要約

Bamboo import fails with EOF exception when importing a Bamboo export file.

E.g.

• Export from old Bamboo Server
• Import to new Bamboo Server

The following error log appears during the import process on the new server.

診断

環境

• Bamboo Server

Diagnostic Steps

• Create an export from an older Bamboo Server
  • Follow the logs under $BAMBOO_HOME/logs/atlassian-bamboo.log  and monitor the export. Look for any exceptions during the export process such as an OutOfMemoryError.
• Attempt to import on a new Bamboo Server 

原因

The exception is caused due to a problem generating the export file from your source instance. The export file may not have completed properly and have missing data.

回避策

• Create a new export from the original server
• Ensure the server has enough memory to complete the export 
  • This can be viewed under the $BAMBOO_HOME/logs/atlassian-bamboo.log on the Bamboo instance that generated the export. If there is not enough memory there will be an OutOfMemoryError  visible in the logging.
• Ensure there are no empty XML files in the export zip file after exporting

ソリューション

• Check your memory usage on the origin Bamboo instance. Make increases in small increments such as an additional 256mb  or 512mb  to the JVM settings in your $BAMBOO_INSTALL/bin/setenv.sh  script. Details found here.
• Ensure there is enough free disk space available on the machine to complete the export which will vary in size depending on which elements you've chosen to include.

• Perform a fresh export and monitor the application logs under $BAMBOO_HOME/logs/atlassian-bamboo.log looking for a successful export job message without any exception such as:
