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

Answer 1

Change the update site from https://updates.jenkins.io/update-center.json to http://updates.jenkins-ci.org/update-center.json

Answer 2

Or your plugin can be already installed. Once it's installed it's not in the list of available plugins.

Answer 3

For those like me who use Jenkins with Docker with a JDK8u60+ version, you need to remove the MD5 hash in JDK_HOME/jre/lib/security/java.security to make it works:

jdk.certpath.disabledAlgorithms=MD2, MD5, RSA keySize < 1024

To

jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024

This should be a temporary workaround

Answer 4

not sure why/how it worked, but after doing below steps, i was able to see the 'available' plugins : 1. Go to Manage Jenkins 2. Click 'Reload Configuration from Disk'. It takes a minute or two to reload jenkins 3. Manage Plugins -> Available.

Answer 5

If you're using Chrome Go to: Manage Jenkins → Manage Plugins → Advanced, then click Check now in the bottom right-hand corner. Then click a shield icon in the address bar, click Load anyway and Jenkins will start to update plugins. In Firefox this icon is situated on the left side of address bar, near back button.

Answer 6

Following steps worked for me for JENKINS VERSION 2.150

• Go to Manage Jenkins->Configure Global Security

• Click the checkbox for "Use browser for metadata download"
