Visual Studio Code – Is there a way to set up the build order in a JAVA project on VSCode?

Altought @JialeDu is right and theres no emmbed way to do it, you can also try to make a task build in VS Code, here's how for future reference:

1. Open your Java project in VS Code.
2. Open the Command Palette (Ctrl/Cmd + Shift + P) and type "task" to see the available options.
3. Choose the option "Tasks: Configure Task Runner".
4. Select "Java" from the list of templates, if available, or choose "Others" if the Java template is not available.
5. Enter the following task configuration:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Build",
            "type": "shell",
            "command": "javac",
            "args": [
                "${file}"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

6. Save the file as tasks.json in the .vscode directory of your project.

Now you can build your Java project by opening the Command Palette and typing "run build task", or by using the keyboard shortcut (Ctrl/Cmd + Shift + B).

If you have multiple Java projects in the same workspace, you can modify the args in the task configuration to specify which project to build. Here is an example:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Build Project 1",
            "type": "shell",
            "command": "javac",
            "args": [
                "-cp",
                "lib/*",
                "src/main/java/com/project1/Main.java"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        },
        {
            "label": "Build Project 2",
            "type": "shell",
            "command": "javac",
            "args": [
                "-cp",
                "lib/*",
                "src/main/java/com/project2/Main.java"
            ],
            "group": {
                "kind": "build"
            }
        }
    ]
}

If your Java projects are also Maven projects, you can use the Maven command to build them instead of javac. Here is an example task configuration for building Maven projects:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Build Project 1",
            "type": "shell",
            "command": "mvn",
            "args": [
                "clean",
                "install"
            ],
            "options": {
                "cwd": "${workspaceFolder}/project1"
            },
            "group": {
                "kind": "build",
                "isDefault": true
            }
        },
        {
            "label": "Build Project 2",
            "type": "shell",
            "command": "mvn",
            "args": [
                "clean",
                "install"
            ],
            "options": {
                "cwd": "${workspaceFolder}/project2"
            },
            "group": {
                "kind": "build"
            }
        }
    ]
}

In this example, the command is set to mvn and the args specify the clean and install goals. The options field is used to specify the current working directory (cwd) for each project, so that the correct Maven project is built. You can run either task by opening the Command Palette and typing "run build task", then selecting the desired task from the list.
