Adding the Toolbox to a standard Eclipse installation will most likely
not work because of how the Toolbox is implemented.
This is how to install EGit into the Toolbox version 1.7.1:
1) Close the Toolbox
2) In the Toolbox directory:
./toolbox -nosplash -application org.eclipse.equinox.p2.director
-repository
https://download.eclipse.org/releases/2020-06/202006171000
-installIU org.eclipse.egit.feature.group -roaming
3) Launch the Toolbox like you would normally do
4) Open "Find Action" by pressing Ctrl+3 and type "git" to access the
EGit views
Note that this does *not* work if your Toolbox on Linux has been
installed from the .deb file.
