Unable to find plugins in list of available plugins in jenkins

Question

I have installed Jenkins by deploying its WAR file to Tomcat. On typing

http://localhost:8080/jenkins

In browser, jenkins home page is opening which means jenkins is successfully installed. I configured system settings, gave jdk and maven path and save them. Then to install plugins, I clicked on Jenkins->Manage plugins and clicked on Available tab but could not find any plugins. I tried three solutions:

1. Configured proxy for Jenkins by going to Jenkins->Manage Plugins->Advanced(did not find plugins)

2. Restarted server, refreshed browser and went to Jenkins->Manage plugins->Available (still did not find any plugins). So, I read somewhere that we have update plugins forcefully if they are not updated automatically. So, went to Jenkins->Manage Plugins->Advanced and clicked the tab 'Check now' (Still did not find any plugins on clicking on Available tab).

3. Finally I read somewhere that if we add the pluginGroup 'org.jvnet.hudson.tools' to settings.xml file of maven, problem may be resolved. So, added the corresponding code to settings.xml:

Then I tried again but still could not find any plugins in

Jenkins->Manage plugins->Available

If any other solution is there which can resolve this problem please let me know.

Answer 1

Go to: Manage Jenkins → Manage Plugins → Advanced, then click Check now in the bottom right-hand corner. When you go back to Available tab all plugins should be listed.

Answer 2

At the plugins section of Jenkins open the "Advanced Settings" tab and paste the following URL into the Update Server URL field (at the bottom): https://updates.jenkins.io/update-center.json

Answer 3

For me the following worked:

Go to Manage Jenkins->Configure Global Security

Click the checkbox for "Use browser for metadata download"

I also have security disabled and prevent cross site forgery unchecked.
