper.properties 里 https\://services.gradle.org/distributions/ 换成下面 https\://mirrors.cloud.tencent.com/gradle/ 并把 url 结尾文件名里的 bin 改成 all

settings.gradle(.kts)里 google {...} 换成 google() ，然后俩 repositories 内都添加

    maven { setUrl("https://maven.aliyun.com/repository/public/") }
    maven { setUrl("https://maven.aliyun.com/repository/google/") }
    maven { setUrl("https://maven.aliyun.com/repository/jcenter/") }
 maven { setUrl("https://maven.aliyun.com/repository/gradle-plugin/") }

关于

大致写下快速写一个 systemd 的定时任务，不使用 cron 是因为 cron 比较弱，而且日志查看不友好。

文件

需要有一个 service 文件和 timer 文件，前者描述启动相关，后者描述定时相关属性

cat &gt; /etc/systemd/system/gitlab-runner.service &lt;&lt; EOF

fork 后本地仓库添加，这里例如 skopeo

先添加上游

git remote add upstream https://github.com/containers/skopeo.git

拉取上游
