CodeArtifact+Maven Idea plugin

Idea plugin: https://plugins.jetbrains.com/plugin/16777-aws-codeartifact--maven

Source: Github: https://github.com/coderazzi/aws_codeartifact_maven

This plugin facilitates accessing and deploying artifacts in CodeArtifact on Maven Intellij Idea projects.

AWS provides very specific instructions to setup Maven to support AWS CodeArtifact. Basically, your file ~/.m2/settings.xml must include a server specification such as:


The token CODEARTIFACT_AUTH_TOKEN needs to be refreshed every 12 hours (by default) by doing:

export CODEARTIFACT_AUTH_TOKEN=`aws codeartifact get-authorization-token --domain DOMAIN \
      --domain-owner DOMAIN_OWNER --query authorizationToken --output text`

After issuing the previous command, the environment that executes the command has authorized access to CodeCommit

The main problem here is that when using an IDE like IDEA, you would need to update the CODEARTIFACT_AUTH_TOKEN environment variable and then launch the IDE. And as the token needs to be refreshed, it is needed to quit the IDE and repeat the process every 12 hours. Plus, it is needed to update the environment variable in the same environment where the IDE is launched, quite inconvenient if launching the IDE from anywhere except the command line.

Idea allows to setup environment variables for MVN execution (under Settings/Build/Execution/Deployment/Build Tools/Maven/Runner), but this would imply to manually obtaining the token and updating the setting periodically.

A better option for this specific scenario is to automatically update the password in ~/.m2/settings.xml, to reflect the real token. That is, the settings file will look like:


CodeArtifact-Maven Idea plugin does exactly this simple task. Note that there is a AWS-supported AWS plugin, but it does not cover getting credentials for CodeArtifact


The plugin is available in Intellij Idea public plugin repository, as CodeArtifact+Maven.


After installation, a menu entry appear under Tools: Generate AWS CodeArtifact credentials for Maven

When selected, a window appears to enter the required details:

  • Domain: the domain in AWS
  • Domain Owner: the account owner, something like 023174738914
  • Maven server id: the server name provided in your maven settings file -as following the instructions from AWS-. Starting on version 2.0, this is a dropdown menu, pre-filled with the values obtained from the maven settings file: it extracts all the servers where the username is aws
  • AWS profile: the profile to use to obtain the credentials, obtained from any of the files <USER-HOME>/.aws/config, <USER-HOME>/.aws/credentials, <AWS_CONFIG_FILE>, <AWS_SHARED_CREDENTIALS_FILE>
  • Maven settings file: the location of the maven settings file, usually under ~/.m2
  • AWS cli path: the location of the aws executable, can be specified as aws if it can be found in the path

The button Generate credentials will initiate the requests of a token to AWS and its inclusion in the maven settings file

MFA support

From version 3.0.0, the plugin includes support for MFA, prompting the user to enter the MFA token if required.

Currently, only MFA based on roles is supported, where the chosen profile identifies a IAM role, not a IAM user.
