Not really on topic, but as some sane and simplifying advice - It's best to move away from IDE's like Eclipse
Their purpose is to simplify development, but from your experiences too, it's clear that they don't deliver on their promises, and complicate things instead I'd suggest you to write the code with whatever IDE you prefer, then use the command line tools separately in a serene manner My personal choice is the App Engine Python SDK for Linux, even though I'm on macOS (it includes pure code, no installer, just pure python code, granted things are usually more complicated for Java, but the same experience might apply) - You might give it a try, and if it doesn't work, you can always go back to Eclipse -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
