Hi Mark,
I have made the change on the import and also the following line and the
build is fine.
/*params.put("Authorization", "Basic " +
Base64.encode(authString.getBytes()));*/
params.put("Authorization", "Basic " +
Base64.getEncoder().encodeToString(authString.getBytes()));
When I run dspace/bin/dspace filter-media I get the following...
The script has started
