Answer 1

From your error details,

Failed to transfer file: http://*******/artifactory/ext-snapshot-local/lcmsdaomodel/lcms.dao.model/1.1.1/lcms.dao.model-1.1.1.pom.
Return code is: 409 , ReasonPhrase:Conflict. -> [Help 1]

You have deployed a release version of lcms.dao.model in ext-snapshot-local which is only used to deploy manual snapshot of libraries. Check artifactory documentation.

1. If lcms.dao.model is a released artifact, then login into your artifactory and delete entry for this library in Artifacts -> Tree Browser -> ext-snapshot-local. You need to have released version of this library in your artifactory.
2. If this is snapshot version, you need to version your library as 1.1.1-SNAPSHOT

Answer 2

I received this error with the archiva repository directory of the artifact being incorrectly set such that archiva didn't have write access.

Answer 3

I have the same error, I was deploying snapshot and snapshotRepository settings was not included in my main pom's distributionManagement. fix by adding snapshotRepository

    <distributionManagement>
    <snapshotRepository>
        <id>snapshots</id>
        <name>libs-snapshot</name>
        <url>http://artifactory.private-apps.com/artifactory/libs-snapshot-local</url>
    </snapshotRepository>
</distributionManagement>

Answer 4

I had this problem and clearing out my .m2 directory fixed it.

Answer 5

It seems that you are trying to resolve RELEASE artifact from a SNAPSHOT repository, therefore Artifactory is sending an error (409 conflict).

You should direct your build to 'libs-releases' virtual repository, or any other virtual repository that holds only releases, so only repositories that hold release artifacts will be involved in the process of RELEASE artifact resolution
