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 a binary archive (i.e. one without a _src suffix) and unpack it

Building JMeter

Download a source archive (i.e. one with a _src suffix) and unpack it
Run ant download_jars from the top-level directory to fetch the dependencies.

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.
