Nexus Repository Conan Format

Huzzah! Conan is now part of Nexus Repository Manager. Version 3.20 includes the Conan plugin by default. The plugin source code is now in nexus-public in nexus-repository-conan.

Filing issues: Upgrade to the latest version of Nexus Repository Manager 3, to get the latest fixes and improvements, before filing any issues or feature requests at https://issues.sonatype.org/.

Upgrading: If you are using a version prior to 3.20 and upgrade to a newer version you will not be able to install the community plugin. No other changes are required and your existing data will remain intact.

Contribution Guidelines

Go read our contribution guidelines to get a bit more familiar with how we would like things to flow.

Requirements

• Apache Maven 3.3.3+
• OpenJDK 8
• Network access to https://repository.sonatype.org/content/groups/sonatype-public-grid

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

Building

To build the project and generate the bundle use Maven

mvn clean install

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

Using Conan with Nexus Repository Manager 3

We have detailed instructions on how to get started here!

Compatibility with Nexus Repository Manager 3 Versions

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

Plugin Version	Nexus Repository Manager Version
v0.0.1	<3.11.0
v0.0.2 - v0.0.6	>=3.11.0
v1.0.0 In product	>=3.22.0

Installing the plugin

In Nexus Repository Manager 3.22+ Conan proxy is already included, so there is no need to install it. But if you want to reinstall the plugin with your improvements then the following instructions will be useful. Note: Using an unofficial version of the plugin is not supported by the Sonatype Support team. Conan hosted repository is not supported and disabled by default. You can enable hosted repo by setting nexus.conan.hosted.enabled=true in NXRM's properties file.

Permanent Reinstall

• Copy the bundle into: <nexus_dir>/system/org/sonatype/nexus/plugins/nexus-repository-conan/1.0.0/nexus-repository-conan-1.0.0.jar

• Modify xml to introduce the plugin:

  • OSS edition: <nexus_dir>/system/com/sonatype/nexus/assemblies/nexus-oss-feature/3.x.y/nexus-oss-feature-3.x.y-features.xml

  • PRO edition: <nexus_dir>/system/com/sonatype/nexus/assemblies/nexus-pro-feature/3.x.y/nexus-pro-feature-3.x.y-features.xml

        <feature version="3.x.y.xy" prerequisite="false" dependency="false">nexus-repository-rubygems</feature>
        <feature version="1.0.0" prerequisite="false" dependency="false">nexus-repository-conan</feature>
        <feature version="3.x.y.xy" prerequisite="false" dependency="false">nexus-repository-yum</feature>
    </features>
  

  And

      <feature name="nexus-repository-conan" description="org.sonatype.nexus.plugins:nexus-repository-conan" version="1.0.0">
       <details>org.sonatype.nexus.plugins:nexus-repository-conan</details>
       <bundle>mvn:org.sonatype.nexus.plugins/nexus-repository-conan/1.1.0</bundle>
      </feature>
   </features>
  

Installing the plugin in old versions

For older versions there are a range of options for installing the Conan plugin. You'll need to build it first, and then install the plugin with one of the options shown below:

Easiest Install

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 conan plugin, follow these steps:

• Build the plugin with mvn clean package -PbuildKar
• Copy the nexus-repository-conan-0.0.6-bundle.kar file from your target folder to the deploy folder for your Nexus Repository installation.

Once you've done this, go ahead and either restart Nexus Repo, or go ahead and start it if it wasn't running to begin with.

You should see conan (hosted) and conan (proxy) in the available Repository Recipes to use, if all has gone according to plan :)

Temporary Install

Installations done via the Karaf console will be wiped out with every restart of Nexus Repository. This is a good installation path if you are just testing or doing development on the plugin.

• Enable NXRM's console: edit <nexus_dir>/bin/nexus.vmoptions and change karaf.startLocalConsole to true.

  More details here: https://help.sonatype.com/display/NXRM3/Bundle+Development+Overview

• Run NXRM's console:

  # sudo su - nexus
  $ cd <nexus_dir>/bin
  $ ./nexus run
  > bundle:install file:///tmp/nexus-repository-conan-0.0.6.jar
  > bundle:list
  

  (look for org.sonatype.nexus.plugins:nexus-repository-conan ID, should be the last one)

  > bundle:start <org.sonatype.nexus.plugins:nexus-repository-conan ID>
  

Permanent Install

For more permanent installs of the nexus-repository-conan plugin, follow these instructions:

• Copy the bundle (nexus-repository-conan-0.0.6.jar) into <nexus_dir>/deploy

This will cause the plugin to be loaded with each restart of Nexus Repository. As well, this folder is monitored by Nexus Repository and the plugin should load within 60 seconds of being copied there if Nexus Repository is running. You will still need to start the bundle using the karaf commands mentioned in the temporary install.

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

The Fine Print

Starting from version 3.22 the Conan plugin is supported by Sonatype, but still is a contribution of ours to the open source community (read: you!).

Remember:

• Use this contribution at the risk tolerance that you have
• Do NOT file Sonatype support tickets related to Conan support
• DO file issues here on GitHub, so that the community can pitch in

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!
