[GRADLE-1675] slow dependency resolution for certain snapshot dependencies Created: 15/Jul/11  Updated: 04/Jan/13  Resolved: 15/Jul/11

Status: Resolved
Project: Gradle
Affects Version/s: None
Fix Version/s: 1.0-milestone-4

See ticket: http://support.gradleware.com/tickets/1023

git clone --recursive git://git.springsource.org/spring-integration/spring-integration.git
cd spring-integration
./gradlew dependencies

Run again and see the resolution time:
./gradlew dependencies

Edit build.gradle in the project root and change

springVersion = '3.0.5.RELEASE'
springVersion = '3.1.0.BUILD-SNAPSHOT'

./gradlew dependencies

And find out why it is much slower.

The debug log shows a lot of messages like:

[org.gradle.api.internal.artifacts.ivyservice.IvyLoggingAdaper]found module in cache but with a different resolver: discarding: org.springframework#spring-expression;3.1.0.BUILD-SNAPSHOT; expected resolver=http://maven.springframework.org/snapshot; resolver=clientModuleChain

So it looks like our ivy-related code (or ivy) is not using the cache eagerly enough.

It seems the problem was fixed - I browsed through the commits and I think Adam resolved it while working on ivy services. Basically, with latest master, the resolve times are fairly fast regardless for the springVersion.

milestone-3 & '3.1.0.BUILD-SNAPSHOT' : gradle dependencies takes ~ 4 mins
master (soon milestone-4) '3.1.0.BUILD-SNAPSHOT': gradle dependencies takes ~ 1 min

Quite glad to hear this is improving, but even at ~1 min... doesn't that seem like a long time just to resolve/report the dependency graph?

Possibly The resolution may still be slower occasionally, e.g. when snapshots are refreshed, version ranges resolved, etc. However, I'm with you - it should be quick.
