Unresolved dependencies error

sbt 0.13.6 will try to reconstruct dependencies tree when it fails to resolve a managed dependency. This is an approximation, but it should help you figure out where the problematic dependency is coming from. When possible sbt will display the source position next to the modules:

[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
[warn]  ::          UNRESOLVED DEPENDENCIES         ::
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
[warn]  :: foundrylogic.vpp#vpp;2.2.1: not found
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
[warn]  Note: Unresolved dependencies path:

Eviction warnings

sbt 0.13.6 displays eviction warnings when it resolves your project’s managed dependencies via update task. Currently the eviction warnings are categorized into three layers: scalaVersion eviction, direct evictions, and transitive evictions. By default eviction warning on update task will display only scalaVersion evictin and direct evictions.

scalaVersion eviction warns you when scalaVersion is no longer effecitive. This happens when one of your dependency depends on a newer release of scala-library than your scalaVersion. Direct evctions are evictions related to your direct dependencies. Warnings are displayed only when API incompatibility is suspected. For Java libraries, Semantic Versioning is used for guessing, and for Scala libraries Second Segment versioning (second segment bump makes API incompatible) is used.

To display all eviction warnings with caller information, run evicted task.

[warn] There may be incompatibilities among your library dependencies.
[warn] Here are some of the libraries that were evicted:
[warn]     * com.typesafe.akka:akka-actor_2.10:2.1.4 -> 2.3.4 (caller: com.typesafe.akka:akka-remote_2.10:2.3.4,
org.w3:banana-sesame_2.10:0.4, org.w3:banana-rdf_2.10:0.4)

#1200/#1467 by @eed3si9n


sbt 0.13.6 adds a new setting key called updateOptions for customizing the details of managed dependency resolution with update task. One of its flags is called lastestSnapshots, which controls the behavior of the chained resolver. Up until 0.13.6, sbt was picking the first -SNAPSHOT revision it found along the chain. When latestSnapshots is enabled (default: true), it will look into all resolvers on the chain, and compare them using the publish date.

The tradeoff is probably a longer resolution time if you have many remote repositories on the build or you live away from the severs. So here’s how to disable it:

updateOptions := updateOptions.value.withLatestSnapshots(false)

#1514 by @eed3si9n

Consolidated resolution

updateOptions can also be used to enable consolidated resolution for update task.

updateOptions := updateOptions.value.withConsolidatedResolution(true)

This feature is specifically targeted to address Ivy resolution is beging slow for multi-module projects #413. Consolidated resolution aims to fix this issue by artificially constructing an Ivy dependency graph for the unique managed dependencies. If two subprojects introduce identical external dependencies, both subprojects should consolidate to the same graph, and therefore resolve immediately for the second update. #1454 by @eed3si9n
