Gradle Build 构建 & Maven Repositories & Artifacts - 知名开源项目库、仓库POM文件 | Jib Plugin

综合/最新

Kotlin变量声明：并非var而是 val k=v

Kotlin导入类：必须写在顶部 - import java.time.Instant 使用 - Instant.now().toString().replace(":", "_")

操作文件前判断是否存在：即Kotlin的三元表达式
  val txtFile=file("../../../../docs/cloud/project-123456.json")
  password = if (txtFile.exists()) txtFile.readText() else null
