How to release a new plugin version?

[Jan Niklas Hasse]

Hi!

I'm trying to release a new version of the python-plugin (https://github.com/jenkinsci/python-plugin). I couldn't find a guide for this and also my Java / Maven skills are pretty low. My guess is, that I need to run

mvn release:prepare

but this gives me (after a lot of Downloading) the following errors:

[INFO] Verifying that there are no local modifications...

It looks to me that some dependencies changed their names, but I'm pretty clueless how to fix this. Can someone help me out?

Hmm, it seems that it's looking in maven central for the hpi-plugin when it should be looking in repo.jenkins-ci.org/public

Have you configured your maven settings as described here? https://wiki.jenkins-ci.org/display/JENKINS/Plugin+tutorial#Plugintutorial-SettingUpEnvironment

I don't know if it will be useful but i use this command to update the version of my plugin:

mvn versions:set versions:commit -DnewVersion={You number version}

mvn package

(mvn install)

Hi

org.apache.maven.plugins:maven-release-plugin:2.0-beta-9:prepare is a really too old version of the maven release plugin

For sure it is failing for a git incompatibility issue or something like this.

If you want to release without changing in your project you should use

mvn org.apache.maven.plugins:maven-release-plugin:2.5.1:prepare org.apache.maven.plugins:maven-release-plugin:2.5.1:perform

Otherwise you should consider to enforce the version of this plugin in your pluginManagement section

Jim, from my POV, it is really better/safe to correctly configure the release plugin to be sure to have a coherent build and tags.

No I haven't, thanks! Now I'm running into:

[INFO] WARNUNG: Error injecting: org.jenkinsci.maven.plugins.hpi.AptCompiler
[INFO] java.lang.NoClassDefFoundError: com/sun/mirror/apt/AnnotationProcessorFactory

Which might be because I'm still on Ubuntu 14.04?

[Vincent Latombe]

It's probably failing because the plugin depends from a very old core version which doesn't support jdk 8, and you are using a jdk 8 to build the project.

Either :

- install a jdk 7

- update the parent version to something more recent (such as 1.565.1, one year old, but should work better than the current 1.409)

I agree.

Thanks! I updated to 1.565.1 and now it works.

Unfortunately `mvn release:prepare` didn't set the version to 1.3, but left 1.3-SNAPSHOT: https://github.com/jenkinsci/python-plugin/blob/python-1.3/pom.xml
The other tags don't have -SNAPSHOT in them: https://github.com/jenkinsci/python-plugin/blob/python-1.1/pom.xml

Is this bad? Can I fix it?

The plugin hasn't actually been released to the update center, snapshots are ignored.

It's the first item here: https://wiki.jenkins-ci.org/display/JENKINS/Hosting+Plugins#HostingPlugins-Workingaroundcommonissues

Thanks! Now it works. Sorry I didn't RTFM ;)
