Figure 12.4. Windows 10 Firewall
CloverETL Designer application starts as two processes: CloverETL Designer GUI and CloverETL Runtime. These processes need to communicate with each other over TCP protocol. You should allow the mutual communication with Allow access button.
Linux
Designer Crashes due to Issue in Eclipse on Linux
Eclipse 3.8, 4.2 and 4.3 using some versions of WebKitGTK+ crashes.
As a workaround, the following line can be added to the end of the eclipse.ini:
-Dorg.eclipse.swt.browser.DefaultType=mozilla
See Eclipse bug tracker https://bugs.eclipse.org/bugs/show_bug.cgi?id=404776.
Designer Stops Responding
Due to bug in Linux/GTK+, Designer runs out of number of open files
as the backend opens the file /etc/cups/client.cont many times.
As workaround, you can configure the printers in /etc/cups/client.conf file, or add -Dorg.eclipse.swt.internal.gtk.disablePrinting to CloverETL.ini file.

or https://bugzilla.gnome.org/show_bug.cgi?id=346903.
Welcome Page not Displayed on Linux
Welcome page requires webkitgtk library to be present on your system.
Install webkitgtk version 1.
Hints on Edges Have no Content on Linux
If hints on edges contain only the frame but no content,
you should install webkitgtk.
Others
Subclipse
If you use CloverETL Designer with Subclipse plugin,
and perform the following steps:
In a project, create a directory aaa,
create a file bbb,
delete the directory aaa,
and rename file bbb to aaa;
you may encounter the message:
An exception has been caught while processing the refactoring 'Rename resource'. Reason: Problems encountered while moving resources. Error deleting markers for resource bbb. Resource aaa does not exist.
This problem is caused by caching resources by the Subclipse plugin an has nothing to do with CloverETL.
If this message appears, refresh the project in Navigator.
