Also, there is a good amount of information available at Bundle Development


To build the project and generate the bundle use Maven

mvn clean install

If everything checks out, the bundle for R should be available in the target folder

Build with Docker

docker build -t nexus-repository-r .

Run as a Docker container

docker run -d -p 8081:8081 --name nexus-repository-r nexus-repository-r

Please view detailed instructions on how to get started here!

Compatibility with Nexus Repository Manager 3 Versions

The table below outlines what version of Nexus Repository the plugin was built against:

v1.0.1 >=3.8.0-02
v1.0.2 >=3.14.0-04
v1.0.3 >=3.15.2-01

All released versions can be found here.

Installing the plugin

In Nexus Repository Manager 3.20+ R format is already included. So there is no need to install it. But if you want to reinstall the plugin with your improvements then following instructions will be useful.
Note: Using an unofficial version of the plugin is not supported by the Sonatype Support team.

Permanent Reinstall

  • Copy the new bundle into <nexus_dir>/system/org/sonatype/nexus/plugins/nexus-repository-r/1.1.1-SNAPSHOT/nexus-repository-r-1.1.1-SNAPSHOT.jar

  • Edit <nexus_dir>/system/org/sonatype/nexus/assemblies/nexus-cma-feature/3.x.y/nexus-cma-feature-3.x.y-features.xml changing R to your snapshot version (examples, the actual lines surrounding may vary):

          <feature version="1.a.b">nexus-repository-p2</feature>
          <feature version="1.1.1.SNAPSHOT">nexus-repository-r</feature>
          <feature version="3.x.y.xy">nexus-repository-raw</feature>


    + <feature name="nexus-repository-r" description="nexus-repository-r" version="1.1.1.SNAPSHOT">
    +     <bundle></bundle>
    + </feature>

This will cause the plugin to be loaded and started with each startup of Nexus Repository.

NOTE: The file location changed in version 3.21. For older versions, edit these files:

  • If you are using OSS edition, make these mods in: <nexus_dir>/system/com/sonatype/nexus/assemblies/nexus-oss-feature/3.x.y/nexus-oss-feature-3.x.y-features.xml
  • If you are using PRO edition, make these mods in: <nexus_dir>/system/com/sonatype/nexus/assemblies/nexus-pro-feature/3.x.y/nexus-pro-feature-3.x.y-features.xml Additionally, prior to 3.21 the lines did not exist so they'd need to be added instead of edited.

Easiest Install for version

Nexus Repository Manager 3.20+ already includes the R plugin. If you want to install an old R plugin in an old Nexus Repository Manager, the instructions below may be useful. However, we strongly recommend you update to the latest Nexus Repository version. If you are developing new features for R plugin and want to install your new R plugin, then follow the instructions below.

Thanks to some upstream work in Nexus Repository (versions newer than 3.15), it's become a LOT easier to install a plugin. To install the R plugin, you can either build locally or download from The Central Repository:

Option 1: Build a *.jar file locally from the GitHub Repo

  • Clone this repo and cd to the cloned directory location
  • Build the plugin with mvn clean package
  • There should now be a nexus-repository-r-1.1.0.jar file your <cloned_repo>/target directory

Option 2: Download a *.jar file from The Central Repository

Once you've completed Option 1 or 2, copy the nexus-repository-r-1.1.0.jar file into the <nexus_dir>/deploy folder for your Nexus Repository installation.

Restart Nexus Repo, or go ahead and start it if it wasn't running to begin with.

You should see the R repository types (e.g. r (proxy)) in the available Repository Recipes to use if everything goes according to the plan.

The Fine Print

Starting from version 3.20+ the R plugin is supported by Sonatype, but still is a contribution of ours to the open source community (read: you!)

Phew, that was easier than I thought. Last but not least of all:

Have fun creating and using this plugin and the Nexus platform, we are glad to have you here!
