Failed to load Plugins Manager net.sf.json.JSONException: Invalid JSON String

[dssh...@gmail.com]

I am using a newly installed JMeter 3.0 without any modifications other than adding jmeter-plugins-manager-0.8.jar into \lib\ext. I get the following in the JMeter.log file and the JMeter Options menu has no mention of the plugin manager. I did add log_level.org.jmeterplugins.repository=DEBUG before generating this log. Java version is 1.8.0_60.

Any suggestions?

Thanks.

Hi,

Can't it be the corporate firewall blocking?

Can you open http://jmeter-plugins.org/repo/ in your browser and see JSON there?

Thank you. I added proxy information to the command line options and it is working.

Cheers,
