Bamboo fails to start up and the following error appears in the logs

A license key which was used has invalid format and could not be parsed by Bamboo. Most common mistakes are:

  • copy-pasting only part of a license key
  • blank spaces in the beginning or at the end of the license key

Check if the license key used is exactly the same as stated on


If everything else is failing, access the <bamboo-home-directory>/bamboo.cfg.xml file and try enclosing the license inside the following:

<property name="license.string"><![CDATA[yourlicensehere]]></property>

Note that this is not done via the Bamboo UI, you must access the bamboo.cfg.xml file to apply this.

Please make sure that the formatting of the license key matches what is found in your account. This includes whitespaces and line breaks.
