Install Universal Wiki Converter -> NoClassDefFoundError

I wanted to install the latest version of the UWC, but got following error:

/opt/atlassian/confluence/uwc # ./run_uwc_devel.sh
Exception in thread "main" java.lang.NoClassDefFoundError: com/atlassian/uwc/ui/UWCForm3
Caused by: java.lang.ClassNotFoundException: com.atlassian.uwc.ui.UWCForm3

at java.lang.ClassLoader.loadClass(ClassLoader.java:268)
Could not find the main class: com.atlassian.uwc.ui.UWCForm3. Program will exit.

The documentation on https://migrations.atlassian.net/wiki/pages/viewpage.action?pageId=1015819#UWCF.A.Q.-I%27mgettingaNoClassDefFoundErrorwhenIruntheUWC,howcanIfixthis? refers to a UWC Forum, but the link doesn't exist.

Does someone have a solution for this?

We are using Confluence 5.4.4.

Werner, seems the Confluence version you are running is not compatible with the plugin (Confluence Server 4.0 - 4.3.7)

Please refer:

Hope it helps!

Cheers

Hi Darren, we didn't start to use the UWC.
