This is an epic to track migration to Coursier as the internal library management engine. #4614

• URL follow redirect - library dependency with from does not follow redirects #2609, SBT 1.0.2 fails to fetch dependencies from maven.twttr.com #3670
• latest-wins on Maven Central origin artifacts - Is there a way to make transitive dependency conflicts resolve to the latest version? #3525
• multiple version ranges - Maven Version Range Sets in Transitives Do Not Work #2647, multiple range versions don't resolve correctly #4271
• specific version over version range - Transitive dependency causes wrong evictions #2291

explicit URL using from(...)

There was a bug in earlier version of Coursier 2.0 beta, but since 2.0.0-RC2-1, there's been scripted test called dependency-management/url that tests for this feature. However there's been some report that it's not working.

• Explicit URL using from not working as expected Explicit URL using from not working as expected #5418 / libraryDependencies += dependency from "some url" not working with sbt version 1.4.5 #6293

proxy

- proxy with basic authentication not working #5307 / coursier/coursier#930

dependency graph regression

- Test resolution leaks over to Compile configuration, evicting Compile dependencies - coursier/coursier#1382

other regressions

• classpath is no longer topologically sorted Change in classpath ordering using Coursier #5282 / Change in classpath ordering compared to Ivy coursier/coursier#1466
• unresolved resolution graph error unresolved resolution graph error #5168
• java.lang.NumberFormatException: For input string: "h7v0l43" java.lang.NumberFormatException: For input string: "h7v0l43" #5218
• "org.nd4j" % "nd4j-native-platform" % "1.0.0-beta4" resolves to an URL with ${project.packaging} - URISyntaxException downloading managed dependency due to unresolved ${project.packaging} #5046
• Basic auth handling - [1.3.0] Nexus repo credentials not used when downloading dependencies/custom plugin #4852 (has PR Basic auth is not supposed to be case sensitive coursier/coursier#1350)
• Transitive dependencies with classifier are not downloaded Transitive dependencies with classifier are not downloaded coursier/coursier#1455
• a transitive non-optional dependency that is optional in its parent POM is missing - [1.3.0-RCx] a transitive non-optional dependency, but optional in parent POM, is missing #4968 (also a transitive non-optional dependency that is optional in its parent POM is missing coursier/coursier#1336. it might be a "won't fix" because MNG-5227 says it's correct?)
• updateFull is missing caller for direct dependencies [1.3.0] updateFull is missing caller for direct dependencies #4706

@eed3si9n surely this can be closed now 😀
