octave-config -p VERSION fails after update to 4.0.2

[skymoo (Adam Mercer)]

Just updated a couple of my machines to octave-4.0.2 and some automatic builds that use octave are now failing. Specifically they are failing when they try to determine the version of octave that is installed:

$ octave-config -p VERSION
No Java runtime present, requesting install.
$

However a JRE is installed:

$ which java
/usr/bin/java
$

I have the following variants enabled:

$ port installed octave
The following ports are currently installed:
  octave @4.0.2_0+accelerate+app+docs+fltk+gfortran+graphicsmagick+java+qt4gui+sound (active)
$

Between this ticket and a discussion on the ​users mailing list, it seems the java variant is causing problems.
As of r149046, it is no longer a default variant.
octave uses the ​java PortGroup, which apparently did not work on your setup.
To fix the problem, we would either need to figure out why the java PortGroup did not work in your case or simply reinstall octave without the java variant.

Thanks disabling the java variant has done the trick with my local machine. Now to try the others...

[skymoo (Adam Mercer)]

That did the trick, thanks! My jobs are building again!

Under the circumstances, I believe we should call this fixed.
If someone wants to do more work with the java PortGroup, then we should open a ticket for that specific purpose.
