問題

Some functionality, which are provided by the bundled plugins stored in atlassian-bundled-plugins.zip cease to work. For example:

1. Confluence Dashboard renders unknown macro in place of the recently-updated section.
2. Graphical user interface, for example the pull down menu no longer works.
3. Index rebuild does not work.
4. Dashboard does not render, throwing a browser redirection error.

診断

The following stack trace appears in the atlassian-confluence.log:

2009-06-25 15:49:49,243 ERROR [main] [atlassian.plugin.util.FileUtils] conditionallyExtractZipFile Found file:/apps/confluence-3.0.0_01/confluence/WEB-INF/classes/com/atlassian/confluence/setup/atlassian-bundled-plugins.zip, but failed to read file
java.io.IOException: Unable to delete file: /apps/data/confluence-data/bundled-plugins/toc-plugin-2.4.5.jar
	at org.apache.commons.io.FileUtils.forceDelete(FileUtils.java:1390)

原因

This is usually due to Confluence inability to update the bundled plugins in the Confluence home folder. Usually related to write permissions. For example if the files belong to root user account and Confluence is run by a non-root user account, then it may not be able to delete (ie. update) its bundled plugins.

ソリューション

Check for your files and/or folder permissions in <confluence home>/bundled-plugins folder. Make sure that Confluence is run by a user with sufficient write permission.
