| Re: [tycho-user] Tycho 2.1.0 cannot run tests with Java 1.8 anymore. Bug? |
Hi
The OCL jobs at https://ci.eclipse.org/ocl/ perform a weekly test that the latest build is useful on Oxygen through to 2021-03 using the appropriate Java for each release. This presumably gives adequate Java 8/11 variance.
The Ecore/UML standalone jobs also test that the legacy functionality works on a Java 5 platform.
That is what I mean by test for Java 5/8/11.

Hi Ed,Java 8 is dead as far as significant parts of Eclipse are now concerned.yes, for new code that is right and about time. For plug-ins, alas, you need to make sure that they work with pre-2020-09 versions of Eclipse, too, and for those your users may very well still use Java 1.8. In fact, very old versions of Eclipse, which your users still rely on for one plug-in or another, don't even run on Java 11. Call me paranoid, but I would really like to run my tests against both new versions of Eclipse on Java 11 and old versions of Eclipse on Java 1.8.Java 11 is pretty much mandatory UI-wise though you can still test for Java 8 or even Java 5 standalone.I am afraid I don't understand. What do you mean by "test for"?You may find https://bugs.eclipse.org/bugs/show_bug.cgi?id=569379 provides some helpful clues after I attempted a similar migration.Thank you. I'll have a look. What I don't quite get is why the *forked* JVM with the Surefire Booter needs to be a Java 11 one, since Surefire and JUnit 5 themselves are still compatible with Java 1.8. At least for running tests against older versions of Eclipse, which themselves run just fine on Java 1.8, that should be not be necessary. (All the Tycho plug-ins running as part of the "mvn" JVM can absolutely require Java 11; I am just talking about the test runtime.) Best wishes, Andreas
