From 8746f5b291ebba7333a505d113592dd9b91ec6f0 Mon Sep 17 00:00:00 2001 From: eureka928 Date: Tue, 3 Mar 2026 01:15:59 +0100 Subject: [PATCH 1/4] [2.x] refactor: Replace ivyModule with Coursier descriptor in evicted task **Problem** The evicted task directly uses ivyModule.value to get a module descriptor. This creates an unnecessary dependency on Ivy for eviction warnings. **Solution** Use dependencyResolution.value.moduleDescriptor() which works with both Ivy and Coursier resolvers, removing the direct Ivy coupling from the eviction checking path.

The ivyless publish task had ivyModule.value and publisher.value calls inside match/case fallback branches. sbt's macro hoists ALL .value calls from ALL match branches as task dependencies regardless of runtime path, causing failures when useIvy=false even for supported repo types. 2. publishM2 used publishOrSkip which errors when useIvy=false, but M2 targets MavenCache which the ivyless path already supports. **Solution** 1. Remove hoisted .value calls from fallback branches in ivylessPublishTask. Replace with direct sys.error calls since these branches handle truly unsupported repo types. 2. Add ivylessPublishM2Task using Def.ifS that publishes to MavenCache via ivylessPublishMavenToFile when useIvy=false.
