The error can be fixed by running the following commands:
We should add a mechanism in Apabe SIS command-line and JavaFX applications for offering to download those dependencies automatically when first required.
The combined size of above dependencies is about 1 Mb. It is not very big, so we could have included those dependencies in SIS binary distribution. But the same mechanism could be applied to UCAR netCDF and to Amazon SDK dependencies too, which are much bigger.
