[tomsontom]

what version of e(fx)clipse is this?

[zosrothko]

e(fx)clipse - IDE 3.3.0.201805280700 org.eclipse.fx.ide.feature.feature.group Eclipse.org

[tomsontom]

I guess there's a reason that you are on such old versions?

[zosrothko]

Yeap... At our company, we are stuck to Java 1.8 because of our customers. Thus the target Eclipse platform we can take should run with 1.8. We make the choice to use Photon.
