Question

I can’t get Ivy to update cache when snapshot dependencies are updated. The resolver (to has the following settings:

<url name="xxx" m2compatible="false" 
     checkmodified="true" changingMatcher="regexp" 
     changingPattern=".*-SNAPSHOT.*">

An example artifact filename (in Artifactory) is:

my-jar-1.999-SNAPSHOT.jar

A detailed Ant log of resolve includes:

[NOT REQUIRED] com.myorg#my-module;1.999-SNAPSHOT!my-jar.jar

There is no POM on the artifact.

The resolver is underneath a chain resolver; they both have all the relevant attributes set. I have read https://issues.apache.org/jira/browse/IVY-938 and https://issues.apache.org/jira/browse/IVY-1221, including all the comments, and AFAICT (perhaps incorrectly!) none of the workarounds are relevant.

Should I give up on snapshots and just use explicit versions with “integration.latest” dynamically versioned dependencies? I fear this may end up failing when we have integration builds happening for multiple major versions. At that point we’ll need to split the major versions out into separate repositories, or put the major build number in the artifact name, or something equally clunky, just to make “integration.latest” work.

After days of struggle…

The problem was that for

checkmodified="true" changingMatcher="regexp"

to work on a <resolver>, it has to be on every resolver in the hierarchy line – all parent <chain> resolvers and the <url>, <local>, or <ibiblio> resolver at the bottom.
