Exactly. 

 

Try this

OSSUnixSubprocess new

  command: '/usr/bin/java';

arguments: #('-version');

redirectStderr;

runAndWaitOnExitDo: [ :process :out :err |

err inspect

].

Indeed. This is what I think should work. And yes, I don't think the 'JAVA_HOME'  is needed. At least for this command.

Alex, let us know if Peter code worked.

Cheers,

Hi Mark,

This is what I thought. But it does not seem to work. I tried:

OSSUnixSubprocess new
  command: '/usr/bin/java';
  arguments: #('-version');
        redirectStderr;

  runAndWaitOnExitDo: [ :process :outString  |
      outString inspect
  ].

Or is it the redirectStderr that does not work properly?

Cheers,
Alexandre
