How to stop Maven to look for updates on snapshots?

[Francis Yuen <fy...@gmail.com>]

Hi,
I have a project A that depends on an artifact X which is a SNAPSHOT.
Artifact X uses a parent pom X1 which uses a parent pom X2.  Both X1 and X2
are SNAPSHOTs.  Artifact X, X1 and X2 are available from a remote repository
R.

In the pom of project A, I included repository R by defining its id, name
and url.  Artifacts X, X1 and X2 were brought in to my local repository by
running mvn install on the project pom.  I want to be able to stop Maven
from getting updates on artifact X.  On a new day, if I run mvn install in
offline mode, the build fails.  After I build the project in online mode,
subsequent builds on the same day can be run in offline mode.  I did a
couple of tests:

Test 1.
I advanced the date to a day later than today and then ran "mvn -o -e
install".  The build failed and the error was that X was missing.  The error
messages suggested to download X manually from the project site and then
install it using mvn install:install.

Test 2.
In the pom of project A, I added
<snapshots><updatePolicy>never</updatePolicy></snapshots> to respository
section of R.  I advanced the date to a day later and then ran "mvn -o -e
install".  The build failed.  The message thrown by
org.apache.maven.artifact.resolver.ArtifactResolutionException indicated
that it was unable to read the metadata file for artifact X: Cannot find
parent X2 for X1 for X.

It looks like that in Test 1, Maven did not see X to be in my local
repository.  In Test 2, by introducing repository snapshot never update
policy in the project pom, Maven seems to see X and X1 but not X2.

I am fairly new to Maven.  Can someone tell me how to stop Maven to look for
updates on snapshots (or its parent pom)?

Hi,

It seems that the offline mode does not work with SNAPSHOT.
You also have this issue : http://jira.codehaus.org/browse/MNG-3314

It looks like this issue : http://jira.codehaus.org/browse/MNG-2433
It is supposed to have been corrected with Maven 2.0.6, but I still have the
problem with Maven 2.0.8 and it happened to me when doing a demonstration
with no internet connection, not funny at all.
This issue has to be reopened !
