即使在增量编译中，SBT 1.3.8 也会自动更新 SNAPSHOT 版本

Question

从 SBT 1.3.0 开始，Coursier 是默认解析器引擎，因此我们从依赖项中删除了 Coursier SBT 插件。

在 Coursier-plugin 时代，我们曾经COURSIER_TTL="5 min"控制过SNAPSHOT自动获取版本的频率，甚至sbt ~test:compile在开发过程中何时使用。

对于依赖SNAPSHOT项目，这里是输出：

sbt:hub> show isSnapshot
[info] common / isSnapshot
[info]  true
[info] isSnapshot
[info]  true

hub\common_2.12\0.5.0-SNAPSHOT本地.coursier目录下有一个 CHECKED 文件hub，当使用~test:compile.

COURSIER_TTL在 1.3.8 中没有影响。有没有其他方法可以设置 SBT 以经常检查新SNAPSHOT版本？

Answer 1

尝试forceUpdatePeriod在build.sbt

forceUpdatePeriod := Some(5 minutes)

哪个控制

Duration after which to force a full update to occur

因为根据运行的文档update应该可以解决 SNAPSHOT 的问题

显式运行更新。这通常会解决过时的快照或本地发布的工件的问题。

编辑：尝试更新到SBT 1.3.9哪些

更新 lm-coursier-shaded 2.0.0-RC6-2

其中2.0.0-RC6-2公开 TTL 配置

现在可以通过 CoursierConfiguration 调整 TTL、详细级别、校验和和缓存策略，可通过 sbt 中的 csrConfiguration 访问。

因此尝试设置 build.sbt

import scala.concurrent.duration.DurationInt
import lmcoursier.definitions.CachePolicy

csrConfiguration := csrConfiguration.value
  .withTtl(1.minute)
  .withCachePolicies(Vector(CachePolicy.LocalOnly))
