Exception in thread "main" java.lang.NoClassDefFoundError: sdb/sdbconfig

I want to export my ontology (made in Protege) into MySQL database. I was following these instructions: https://jena.apache.org/documentation/sdb/installation.html, and https://jena.apache.org/documentation/sdb/commands.html. And when I use the command "bin/sdbconfig --sdb=sdb.ttl --create", I get this error:

Exception in thread "main" java.lang.NoClassDefFoundError: sdb/sdbconfig

Could not find the main class: sdb.sdbconfig.  Program will exit.

I set the environment variables like this:

Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export SDBROOT="d:/My Dropbox/Diplomska/SDB-1.3.3"

Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export SDB_USER="root"

Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export SDB_PASSWORD=""

Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export SDB_JDBC="d:/Fakultet/jars/mysql-connector-java-5.1.7-bin.jar"

Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export PATH=$SDBROOT/bin:$PATH

This is the output of the command "bin/sdb_path":

Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ bin/sdb_path

And this is the "Store/sdb.ttl" file: @

<#conn> rdf:type sdb:SDBConnection ;

    sdb:sdbName       "SDB" ;
    sdb:driver        "com.mysql.jdbc.Driver" ;
    .

Can anyone tell me what am I doing wrong?

This is a really basic error: sdbconfig's classpath must be wrong. However I don't know windows and cygwin at all.

My guess is that the space in the path 'My Dropbox' is causing this. Could you try moving sdb to another directory? You could also try export SDBROOT="d:/My\ Dropbox/Diplomska/SDB-1.3.3".
