SOLUTION- CREATED A NEW WORKSPACE and REIMPORTED PROJECTS

After upgrading killed eclipse, I installed a new version of eclipse 2021-03 (4.19.0).

Since I use a Mac provided by NASA, I only have Java 1.8. So I fixed the ini file.

But autocomplete doesn't work. The first time I try it I get a popup that has just 1 line, "No Default Proposals."

In my preferences, Auto Activation is enabled with a delay of 0ms, a trigger of '.' (period). I tried changing the 0 to 1ms - it didn't help, even after a restart...

I really don't want to use IntelliJ....

Of course proposals are context sensitive so it really depends on where you did this whether it's a bug or not, and if it's a bug, someone else will need to reproduce it and in that case too, more details are needed.

I got a jdk11 (or 14?) using brew, fixed the ini file, fixed my project properties, quit and restarted.
I still have the same problem...

Attached is a zip of a new, small project with the following java file:
=======

package com.ment;

public class Fubar {
static final double TWO = 2.0;
final double THREE = 3.0;

double getOne() {
return 1.0;
}

void doSomething() {
double value = this.; // type "this." and no suggestions are given
}
}

========

I submitted an example.
Here's an image of the error log (see below for the text log)

I found the "Error log view"
I attached a log and a screenshot.

bundleclass://org.eclipse.launchbar.ui.controls/org.eclipse.launchbar.ui.controls.internal.LaunchBarControl

The UI doesn't make it easy to search for conflicting bindings...
Open Type was conflicting with Go To Symbol in Workspace

Deleting the "Open Type" resolved the conflict, but I still have the other errors in the log,
and Auto-Complete is still broken.

If I close eclipse and restart it,
on the first .
it says "No default proposals"
if I hit ^space, "No template proposals"
if I hit ^space, "No template SWT proposals"
if I hit ^space, it DOES find a bunch of "chain template proposals", through getClass() and toString()...

I can also repeat this by just typing ^space after a period...
Attached is a screen capture of the non-empty chain template proposals...

I reinstalled eclipse- same result...
I put the log
(after nuking the error log, closing eclipse, re-opening it, and typing a period after "this", then exporting the log) in a reply above.
Too bad there's no way to delete one's reply...

It works for me:

index.php/fa/40414/0/

It looks like you used the same workspace with different Eclipse installations that have perspective not in the Java IDE you are currently using. This leads to some of the things in the error log.

The key binding conflict is something I've complained about but no one fixes. I'm not sure you can make it go away manually, but it doesn't generally cause problems. The Mylyn thing is also annoying and an old problem.

I don't see anything in the log that explains your Java problem...

The problem was old stuff in the workspace.
When I created a new workspace and re-imported the projects, it now works...

I had a similar problem. Installed Eclipse 4.22 and tried to use it with an old workspace from version 4.8. Got an empty autocomplete window, without any java types or methods listed. Problem solution was to check the entry "Java Proposals" in Content Assist Advanced configuration dialog:

index.php/fa/41627/0/

After checking both like showed in picture many entries in autocomplete were duplicated.

After the fix I took a look to version 4.8 configuration. A "Java Proposals (Code Recommenders)" was enabled in old workspace which is absent in new version 4.22. Therefore Java autocomplete was disabled after upgrade.
