IntelliJ Maven Not Resolving Dependencies / Not Applying Excludes

I recently had a ton of issues with dependencies in IntelliJ with maven, on multiple consecutive occasions. This is pretty odd as I’ve used IntelliJ and Maven for probably around 10 years (I even have the top youtube videos on that combination!).

I’m on IntelliJ 2020.1 currently, and I found a few things through painful trial and error here. I hope they help you.

  1. Apparently at some point they removed that “Automatically Import” option that used to pop up when you created/imported a maven project. This used to make things automatically resolve as you changed your POM. Now you need to make sure you build to pull in dependencies, and for safe measure I also click the “re-import” button on the maven tools tab (little icon at the top row).
  2. There is now an “offline” mode. So, you may keep failing and failing to install because you can’t resolve dependencies on, say, maven central. This is super confusing as you may actually be online and looking at maven central and seeing the dependencies there. If this happens, check/disable offline mode!
  3. You may add excludes to a complex dependency (like the hive metastore in my case) to remove transitive dependencies that break your app/framework (like spring boot). You shold make sure to change the POM, clean, and then re-import the maven project again to ensure they’re really gone. I kept seeing them in the external dependencies list in the object browser, and my builds were failing, until I did the last step of re-importing.
  4. If all else fails, clean, invalidate-and-restart (in the file menu), install, and re-import and it seems to be a good catch-all for when you’re completely lost.

This all seems pretty crazy to me, but I’ve gone through it a few times now and it seems right. I hope it helps you save some of the time I wasted!

Artifactory + Maven Deploy +/- Jenkins – 502 Failure

This is just a quick post…

If you are running a maven (mvn) deploy to artifactory, be it locally or through Jenkins/etc, and you get an error like this:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy (default-deploy) on project sample-ws: Failed to deploy artifacts: Could not transfer artifact from/to central ( Failed to transfer file with status code 502 -> [Help 1]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR] For more information about the errors and possible solutions, please read the following articles:
[ERROR] [Help 1]

You need to edit your ~/.settings.xml and add in your artifactory-user/artifactory-token (preferably for you on your own desktop and for a service account on your server).  You can generate your token in your user settings in the Aritfactory API.


Jenkins Pipeline – Maven + Artifactory Example With Secure Credentials

There are always a million ways to do things in Jenkins, but often using the appropriate plugins for common tools pays off a lot.  Here is an example of using multiple maven commands to execute a build, the result of which (a zip file) is then uploaded to Artifactory.

Sample Pipeline

Honestly, there will almost definitely be an artifactory plugin as well; but in this case, I used these 2 plugins:

  • Pipeline Maven Integration Plugin – Allows you to target various maven installations set up in your Jenkins “Global Tool Configuration”.
  • Credentials Binding Plugin – Allows you to pull user names and passwords from credentials into environment variables to use in commands easily.

This was enough to let me run the maven commands I needed and to let me then call the Artifactory REST API safely to upload my one artifact, which is a zip in this case.

I hope this example helps you! 🙂

pipeline {
    agent any
    parameters {
        string(name: 'SOURCE_BRANCH', defaultValue: 'master', description: '...')
        string(name: 'RELEASE_TAG', defaultValue: '', description: '...')
    stages {
        stage('Build and deploy presto zip to artifactory.') {
            steps {

                sh 'echo "Building to version = $RELEASE_TAG"'

                withMaven(maven: 'maven-3') {
                  sh "mvn versions:set -DnewVersion=$RELEASE_TAG"
                  sh "mvn clean install -DskipTests"

                withCredentials([usernamePassword(credentialsId: 'artifactory-token', usernameVariable: 'AUSR',
                    passwordVariable: 'APWD')]) {
                  sh '''curl -X PUT -u $AUSR:$APWD -T presto-server/target/presto-server-$RELEASE_TAG.tar.gz "$RELEASE_TAG/presto-server-$RELEASE_TAG.tar.gz" '''
                sh 'echo "Done building and tagging to name = $RELEASE_TAG"'

Jenkins Pipeline Maven /Build + Deploy to Nexus/Artifactory in Docker


If you want to use a Jenkins pipeline to build your maven project in a clean docker container, you can do so as shown below.

You can do any maven commands you like.  In this particular case I am:

  • Setting the version in the POM to the one provided by the person running the Jenkins job.
  • Building and deploying the maven project to Artifactory.

This is the “build one” of “build once deploy everywhere”.

To test this though, you can just swap my commands out for maven –version or something simple like that.


Create  a new pipeline job and:

  1. Add a string parameter called VERSION_TO_TAG.
  2. Set pipeline definition to “Pipeline script from SCM”.
  3. Give your repo checkout URL – e.g. ssh://
  4. Specify your git credentials to use.
  5. Specify your Jenkinsfile path (It is probably literally just “Jenkinsfile” which is the default if you have the Jenkinsfile in the root of your repo).

Make sure your project has a “Jenkinsfile” at its root with a definition like this:

pipeline {
    agent {
        docker { image 'maven:3-alpine' }

    stages {
        stage('Set version, build, and deploy to artifactory.') {
            steps {
                sh 'mvn versions:set -DnewVersion=$VERSION_TO_TAG'
                sh 'mvn deploy'

Now, when you build your project, you should see it docker-pull a maven:3-alpine image, start the container, and run our maven commands and upload artifacts to the Artifactory repository you have set up in your maven POM (in your distributionManagement section in case you haven’t done that yet).
