Salesforcedx-vscode: Autocomplete / IntelliSense not working

[lukethacoder]

Summary

Autocomplete / IntelliSense not working for Apex code. On both SObjects and built in Apex functions.

Steps To Reproduce:

1. Open Salesforce project, with existing classes.
2. Run sfdx sobject definitions refresh -u ORG_NAME
3. Type something and wait for the autocomplete

Expected result

Should show autocomplete/IntelliSense or snippet suggestion

Actual result

No autocomplete suggestions.

Additional information

SObject definitions pull in nicely.

Autocomplete doesnt work so nicely.

Additional information
VS Code Version: 1.44.2
SFDX CLI Version: 7.56.1-2773b53bf5
OS and version: Windows 10 Home, Version 1909
JAVA Version: jdk-11.0.7

Have tried using various environments, both sandboxes and scratch orgs. Projects have very few apex classes, or any other components.

Test Classes do work very nicely, and I have double checked my JAVA_HOME/JDK_HOME paths (in addition to adding "salesforcedx-vscode-apex.java.home": "C:\\Program Files\\Java\\jdk-11.0.7", to preferences.

Is there a work-around for this issue? Barring that, is there a specific version set (VSCode, SFDX) that I can install to get fully-functional autocomplete for Apex classes? For what it's worth, I'm seeing the same logging output for the Apex Language Server.

autocomplete is not working on trigger files
it works on certain variables but not work on other ones

(it shows no suggestions)

(no errors on apex language server)
vscode: 1.51.1
java: 11.0.9

@gab95 I have the same issue on autocomplete not working for variables defined inside trigger files. No issue on class files.

Thanks for the additional info @kkevinreyes

[sfsholden]

@kkevinreyes @gab95 We are looking for an open source repository where we can reproduce this issue for testing. Do either of you happen to have an example project where completions from within the trigger files are not working?

Please also include:

• VS Code Extension version
• OS and version
• Enable the setting "salesforcedx-vscode-apex.advanced.enable-completion-statistics": "true". This will output additional information into the Apex Language Server output channel. It will help us determine if this is a performance issue.

Thank you again for your help!

Still no luck with autocomplete in either class files or triggers.

enabled "salesforcedx-vscode-apex.advanced.enable-completion-statistics": "true" and got an extra 2 lines of logging (last 2 lines here).

@lukethacoder Have you tried opening a sample-app project like dreamhouse-lwc? I'd like to see if even just a basic demo works. If still no luck there, might try a more nuclear option of uninstalling the extension pack, closing vs code, reopen vs code, and reinstall the extension pack. Try to open dreamhouse-lwc again and see if that works.

If we can get it to work with dreamhouse, that at least tells us there's something about the project structure or Apex contents of the projects you're working with that the language server isn't handling properly. If we can't, that seems like a sign that maybe something with the machine's setup is causing a communication problem.

Do other language server features work? If you right click a method or Apex class reference and select "find all references" or "rename symbols", does it do so successfully? This also will help isolate the problem.

[lukethacoder]

I reckon it might be something machine related. Have nuked vs code + the sf extension pack multiple times over the past few months, again today, and even setup on a new machine with similar issues.

Installed and setup the dreamhouse-lwc project to see if that would work, but it still isn't playing nice.

Right clicking on an apex method doesn't even give the option for "find all references" or "rename symbols".

Apex Language Server logs look the same as posted up further.

Was thinking maybe my Java install might have been the issue (still might be) but I still have intelliJ and Illuminated Cloud 2 working just fine. This issue is one of the only reason I havn't fully moved over to VS Code.
