Hi fellow Maven users, I have used Maven for 10 years or more and I’m writing with a first. I have a project which was set up in Jenkins with a settings.xml that has updatePolicy set to “never” for a certain repository.
I have experienced that when Maven 3.3.9 fails to resolve an artifact for any reason (could be connection error, the artifact is not there at the time, or any other reason) the first build notes that it will “cache the failure” as follows: Failure to find org.example:foo:jar:0.0.1-RELEASE in https://example.org/foo/repository/ was cached in the local repository, resolution will not be reattempted until the update interval of foo.repository has elapsed or updates are forced Subsequent builds then always fail with log output similar to the below, regardless of whether the connection can be re-established or the dependency is now available: 14:01:07 [ERROR] Failed to execute goal on project foo: Could not resolve dependencies for project org.example:foo:jar:0.0.1-RELEASE: Failed to collect dependencies for org.example:foo:jar:0.0.1-RELEASE: Failed to read artifact descriptor for org.example:foo:jar:0.0.1-RELEASE: Could not find artifact org.example:foo:jar:0.0.1-RELEASE in foo.repository (https://example.org/foo/repository/) …. Unfortunately, I believe the -U flag cannot be used here as it applies to SNAPSHOT dependencies only. An experiment of passing -U further bore this out and did not resolve the issue. My questions here are: 1. Is this the expected behavior for “never” value of updatePolicy? 2. If so, what purpose is this “never” setting meant to serve? What is a valid use case? 3. Is there any way to force the update for a RELEASE artifact when updatePolicy is “never”? Scott
