Reference other unmanaged folders as dependencies #2853
Description
[provide a description of the issue]
Environment
- Operating System: ANY
- JDK version: 11
- Visual Studio Code version: 1.74.2
- Java extension version: Any
Steps To Reproduce
- Create a javaproject 0, a package and a class
- Create other project 1 a package and a class where you use class of project 0.
Suppose I have 4 independent Java projects: project0, project1, project2, and project3.
Inside each project, I have the src folder, and inside some packages and classes. Project 1, 2, and 3 use classes from project0.
In Eclipse, I can indicate in a section that the sources of project 0 are used. When I try something similar in VScode, I go to configure the classpath of project one and see that it includes its src folder. When I add the src folder of project0, I get the following error: "The source path must be contained in the project root folder."
I can solve this by creating the .jar of project 0 and adding it to the other projects, but this is very inconvenient when making quick tests.
I know there are tools like Maven or Ant to do these things, but I would like to know if there is any way to indicate in vscode that one project uses classes from another without having to include the .jar as a dependency.

AFAIK, if you are using project without build tools (unmanaged folder), we do not support referencing another unmanaged folder as a dependency today.

@javierjcf could we try opening the lowest common parent folder in vscode and mark the different unmanaged folders as "src" in .classpath file?
This plugin will help in setting up a local project in the parent folder.

I am looking for a way to add an external
bin/main(for example) to mysettings.json, such that it gets put on the class path. I think this ticket is asking for the same thing.cicciozell commentedon Jul 31, 2025
Same here, this VSC limitation is incredibly inconvenient and makes it impossible to use in fairly large projects.
