Jenkins Pipeline Maven Artifactory Plugin Cannot Resolve Artifact From Central Maven Repository

Question

When using a Jenkins Freestyle Project I am able to successfully run a build with Maven using the "Maven3-Artifactory Integration."

When trying to use this feature in pipeline I run into issues with resolving artifacts from the central maven repository. I am under the impression that when Jenkins cannot find an artifact in artifactory it should fall back to the central maven repository,https://repo.maven.apache.org/maven2, to look for the artifact. Is this not the case?

def server = Artifactory.server SERVER_ID
def rtMaven = Artifactory.newMavenBuild()
rtMaven.resolver server: server, releaseRepo: 'my-release-local', snapshotRepo: 'my-snapshot-local'
rtMaven.deployer server: server, releaseRepo: 'my-release-local', snapshotRepo: 'my-snapshot-local'
rtMaven.deployer.artifactDeploymentPatterns.addInclude("").addExclude("")
rtMaven.deployer.deployArtifacts = false
rtMaven.tool = MAVEN_TOOL
def buildInfo = rtMaven.run pom: POM_FILE, goals: GOALS
server.publishBuildInfo buildInfo

From the console output it seems like Jenkins is forcing the build to only resolve artifacts from Artifactory and nowhere else, even though it sees the central repo.

I had the same problem some time ago. I don't know if it applies for you. The flow is what I remember from artifactory:

check on libs-release-local, which we were using for local builds. this has Virtual Repository Associations with libs-release
libs-release is a virtual repo. And Included Repositories under libs-release are libs-release-local AND maven-central-custom
Resolution and upload of artifacts is done to/from libs-release-local. Incase the requred artifact is not available, maven is following libs-release-local --> libs-release --> maven-central-custom

And the following is how we use it inside our jenkinsfile:

// Obtain an Artifactory server instance, defined in Jenkins --> Manage:
def server = Artifactory.server 'localArtifactory'
def rtMaven
def buildInfo

// Artifactory Maven Build instance
rtMaven = Artifactory.newMavenBuild()


rtMaven.tool = 'localMaven'

//where the Maven build should download its dependencies from
rtMaven.resolver server: server, releaseRepo: 'libs-release' , snapshotRepo: 'libs-snapshot'

//define where our build artifacts should be deployed to. we define the Artifactory server and repositories on the 'rtMaven' instance
rtMaven.deployer server: server, releaseRepo: 'libs-release-local', snapshotRepo: 'libs-snapshot-local'


//disable pushing to artifactory, true if requered
rtMaven.deployer.deployArtifacts = false

//By default, all the build artifacts are deployed to Artifactory. So, let's make filter and deployArtifacts=true
rtMaven.deployer.artifactDeploymentPatterns.addInclude("*-common-*")

rtMaven.run pom: 'pom.xml', goals: 'clean package'
rtMaven.deployer.deployArtifacts buildInfo
