exception: java.lang.NoSuchMethodError: gitbucket.core.util.JGitUtil$.getFileList

[zsmahi]

Hello the Team

I'm new in gitbucket and explorer plugin. I've installed it this morning as explained in the readme file however the explorer tree is empty (see image below), and when expecting the code I've found that the issue was caused by an internal error 500 (an exception was thrown) the details of this exception is java.lang.NoSuchMethodError: gitbucket.core.util.JGitUtil$.getFileList

I use windows 10, tomcat 9 and gitbucket version 4.34.0

can you help me to solve this ? thanks in advance.

Here is the screenshot

and the trace of the exception

[takezoe]

Thanks for reporting! There is a binary incompatibility in GitBucket 4.43.0. We need to update this plugin.

[zsmahi]

@takezoe thanks for your answer, so is the fix a priority or should I wait a moment until it'll be fixed ?

Released a fixed version: https://github.com/gitbucket-plugins/gitbucket-explorer-plugin/releases/tag/8.0.0
