[tycho-dev] Does tycho build with OpenJDK 9?

[Mickael Istria]

Hi all,

I cannot build locally today, I see
"""
[ERROR] Failed to execute goal

I'm using openjdk 9 here.

Are there some restriction about which JDK should be used in order to built
Tycho? Or is there anything else I need to tweak?

IMHO all these should be updated to 1.6+. Anything older than that should
be out of question especially considering that Java 11 is supposed to drop
even 1.6. The fact that there is no OSS full featured pre 1.6 JVM makes it
more than obvious for OSS projects to me.
Jan, do you agree with bumping to Java 1.6+ so compiling with latest Java
(10 at time of writing is working well) and working with latest LTS Java (8
at time of writing).

this code is used to detect the compilation bootclasspath with useJDK=BREE
it forks a small main program using the configured JDK


AFAIK eclipse platform is still using very old JDKs (1.4) and the bytecode level of the compiled Main needs to be able to run on the oldest JDK used

Eclipse platform requires 1.8 and equinox is still at 1.7. There are
bundles at older but I don't see a reason for bundles there to stay at that
level (
http://download.eclipse.org/eclipse/downloads/drops4/I20180528-0800/buildlogs/reporeports/reports/breedata.txt
for details). Overall bundles at ancient BREE are fading out so let's
discuss the best for Tycho as a project here.
