I am using the version 7.0.650.20 of JAVA.
Does anyone have an idea why I could not open my file ?

Answer 1

You're using Third Party jmeter-plugins.org plugins.
You need to add the required jar in lib/ext so that it works.
Download plugins-manager.jar from here and put it into lib/ext directory, then restart JMeter.
Note you need to do it each time you upgrade your jmeter version !

Answer 2

Download plugins-manager.jar and put it into lib/ext directory, then restart JMeter.

Answer 3

I am using JMeter 3.3 and answers above did not work for me.
SOLUTION:
Download plugins-manager.jar from https://jmeter-plugins.org/downloads/all/
Put plugins-manager.jar into jmeter/lib/ext
Restart jmeter
Open script, it will ask to download dependencies, press yes.

Answer 4

1)Download standard JMeterPlugins-Standard-1.4.0.zip from http://jmeter-plugins.org/#/
2)Extract it and go inside extracted folder /lib/ext.
4)Copy JMeterPlugins-Standard.jar and CMDRunner.jar from /lib/ext to Jmeter/lib/ext

Answer 5

For people who are using command line for running JMeter, here is how to install a new plugin.
After placing the plugin manager jar in the /lib/ext/, download the latest cmdrunner from this URL by changing the version.
wget http://search.maven.org/remotecontent?filepath=kg/apc/cmdrunner/2.2/cmdrunner-2.2.jar
Copy the cmdrunner to jmeter/lib/ directory
mv cmdrunner-2.2.jar apache-jmeter-5.1.1/lib/
Execute the following command to generate script file PluginsManagerCMD
java -cp apache-jmeter-5.1.1/lib/ext/jmeter-plugins-manager-1.3.jar org.jmeterplugins.repository.PluginManagerCMDInstaller
After the script is generated, you can use it to install a particular plugin
apache-jmeter-5.1.1/bin/PluginsManagerCMD.sh status
apache-jmeter-5.1.1/bin/PluginsManagerCMD.sh available
apache-jmeter-5.1.1/bin/PluginsManagerCMD.sh install jpgc-tst=2.5

Answer 6

download jar files from https://jmeter-plugins.org/downloads/file/JMeterPlugins-Standard-1.4.0.zip
extract and copy lib/etx/*.jar to jmeter/lib/etx/

Answer 7

Make sure you have the proxy server configured if you are behind one.
I had plugins-manager.jar in lib\ext, but it only worked once I added the proxy to bin\system.properties:
http.proxyHost=my.proxy.server
https.proxyHost=my.proxy.server
http.proxyPort=8080
https.proxyPort=8080
Or:
jmeter -H my.proxy.server -P 8000 -u username -a password
