JIRA Home Directory

data

This directory contains application data for your JIRA instance, including attachments (for every version of each attachment stored in JIRA).

export

JIRA will place its automated backup archives into this directory.

log

JIRA will place its logs into this directory. (Note: if the JIRA home directory is not configured, then the logs will be placed into the current working directory instead).

The logs will only start showing up once the first log message is written to them. For example, the internal access log will not be created util JIRA starts writing to it.

You can change the location of the log file using log4j.properties as described in the documentation on Logging and Profiling.

plugins

This is the directory where plugins built on Atlassian's Plugin Framework 2 (i.e. 'Plugins 2' plugins) are stored. If you are installing a new 'Plugins 2' plugin, you will need to deploy it into this directory under the installed-plugins sub-directory.

'Plugins 1' plugins should be stored in the JIRA Installation directory.

This directory is created on JIRA startup, if it does not exist already.

caches

This is where JIRA stores caches including:

• Lucene indexes - see Indexing in JIRA
• OSGi framework caches

These files are vital for JIRA performance and should not be modified or removed externally while JIRA is running.

Note:

See Search Indexing for further details.

tmp

Any temporary content created for various runtime functions such as exporting, importing, file upload and indexing is stored under this directory.

You can remove files from this directory while JIRA is running, but we recommend that you shut down JIRA first before altering the contents of this directory.
