<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">Possibly I didn't explain this very well.</p>
<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">There are at least four moving parts:</p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;"> - the end application</p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;"> - your code (which I'll call zorbage for this explanation, even though that is a generalisation)</p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;"> - the GDAL java bindings</p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;"> - the installed version of GDAL (the native libraries).</p>
<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">Your options are to specify the GDAL java bindings (or not), and to try to influence the other parts. </p>
<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">Since zorbage isn't providing the native libraries, what you put in your maven dependencies makes no difference as to whether anything you do works or not.</p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">It might not even be installed.</p>
<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">If you specify a version of the java bindings, they'll be added as a dependency by default. You can choose whether to bundle them, or assume its provided.</p>
<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">The key is that the end-application can override the version of the java bindings. </p>
