After attempting to upgrade Bamboo using the Windows installer, the process tops and nothing is written to the $BAMBOO_HOME\logs\atlassian-bamboo.log file. An error: "More than one fragment with the name [spring_web] was found."  is logged to the  $BAMBOO_INSTALL\logs\catalina* files


  • Windows using the installer MSI


Inspecting the $BAMBOO_INSTALL\logs\catalina*  files show the below error:

When executing a rolling upgrade of Bamboo using the windows installer to the same installation folder as the previous installation, old files can fail to be cleaned up causing duplicate libraries of different versions to be present on the classpath.


This method involves removing all Bamboo installation files related files from $BAMBOO_INSTALL and starting from a fresh directory. If you are unclear on the difference between your Bamboo install and Bamboo home directory, it may be beneficial to read the documentation as it's very important that the Bamboo home directory is not removed:

  1. Please ensure you backup any configuration files within the installation folder such as $BAMBOO_INSTALL\conf\server.xml or $BAMBOO_INSTALL\bin\setenv.bat that may have customizations applied.
  2. Uninstall the Bamboo installation files/binaries.
    • (warning) Be sure to keep your $BAMBOO_HOME directory as it contains state / your data which is needed for an upgrade.
  3. Ensure there are no binary files left within $BAMBOO_INSTALL 
  4. Reinstall Bamboo binaries using the installer.

Alternatively, you could reinstall to a completely separate directory rather than re-using the old one.
