Re: [tycho-user] Compiling with BREE JavaSE-11
|
I've just tried, and it seems to have worked. We still have build
failures but these seem to be xtend related, compilation of the
JavaSE-1.8 artifacts is working now.
This is the bug report:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=564423
Kind regards,
Alexander
