We upgraded Jenkins from v1.502 to v1.504 at the same time as upgrading the plugin. Everything was fine with v1.502 so it is a very recent issue.

We will try downgrading Jenkins and see if that works with v1.10 of the plugin.

[EDIT] Downgrade to Jenkins v1.502 worked. Still using v1.10 of the plugin.

@bap thanks for responding. I'll try v1.10.

Maybe the recent upgrade in jenkins core to xstream 1.4.4 is the culprit?

https://issues.jenkins-ci.org/browse/JENKINS-12542

I'm wondering how this issue is not In Progress. Kinda disturbing regression, guys!

I have resolved the problem for Publish-Over-FTP (I'm sure, the solution for Publish-Over-SSH is the same).
You have to override the method readResolve() in all inherited classes, for Publish-Over-FTP this are:

• BapFtpHostConfiguration
• BapFtpPublisherPlugin$Descriptor

The reason is, that the reflection-mechanism looks for the method readResolve() in the inherited class (see above) and after this in the base-class. The reflection-invoke of the method fails, if the method is declared in the base-class and call over the derived class.
Can I check in the patched classes on GitHub?

The patched sources for resolving the bug...

I can not commit to GitHub, so we have to wait on "bap"...
I use my own patched version successful in my Jenkins 1.510

I tried patching both the SSH and FTP plugins with the readResolve override and running 1.510. I saw a bunch of CannotResolveClassExceptions and the plugin did not load its configuration.

com.thoughtworks.xstream.mapper.CannotResolveClassException: jenkins.plugins.publish_over_ssh.BapSshPublisherPlugin
...

Here's the patch I used, which is the patch @afischer attached: https://github.com/jenkinsci/publish-over-ssh-plugin/pull/3

It's possible that I didn't correctly package the plugin, though.

I have patched and tested only the publish-over-ftp. But I also modified the pom-files for building against the Jenkins API (not anymore the Hudson-API). I can attach the modified pom for the Maven-build.
Can I create my own GitHub-repository and publish the patched plugin (sources, pom, ...) until bap has checked and merged my modifications? I will also patch publish-over-ssh and check again.

I have added a complete patched version of the plugins "publish-over" (base) and "publish-over-ssh" on GitHub:

• https://github.com/afischer211/publish-over-plugin
• https://github.com/afischer211/publish-over-ssh-plugin

Can you test it?

Thanks for looking int this Alex,

Unfortunately I am still unable to reproduce this issue - and I have tried upgrading from many versions of the plugins at the same time as upgrading Jenkins to 1.504 accross all of cifs, ftp and ssh. I suspect that the problem is JVM version specific.

I'd like to identify exactly where the problem lies, and and only fix there (i.e I do not really want to pull the minimum required version of jenkins to a version that is even newer than the current LTC RC)

The issue could potentially be solved with a calculated serialVerUID - a readResolve method is not supposed to concern itself with any sub or supertypes (so another possible fix may be to return "this" from readResolve in the serialized class definition)

I will be able to dedicate a large amount of time to this issue following this weekend.

Can everyone with this problem please provide their os, version including architecture and the full details of the JVM that the jenkins master is using?

I have the same issue if I upgrade Jenkins from 1.502 to the latest version.

Publish Over SSH
1.10

Just updated to Jenkins ver 1.513. Then went to re-add the Publish over SSH sites like I typically do after a Jenkins restart. I was a bit surprised to find the SSH information still present. All I had done was update to Jenkins 1.513, update the Maven and ScriptTrigger plugins. Suspect that something in the new Jenkins eliminates this issue?

Still KO for us with 1.513 (same Jenkins instance than Maxime Ménard).

Any word on official fix for this?

Alexander Fischers github versions worked for us.

Perhaps the support for older versions of Jenkins / Hudson could/should be sacrificed?

Thank You!

This continues to be a painful issue. Are the code fixes mentioned in the thread not candidates for release?

We have the same problem (SSH sites configuration and credentials disappear upon Jenkins restart).
Windows Server 2008R2
JVM: 1.7.0_21-b11
Jenkins: 1.509.2 (LTS)
publish-over-ssh: 1.10
ssh-credentials: 0.4

I had exactly this problem as well.
I tried downgrading the plugin to 1.9, which didn't help.
Then I tried upgrading from 1.509.2 LTS to 1.524 latest, and that didn't help.
Then I downgraded back to 1.509.2 LTS w/ the 1.9 plugin, and that seems to be ok now...

Same Problem:

• Jenkins ver. 1.525 (Release: 1.1, Buildtime: Mon Jul 29 20:49:41 2013)
• PlugIn-Versions 1.7 and 1.10
• OS: CentOS release 6.2
• JVM: java version "1.7.0_25" OpenJDK Runtime Environment (rhel-2.3.10.4.el6_4-i386)
• Jenkins installed and updated by "YUM"; Repo: http://pkg.jenkins-ci.org/redhat/

Looks like Class-Loader-Issue.

If you cannot reproduce it, maybe it is related to: Other Plugin; Ancient un-Migrated config-XML; Classloader-isolation issues of the runtime-Container

If it helps with reproducing the issue, I've started using Jenkins from version 1.520 so the configs were newly created. No older configs were present. Only thing that may be older than this version was a sample php project from jenkins-php.org which doesn't use the publish over ssh plugin.

Still stucked on 1.502 due to this issue (last tested against 1.526).

Note that "Publish over FTP" config does work for us.

To summarize JVM on previous comments:

• 6u20 (32b?)
• 6u24 (64b?)
• 6u26 (64b)
• 6u27 (64b)
• 6u33b3 (64b)
• 7u5 (64b)
• 7u9 (64b?)
• 7u21 (? )
• 7u25 (32b?)

This bug is on Linux (RH-based and Debian based), Windows (2008 server, Vista, 7).

@bap is'nt it possible to start from Alexander Fischer's patch? I undestand you want to reproduce it first, but this patch does not seem error-prone.

Is @bap still working on this plugin? We have several folks for whom this has become an persistent nagging issue. What do we need to do to get a functional update checked in and built???

I have retaken Alexander's patch, forking Thomas Van Doren repo that included it. I corrected the build failure (only an artifact version problem), and now it works on our Jenkins installation, updated to 1.527.

It's here: https://github.com/key-consulting/publish-over-ssh-plugin/tree/JENKINS-17058

Could someone build(1) and test it one more time, to be sure?

I will then launch another pull request.

(1) cannot be built with JDK7, given Jenkins API version.

I tested Alexander's patch and it also works in my environment Jenkins 1.527 installation. I used JDK6

Here the pull request: https://github.com/jenkinsci/publish-over-ssh-plugin/pull/4

The Jenkins build has failed, due to the lack of compat with JDK 1.7 I pointed.

I'd like to add that it is now October 15th and it still has not been fixed.

Hello there. I was able to reproduce this bug. It happens when I add at least one server to both publish over ftp & ssh settings, then ssh config can't be read, but ftp is ok. Ssh plugin alone works well. Tested on jenkins 1.533 clean install.

So, if I delete all ftp servers, newly added ssh servers could be loaded after restart.

Hope this info will be helpful, and would be glad if someone could confirm it.

we were using that plugin several months without problems. we were only using the "publish over ssh" plugin. a few days ago we installed the "publish over cifs" plugin and now we are running into that problem! if I disable the "cifs" plugin all is fine! maybe this helps...

@Sylvain Veyrié: I tested your pull request and it works!

I can confirm that when I uninstalled both the publish over FTP and CIFS plugins that is resolved this issue. This is with Jenkins 1.536 on Ubuntu Java 7.

I'm so glad this is In Progress... For so many months I've had to re-enter all my SSH configs after each restart. I know all the paswords by heart now.

Now that we know the way to reproduce this issue is anyone working on a permanent fix?

There does appear to be a pending pull request: JENKINS-17885

Email from bap:

Hi Mark,

I no longer use Jenkins and don't have time to maintain the publish over plugins.

Feel free to merge, test and release as you see fit.

Regards,
Bap.

Compare: https://github.com/jenkinsci/publish-over-ssh-plugin/compare/c591bae51812...dbc15b7ae03b

What do we need to do to get on the maintainers list?

Hello,

I hve fixed the problem earlier this year. See my Jira-comments on April of 2013.
You can look into my sources on Github.

• https://github.com/afischer211/publish-over-plugin
• https://github.com/afischer211/publish-over-ssh-plugin

I don't know, how to propagate my patches to the official version of the plugins (pull-request?). So I use my own patched version since April without any problems until now with Jenkins 1.544.

@Preston, I suggest e-mailing on this thread in the jenkins-dev mailing list: https://groups.google.com/forum/#!topic/jenkinsci-dev/7vEwarVHbgc

Slide merged the change today and is supposed to be pushing out a release, but he's still looking for a new official maintainer.

fix for jenkins-bug #JENKINS-17058

overriding method readResolve() from base-class BPHostConfiguration for
resoving Reflection-problems with XStream

Fixed in version 1.11 of the Publish over SSH plugin.

Hi All, For clarity, can someone please answer this q'n?

We're still on Jenkins 1.509.2 LTS, Windows exe, bundled 1.6 Java RE (like bdellegrazie above) and have this problem.

I am browsing the GitHub forks trying to work out the necessary dependencies to obtain a compatible 'fix' for Publish Over SSH without updating Java RE or Jenkins core.

Will the 'fixed' SSH 1.11 work on 1.509 LTS and J6RE despite the apparent new baseline?

Ref from the MANIFEST.MFs:

Plugin-Version: 1.10
Hudson-Version: 1.388
Build-Jdk: 1.6.0_32
Depends on Publish-Over: 0.17

Plugin-Version: 1.11
Hudson-Version: 1.532.1
Jenkins-Version: 1.532.1
Build-Jdk: 1.7.0_45
Depends on Publish-Over: 0.18

I came in with a similar issue. I installed a brand new Jenkins and brand new set of plugins. I attempted to add a server in the manage jenkins configuration area and the values would disappear over and over again. I am essentially copying another jenkins master to test something. So, I went to the existing jenkins master and copied 

jenkins.plugins.publish_over_ssh.BapSshPublisherPlugin.xml

 from the old master to the new one. The values show up in the dashboard and I can modify it and it works, etc. 

The Jenkins is version 2.104, the plugin is 1.18 The underlying OS is Centos 7.2

Something is preventing Jenkins from creating this file. I don't know what to stack trace. Not a java programmer. I figure I'd throw this out there if you want a workaround.
