Maven / Nexus not picking up the latest version of SNAPSHOT artefact

[Mehul Sanghvi]

Maven:  3.3.3

Nexus: 2.14.5-02

We have a product made up of several components:

   Comp1 -> Comp2 -> Comp3 -> Comp4 -> Product

That is the order of dependencies for the builds.  Each component uploads

some JARs to Nexus using Maven deploy:deploy-file.  What we are seeing

is that the latest artefacts that are uploaded to Nexus are not being

picked up by subsequent components and the product.  They are all

using -SNAPSHOT versions,  as they should be.  I will try to

illustrate with an example.

I have the following:

 Comp3-artefact-1.2.3.4.5-20170820-080555-18-all.zip

 Comp3-artefact-1.2.3.4.5-20170821-080423-19-all.zip

 Comp3-artefact-1.2.3.4.5-20170822-075728-20-all.zip

 Comp3-artefact-1.2.3.4.5-20170823-075717-21-all.zip

on my Nexus server, that I see using the web-ui.

When I build the Product, it should pick up the *-21-all.zip artefact

as that is the latest.  What happens though is that it picks up the

*-20-all.zip artefact.  I have to manually rebuild the metadata and

rebuild the index through the Nexus webui and than re-start the build

for it to pick up the latest version.

This is true regardless of what component it is, and also is showing up

in between the Components as well.

Is this an indexing issue ?  Is it in Maven or Nexus ?  And what

should I do to fix it ?

cheers,

What is the updatePolicy set to in your repository definition for snapshots in your settings.xml?  You should have it set to "always".

Rich,

    Yes sorry forgot to mention that the update policy is "always"

                <repository>

                    <id>snapshots</id>

                    <name>Internal Nexus Snapshots</name>

                    <url>http://nexus.mycorp.com:8081/nexus/content/groups/snapshots</url>

                    <releases>

                        <enabled>false</enabled>

                    </releases>

                    <snapshots>

                        <enabled>true</enabled>

                        <updatePolicy>always</updatePolicy>

                    </snapshots>

                </repository>

And here is a sample of the command being used for deploying the artefacts:

mvn deploy:deploy-file -B -V --quiet -s /path/to/settings.xml -PComp4-profile -Dmaven.repo.local=/path/to/repo-comp4-nightly -Dsettings.security=/path/to/settings-security.xml -DgeneratePom=true -Dclassifier=all -DrepositoryId=comp4-snapshots -Durl=http://nexus.mycorp.com:8081/nexus/content/repositories/comp4-snapshots -DgroupId=com.mycorp.mygroup -Dversion=1.2.3.4.5-SNAPSHOT -DartifactId=Comp4-artefact -Dfile=path/to/target/Comp4-artefact-1.2.3.4.5-SNAPSHOT-all.zip

cheers,
