VSCode Java doesn't handle .classpath files properly

Environment

• Operating System: Windows
• JDK version: 1.8.0_171
• Visual Studio Code version: 1.25.1
• Java extension version: 0.29.0

Steps To Reproduce

1. Copy, write, or otherwise create an Eclipse-style .classpath file, specifying a src directory.
2. Create an empty foo.java file in that directory

Current Result

Popup: foo.java isn't on the classpath.

Expected Result

No popup, working go-to-definition and similar project handling.

Additional Information

It is not entirely clear from the website that 'More information' leads to what precisely needs to be copied for the vscode-java to properly build the classpath, so if the answer turns out to be "you need more than just the .classpath", the issue just changes to "the documentation on 'Classpath is incomplete' does not provide sufficient information to actually resolve the issue."

(Also, note that the error is different from that one given when there is no classpath present. vscode-java clearly sees that there's a file there, but isn't reading it correctly.)

Commencez avec le bugrepro.zip joint et reproduisez le comportement en utilisant le fichier .classpath de style Eclipse, un répertoire src et un foo.java vide. Examinez comment la VSCode Java extension gère le .classpath et l’information « Classpath is incomplete » ; c’est terminé lorsque la popup n’apparaît plus et que go-to-definition fonctionne pour le projet.
