At the time. SWY was at version 3.7.2 and the downloaded file was swt-3.7.2-gtk-linux-x86_64.zip.
Make a temporary folder to unzip the files to:
Unzip the contents to the temporary folder:
unzip swt-3.7.2-gtk-linux-x86_64.zip -d swt
where -d swt is the directory to unzip to.
copy the swt.jar file to the Vuze directory. For example if vuze was downloaded to the home directory the command would be:
cp -f ~/swt/swt.java ~/vuze/
An alternative but easier solution is to install vuze is to use the repository version isn’t necessary the same version as the one on the website:
sudo apt-get install Vuze
