Topic: Java Version
Grahame Grieve (May 31 2016 at 23:19):
Hey All. Bad news, I'm afraid. I'm upgrading the tooling to require Java 8. I have several dependencies that requrie Java 8, and I can't hold it off any longer
Grahame Grieve (May 31 2016 at 23:20):
I'll hold off for a little while - maybe 24 hours max? - so that anyone can raise objections as to why that's not possible
David McKillop (Jun 01 2016 at 00:19):
Does that explain the following on my local build where my machine uses Java 8?

Grahame Grieve (Jun 01 2016 at 02:15):
no
Grahame Grieve (Jun 01 2016 at 02:17):
that commit is to fix your problem, David
Grahame Grieve (Jun 01 2016 at 20:23):
As of my next commit, the build tool requires Java 8. It will crash about 30 seconds into the build if you do not have Java 8
Grahame Grieve (Jun 01 2016 at 20:24):
actually, my next set of commits
Lloyd McKenzie (Jun 01 2016 at 20:38):
Specifically, a Java 8 JDK, not just a runtime environment
Grahame Grieve (Jun 01 2016 at 20:51):
yes
Bryn Rhodes (Jun 06 2016 at 22:49):
So, I'm getting "Unable to check java library version"?
Bryn Rhodes (Jun 06 2016 at 22:49):
I've verified I'm using a 1.8 JDK.
Bryn Rhodes (Jun 06 2016 at 22:50):
I've also done a complete delete/re-get (twice actually).
Bryn Rhodes (Jun 06 2016 at 22:50):
Any thoughts?
Bryn Rhodes (Jun 07 2016 at 00:24):
FYI, the problem ended up being that the RemittanceOutcome codesystem generated a class name of "RemittanceOutcome", but a class file name of "Remittanceoutcome.java". Fixed that difference manually and now the build works for me...
Brian Postlethwaite (Jun 08 2016 at 05:03):
@Bryn Rhodes How did you fix that? The file gets autogenerated with the wrong case.
Brian Postlethwaite (Jun 08 2016 at 05:07):
Ok, don't know why. But its ok now.
Did find quite a few inconsistencies with the RemittanceOccurrence codesystem.
Brian Postlethwaite (Jun 08 2016 at 05:08):
@Paul Knapp, do you mind if I commit the changes for this code system?
The Partial value was missing from definitions around the place. I assume it is meant to be there.
Brian Postlethwaite (Jun 08 2016 at 07:55):
@Bryn Rhodes this commit should have fixed the enum case issue that you had.
Bryn Rhodes (Jun 08 2016 at 15:22):
Thanks @Brian Postlethwaite!
Vadim Peretokin (Feb 07 2017 at 10:08):
@Grahame Grieve Are you running JDK 7? org.hl7.fhir.convertors specifies JavaSE-1.7 but 1.7 JDK isn't publicly available anymore, save to Oracle support customers (http://www.oracle.com/technetwork/java/javase/downloads/index.html). It's just a warning, but still, bit of a hard requirement to meet
Grahame Grieve (Feb 07 2017 at 10:50):
I'm running jdk8. have to, for the build. I don't know anything about why stupid java plays games like this
Vadim Peretokin (Feb 07 2017 at 10:57):
Oh, easy fix then, just up the JRE version specified in the project :)
Right-click on the converters project, properties, Java Build Path, Libraries tab. Remove JRE 1.7, hit Add Library, JRE System Library, select "Workspace Defailt JRE (jre1.8...)". Same for fhir.rdf project.
