Classpath Incomplete Warning with Eclipse-generated project

I have a lot of projects created through Eclipse that work fine. They have buildpaths and classpaths very similar to a project I'm working on currently. I created the project, made some classes, and then started implementing stuff in VSCode when the Classpath Incomplete warning popped up. The .classpath file is in the project folder, along with the .project file. I have the default src folder with a package within it that has all the source code. Everything was setup using Eclipse.

Environment

• Operating System: Win10.something
• JDK version: 1.8.0_144
• Visual Studio Code version: 1.22.1
• Java extension version: 0.22.0

Steps To Reproduce

1. Create a lot of projects in Eclipse.
2. Write all of the source in VSCode.
3. Have one project created in Eclipse repeatedly throw Classpath Incomplete warning in VSCode.

Current Result

ClassPath Incomplete warning thrown

Expected Result

No warnings being thrown

Additional Informations

If the warnings could include a diagnostic in a future version, that may help a lot.
And sorry, I can't provide a video because I can't post my source online anywhere.

Start by comparing the Eclipse-generated .classpath and .project files with the default src folder and its package, using the reported Windows, JDK 1.8.0_144, VS Code 1.22.1, and Java extension 0.22.0 environment. Reproduce the Classpath Incomplete warning and determine what project state triggers it; done means the warning is resolved or includes a useful diagnostic.
