Configuration file seems OK:

'1.1' encoding='UTF-8'?>
"github@​1.43.0">
  
    
      GitHub Flexi
      https://api.github.com
      true
      fae05251-b00d-40cf-8e7b-1a123d7ce9b9
      20
    
  
 

The same configuration file is recreated when the old one is removed.

 

After every restart, it is necessary to configure GitHub server again, and everything then works as expected.

Configuration file seems OK:

<?xml version='1.1' encoding='UTF-8'?>
<github-plugin-configuration plugin="github@1.43.0">
  <configs>
    <github-server-config>
      <name>GitHub Flexi</name>
      <apiUrl>https://api.github.com</apiUrl>

      <clientCacheSize>20</clientCacheSize>
    </github-server-config>
  </configs>
</github-plugin-configuration> 

The same configuration file is recreated when the old one is removed.
 
After every restart, it is necessary to configure GitHub server again, and everything then works as expected.

  Hi lanwen 
  
  
  
  here is my analysis:
  
  upon saving the github servers information from jenkins UI, it creates/updates a file /var/jenkins_home/github-plugin-configuration.xml and the contents are
  
  <github-plugin-configuration plugin="github@1.44.0">
  
    <configs>
  
      <github-server-config>…
  
      </github-server-config>
  
    </configs>
  
  </github-plugin-configuration>
  
   
  
  github-plugin-configuration and github-server-config are alias/shortcuts that must be explicitly registered with XStream that maps XML elements to java classes. for example:
  
  xstream.alias("github-plugin-configuration", GitHubPluginConfig.class);
  
  xstream.alias("github-server-config", GitHubServerConfig.class);
  
  it seems one of the aliases “github-plugin-configuration” is not registered with XStream.
  
   
  
  i can verify it by providing full class name and there will be no error upon jenkins restart, and we can see the github server information jenkins UI.
  
  <org.jenkinsci.plugins.github.config.GitHubPluginConfig plugin="github@1.44.0">
  
    <configs>
  
      <github-server-config>…
  
      </github-server-config>
  
    </configs>
  
  </org.jenkinsci.plugins.github.config.GitHubPluginConfig>
  
   
  
  However, when we click on apply/save in jenkins configure -> system UI, the plugin will override full class name by alias again as expected.
  
   
  
  Root Cause & Possible Solution:
  
  By inspecting into the Github Plugin, GitHubPluginConfig constructor only registers alias for "github-server-config"
  
  but not for "github-plugin-configuration", causing deserialization failures.
  
  The line already exists: this.getConfigFile().getXStream().alias("github-server-config", GitHubServerConfig.class);
  
  The line that I think is missing: getConfigFile().getXStream().alias(getId(), GitHubPluginConfig.class);
  
   
  
  Possible fix! -> PR # register alias github-plugin-configuration #430
  

Hi lanwen

xstream.alias("github-plugin-configuration", GitHubPluginConfig.class);

xstream.alias("github-server-config", GitHubServerConfig.class);

it seems one of the aliases “github-plugin-configuration” is not registered with XStream.

 

i can verify it by providing full class name and there will be no error upon jenkins restart, and we can see the github server information jenkins UI.
