Howto deploy plugins to 1.3.6

[Steffen Stundzig]

Hi,

I've installed and package the sample kungfu repository customizer. Now
I need to deploy them to nexus. But how can I do that?

Blog and Wiki and Nabble say's

copy the bundle zip to <nexus>/plugin-repository, unzip it und restart nexus

So I've added a hosted repository named plugin-repository and unzipped
the bundle.zip into it and also restarted my nexus.

But the virusscanner isn't loaded. I added some System.err.println into
the virusscanner-classes to track it. ;)

What must I do?

And finally I've tried the same with nexus 1.4.0-SNAPSHOT, with same
results.

Next I analysed the generated META-INF/nexus/plugin.xml from the bundle.
It looks like:

<?xml version="1.0" encoding="UTF-8"?>
<plugin>
  <modelVersion>1.0.0</modelVersion>
  <groupId>org.sonatype.nexus.plugins.samples</groupId>
  <artifactId>nexus-kungfu-virusscanner-plugin</artifactId>
  <version>1.0.0-SNAPSHOT</version>
  <name>Nexus Sample Plugins :: KungFu VirusScanner</name>

<pluginSite>http://www.sonatype.com/people/2009/06/writing-plugins-for-nexus-part-1/</pluginSite>
  <applicationId>nexus</applicationId>
  <applicationEdition>OSS</applicationEdition>
  <applicationMinVersion>1.4.0</applicationMinVersion>
</plugin>


but should them also contain some components like in
https://docs.sonatype.com/display/NX/Nexus+Plugin+Packaging

I've generated the plugin.xml with mvn package. Maven is version 2.2.1.

This will only work with 1.4+. The plugin repository is a folder in
sonatype-work/nexus/plugin-repository...so not a repo in nexus in the
traditional sense, although that raises some interesting
possibilities.

thanks brian,

if it were a repo unzipping uploaded plugins with e repo customizer
plugin would be a simple installation mechanism?

And the missing components section in the generated plugin.xml? Is it a
problem or scans nexus the plugin.jar itself for the named annotation?

regards

Stefan, this is really cool what you did here!

But you can go one step further:

Look at the PM API:

http://scm.sonatype.org/showfile.svn?path=/trunk/nexus/nexus-plugins/nexus-plugin-manager/src/main/java/org/sonatype/nexus/plugins/NexusPluginManager.java&revision=HEAD&name=Nexus

nexusPluginManager.installBundle(File file);

;)

Also, alternative path would be to invoke activatePlugin (since you already installed it, but the above is the preferred way to go).

Sorry,

the input parameter is the ZIP File (so, not the unpacked dir).
