Problem: Eclipse fails to start, with message –
java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: no swt-gtk-3740 in java.library.path no swt-gtk in java.library.path
Reason: Tries to find these libraries in the corresponding location for OpenJDK.
In terminal,sudo gedit/etc/eclipse.ini
Append line (VM args section being last): -Djava.library.path=/usr/lib/jni
Save close the file.
Eclipse should launch successfully now.
