A .dmg is an installer. In the case of the Eclipse macOS installer, I imagine it mostly just extracts the archive and moves it into the Applications folder.
Originally I was going to say that it wouldn’t be unreasonable to publish a .tar.gz for macOS but thanks Mikael Barbero for calling out https://bugs.eclipse.org/bugs/show_bug.cgi?id=507328. The comments are very informative and the (accidentally) linked article (https://lapcatsoftware.com/articles/app-translocation.html) is interesting as well. Based on reading all of that, I think it would be best to stick with .dmg. Providing instructions with a .tar.gz to drag the bundle into /Applications would take care of the issue if users actually read it and heed the warning ☺ But my guess is most people would extract the .tar.gz and run it from ~/Downloads without reading anything, then get into trouble and be mad/sad. Liviu, thanks for linking to your package page which has the instructions, but according to one of the comments removing that flag was not enough: https://bugs.eclipse.org/bugs/show_bug.cgi?id=507328#c15 Maybe things have improved since Sierra, but even so, for most users it seems like moving the bundle out of Downloads would be preferable to changing file attributes.

Just that you have to remove the quarantine attribute added by the browser after download: https://projects.eclipse.org/projects/iot.embed-cdt/downloads You're right, it can also be done this way. However, to offer a seamless experience to the end users, one have to deliver a .dmg (or .pkg).
