What are the nightly builds?

The nightly builds are interim builds that are untested and unsupported. Use at your own risk!
These unreleased builds may not even load, may have undocumented features, known defects, and any number of other issues.
They are intended for use by developers and others wishing to help with resolving JMeter bugs.

These builds should not be used in production.

Installing JMeter runtime

Download the _bin and _lib files
Unpack the archives into the same directory structure
The other archives are not needed to run JMeter.

Building JMeter

Download the _src, _bin and _lib files
Unpack all the archives into the same directory structure

Warning - please note!

The nightly builds may or may not work properly - or at all.

If there is a problem with a particular version, it may be worth reporting this on the JMeter-dev mailing list and/or trying again in a day or two.
