REST and Integration API

Available in Nexus Repository OSS and Nexus Repository Pro


Nexus Repository Manager leverages a simple UI interface to generate the comprehensive REST documentation from the available endpoints. The REST API can be used to integrate the repository manager with external systems. The interface is fully interactive, where parameters can be filled out and REST calls made directly through the UI to see the results in the browser. 

As of NXRM 3.6.1this interface is available under the API item via the System sub menu of the Administration menu.  

For older versions of NXRM (3.3.0 through 3.6.0), use the following:


A comprehensive listing of REST API endpoints and functionality is documented through the UI. The following highlights noteworthy functionality:

  • Search - component search functionality
  • Assets - direct access the assets/binaries and associated metadata in a repository
  • Components - direct access to language native logical grouping of files in a repository, e.g. maven2 groupId, artifactId, version
  • Script - for provisioning and other complex tasks
  • Tasks - available administrative tasks for the repository manager

Scripting API

Disabled Groovy Scripting By Default


In order to make NXRM more secure, we have disabled Groovy scripting engine by default. This affects Groovy scripts as used through the REST API and through scheduled tasks.

For more information (including how to re-enable Groovy scripting), see NEXUS-23205.

Nexus Repository Manager also provides a scripting API. Scripts can be written to perform custom tasks that can't be handled directly through the UI or the REST API. NXRM scripts are written in the Groovy programming language. More information about Groovy can be found at

There are several methods to run scripts, including:

  • To run a script from the Nexus Repository UI, you must create a scheduled task. Navigate to Tasks from the Administration menu, and create a task of type Admin - Execute script. Enter the script source into the Source form field.  Set the task frequency to Manual (or another setting to execute on a schedule) and save. The script can then be executed by selecting it from the list of tasks and pressing the Run button.
  • A script may be uploaded and run through the REST Script API

Nexus provides the following APIs to scripts:

  • Core API: allows a script to set global configuration options
  • Security API: allows a script to add users, roles, and privileges
  • Blob Store API: allows a script to create new blob stores
  • Repository API: provides a simple, format-specific interface for creating repositories

Sample scripts and javadoc API documentation can be found at
