Re: [Pharo-users] Using OSSubProcess to invoke Java

June 20, 2016

      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

java -version outputs to stderr not stdout (also I don't think you need JAVA_HOME /usr/bin/java will do what is needed)

On OS X, in a terminal, if I type: /usr/bin/java -version
I obtain:
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)
Using OSSubProcess, do-it-ing the following:
OSSUnixSubprocess new
  command: '/usr/bin/java';
  arguments: #('-version');
  environmentAt: 'JAVA_HOME' put: '/Library/Java/JavaVirtualMachines/jdk1.8.0_66.jdk/Contents/Home';
  redirectStderr;
   redirectStdout;
  runAndWaitOnExitDo: [ :process :outString  |
      outString inspect
  ].
inspect an empty string.
Any idea whatâs going on?
