Update JMeter plugins from CLI in CI/CD

Following the request of one of our users, we would like to share with you the procedure to update JMeter plugins from the command line interface (CLI) in a continuous integration and delivery pipelines.

The context

When deploying JMeter within a CI/CD pipeline you want to:

• Install a plugin automatically
• Update the plugin automatically to the latest version

In this blog we’ll see how JMeter-Plugins-Manager can help updating plugins using CLI in CI/CD pipelines.

The Pre-requisites

• Download https://jmeter-plugins.org/get/ and put it in jmeter/lib/ext
• Make sure cmdrunner-X.Y.Z.jar is present in jmeter/lib directory
• If not, take it from here, the latest version is 2.3 at the time of the writing (https://repo1.maven.org/maven2/kg/apc/cmdrunner/2.3/cmdrunner-2.3.jar)
• Start JMeter then quit, this will install additional files, make sure PluginsManagerCMD.sh or PluginsManagerCMD.bat is present in jmeter/bin directory
• If not, from jmeter/bin folder, run below command to have the files created:

java -cp jmeter/lib/ext/jmeter-plugins-manager-1.7.jar org.jmeterplugins.repository.PluginManagerCMDInstaller 

The solution to update JMeter Plugins using CLI in CI/CD pipelines

Now we have the setup done, we will test using UbikLoadPack Video Streaming plugin, but you can do it with any JMeter-Plugin that is published at https://jmeter-plugins.org.

To see if there are updates:

./PluginsManagerCMD.sh upgrades  ulp-jmeter-videostreaming-plugin

If there are updates you’ll get the following output:

There are updates (8.0.0 is installed):
2021-11-09 16:08:07,764 INFO o.j.r.PluginManagerCMD: Command is: upgrades

[ulp-jmeter-videostreaming-plugin=8.0.1]

If there are NO updates you’ll get the following output (if 8.0.1 is installed):

2021-11-09 16:16:46,372 INFO o.j.r.PluginManagerCMD: Command is: upgrades

There is nothing to update.
