Documentation for Crucible 3.0.x. Documentation for other versions is available too.

This page shows the supported platforms for Crucible 3.0.x and its minor releases.

Key: (tick) = Supported; (error) = Not Supported

Java Version




(tick) 1.6
(tick) 1.7

Crucible requires Java Runtime (JDK or JRE), version as noted. Pre-release/Early access versions of the Java Runtime are not supported.

You can download a Java Runtime for Windows/Linux/Solaris. On Mac OS X, the JDK is bundled with the operating system.

We highly recommend that you use the Oracle JVM (or use the default Mac OS X JVM), as other implementations have not been tested.

Please note:

  • Once you have installed the JDK, you need to set the JAVA_HOME environment variable. See Installing Crucible on Windows or Installing Crucible on Linux and Mac for details.
  • If you are using a 64-bit JVM, please ensure that you've set your max heap size (--Xmx) to a reasonable value, considering the RAM requirements of your system.
Operating Systems



Microsoft Windows


  • Crucible is a pure Java application and should run on any platform provided the requirements for the JRE or JDK are satisfied.
  • (warning) Although Crucible can be run in virtualised environments, Atlassian is not yet able to provide technical support for performance-related problems in a virtualised environment. If you do chose to run Crucible in a VM, please ensure that you choose a VM with good IO throughput.



Apple Mac OS X






(tick) MySQL Enterprise Server 5.x
(tick) MySQL Community Server 5.x

Crucible supports a number of external databases, as listed. See the Crucible Database documentation for further details.

(warning) For MySQL:

  • For 5.0, version must be 5.0.21 or later
  • For 5.1, version must be 5.1.10 or later
  • For 5.6, version must be 5.6.11 or later.


(tick) 8.2, 8.3, 8.4


(tick) 11g

SQL Server

(tick) 2005, 2008, 2008 R2

HSQLDB ( 3 )

(tick) Bundled; for evaluation use only

The Crucible built-in database, running HSQLDB, is somewhat susceptible to data loss during system crashes.

We recommend that you do not use HSQLDB for production systems.

External databases are generally more resistant to data loss during a system crash and are more suited for production use.

Deployment Notes for Source Code Repositories

Crucible can also store uploaded files in its own database, removing the need for any kind of repository. A number of external databases are supported when Crucible is used with FishEye. See the FishEye Supported Platforms.
