I had a hardware failure. When the machine restarted, I brought up eclipse, and it said it could not find the project. This is not the first time this has happened, that it just got lost. After a couple hours of flailing about and finding useless advice on any number of fora, I gave up.
The error was "The type java.lang.Object cannot be resolved..." followed by "The project was not built since its build path is incomplete..."
I had been working in this project for a couple weeks with no problem. Suddenly, it does not recognize the project, complains that the project file is corrupted, has lost all my run configurations (which have fairly complex command line arguments, which I now have to remember). I was unable to find any file that contained any of the command lines. And when I checked the build path, it is for the jdk-11.0.6.10-hotspot version; I checked the path and it exists.
Most of the questions dealt with fairly exotic scenarios such as building for Android. I am building and running applications on Windows 10. Every time I attempt to create a new version, it takes me days to get it back to where I was; now, doing everything I knew and everything I could try, I cannot get it to work. This should not be this difficult. I should be able to start up and have a working environment. It won't let me import the project, because it says the project is already defined in the workspace. But if it is already defined in the workspace, why can't I just build it? The package explorer comes up empty. Importing doesn't work. I am using the 2020-06 build of eclipse. This is far more difficult than it needs to be.

"Learning new stuff" does not begin to cover what is required to understand this. I have no idea what 90% of that means, and of the remaining 10% I probably want to change it, but I don't know what the 10% is, or what it can be changed to. For example, we have a git project we check things into manually, and I don't see how to even begin figuring out what needs to be understood. I've done a couple other sites and they assume I have a vocabulary of terms that they don't bother defining, assuming that somehow I know what a "bundle" is, or almost any other aspect. I am not part of that culture; all I want to do is continue development of my code that I've been working on for a couple years, and it has always worked, except the repeated setup every couple months.
Is there an "Oomph for Dummies" book. It seems I have to know everything before I can do anything. Sort of like drinking from a firehose, without the satisfaction of ending up non-thirsty.

Hi
Your invisibilities may be caused by 'smart' contexts. You can (accidentally) tunnel down to narrower scopes, so that most things are hidden. The top right view menus give you some options here,.
Using the sadly deprecated Navigator View rather than The Package Explorer gives a more truthful view that may not have some accidental tunneling. I find this very useful for conforming that oops, my already imported project really is imported. Then I can find which working set I accidentally DNDed it to.
If you have Mylyn Tasks active, it has a clever ability to focus on your recent activities. Some users find this really helpful, I have never learned to love it, so I never install Mylyn. It is possible that a crash caused some stale mementoes to be used so that Mylyn's opinion on your interesting current work is very different to yours. Try switching Mylyn tasks off until you are back in control.
Regards
Ed Willink
