SBT 1.3.8即使在增量编译时也能自动更新快照版本

Question

由于SBT 1.3.0,Coursier是默认的解析器引擎,因此我们从依赖项中删除了Coursier SBT插件。

在Coursier-plugin时代，我们使用coursier_ttl=“5分钟”来控制自动获取快照版本的频率，即使在开发期间使用sbt~test:compile时也是如此。

对于dependencysnapshot项目，以下是：

2.12\hub_2.12-0.5.0-SNAPSHOT.pom)

在本地.coursier目录中的hub\common2.12\0.5.0-Snapshot下有一个检查过的文件，在使用~test:compile时，在依赖于hub的另一个项目中更改代码时，该文件不会更新。

coursier_ttl在1.3.8中无效。是否有其他方法来设置SBT以频繁检查新的快照版本？

Answer 1

尝试在build.sbt中设置ForceUpdatePeriode持续时间

forceUpdatePeriod := Some(5 minutes)

它控制

Duration after which to force a full update to occur

因为根据运行update的文档，应该可以修复快照的问题

其中2.0.0-RC6-2公开了TTL配置

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

因此，请尝试在build.sbt中进行设置

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

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