将 gradle 缓存转换为本地 maven 仓库及上传到 nexus

gradle 将 maven 仓库中的所有依赖库下载到本地缓存文件夹中。但是此缓存文件夹不可移植。如果我们将此缓存文件夹从我们的 PC 传输到另一台 PC，gradle 将无法识别 gradle 缓存的复制版本。同时我们无法简单的做到将缓存的 gradle 上传到 nexus 中

事情的起因是我依赖的 https://artifacts.alfresco.com/nexus/content/repositories/ 突然需要进行 HTTP Basic 认证，导致我的打包脚本无法正常执行，所以我要将本地缓存的相关包转移到 nexus 中去

将 gradle cache 转换为 maven local

通过搜索 github，找到了 gradle-cash-to-maven-repo

通过此代码（python3）可以很方便将 gradle cache 转换为 maven local

#           This local maven repository can be used in gradle offline build directly instead of gradle cache.
