Build path error

[rayshencc]

Hi, I have a problem about build directory.

cd /home/ray/dev/JavaProject ; /usr/bin/env /usr/lib/jvm/java-11-openjdk-amd64/bin/java -cp /home/ray/.vscode-server/data/User/workspaceStorage/154ea3c966ddc0a55d55766b94e4cd89/redhat.java/jdt_ws/jdt.ls-java-project/bin App

This command run when I open the java project in workspace and click Run.

usr/bin/env /usr/lib/jvm/java-11-openjdk-amd64/bin/java -cp /home/ray/dev/JavaProject/originaldemo/bin App

This command run when I open the project individually rather than in a workspace and click Run.

The directory structure when opened from the workspace, springdemo is another java project

Directory structure when opened separately

I can use "java.project.outputPath" option to set build directory in file JavaProject.code-workspace and it works. However, I want to set the build directory of each project in the workspace to the root directory of the project instead of the only directory of the workspace and I set this option in file settings.json under folder .vscode in this project, but this setting doesn't seem to work.

So, I want to build and run the java project using the build directory I set up for each project in my workspace instead of using the default directory under .vscode-server or the only directory of the workspace. How should I set it up to serve my purpose or is this a bug?
