This has been a mega-pain ever since Java became totally unstable with the introduction of modules in Java 9 and now made even worse by the effective removal of Eclipse support for the not-EOL Java 8.
See https://www.eclipse.org/lists/cross-project-issues-dev/msg16293.html in which I wrote
The recent "Errors when running 2018-12 RC2 on Java 11" thread is just one of many 'new'-Java problems.
The instability of Java is clearly a major PITA, so that each of Java 8, 9, 10, 11 has resulted in significant breakages that have gradually been ameliorated.
As a user I see Eclipse as a nice platform that has for many years hidden the Windows/Linux/MacOS eccentricities. Less obviously, the platform now needs to hide the Java 7/8/9/10/11 eccentricities, so that for the most part an Eclipse application just works. We should not depend on each project rebuilding with latest-Java workarounds.
Currently each new Java eccentricity seems to be accommodated by dubious workarounds that do not hide the problem from the user. e.g. I now have to import javax.annotation into each of my test plugins.
It seems that we need to offer two options.
a) a default Eclipse that maximally hides the Java eccentricities to give a good user experience. This may require a 're-modularizer' to counteract Java's incessant migrations.
b) -strict Eclipse for those who want to be precisely in tune with a Java eccentricity.
This obvservation/suggestion seemed well received in principle, but there is always the problem of resources/funding, so Eclipse prefers to require each user/developer to discover/diagnose/accommodate each new Java instability.
In the case of your 50 changes, I suggest introducing a common dependency that acquires javax etc so that next time you only need to make a change in one place.
