An internal error occurred during: "Initialize Workspace"

[KeplerIO]

Installed Language Support for Java by Red Hat. After installing JDK and setting path in Environment Variables and setting the java.home option in VS Code to point to the right place, I open a file "main.java" in VS Code to test. Intellisense isn't working for imports then I check Output window.

Environment

• Operating System: Windows 10
• JDK version: 1.8.0_144
• Visual Studio Code version: 1.16.1
• Java extension version: 0.10.0

Steps To Reproduce

1. Install Language Support for java by Red Hat
2. Install JDK
3. Set JDK path in Environment Variables
4. Set java.home path in VS Code settings
5. Create new projects directory and add the file "main.java"
6. Wait a few seconds and check Output window

[fbricon]

Wow I've seen my fair share of Eclipse errors, but never this one O_o What does your java.home variable look like?

[KeplerIO]

@fbricon "java.home": "C:\Program Files\Java\jdk1.8.0_144\" ofcourse with double backlashes

[fbricon]

Can you try to delete your workspace directory and try again?

[KeplerIO]

@fbricon Sure, stand by

[KeplerIO]

@fbricon Sill receiving the same errors in output window

[fbricon]

@snjeza any idea?

[KeplerIO]

@fbricon Verified this is not a JDK configuration issue as I can compile and run my "main.java" from the command-line.

[snjeza]

Create a new projects directory and add the "main.java" file

@devKepler did you create a new or open an existing directory?

[rgrunber]

Given how long ago this happened, I'm inclined to close for now. If anyone can still reproduce this feel free to re-open.
