Trigger swift package plugin as dependency of target

[valentinvarbanov]

I want to include swift format into a custom swift package that runs every time the package is being build.

Here is the Package.swift file:

// swift-tools-version: 5.9
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "test-format",
    products: [
        // Products define the executables and libraries a package produces, making them visible to other packages.
        .library(
            name: "test-format",
            targets: ["test-format"]),
    ],
    dependencies: [
//        .package(url: "https://github.com/SimplyDanny/SwiftLintPlugins", from: "0.55.1"), // this works
        .package(url: "https://github.com/nicklockwood/SwiftFormat", from: "0.54.0"),
    ],
    targets: [
        // Targets are the basic building blocks of a package, defining a module or a test suite.
        // Targets can depend on other targets in this package and products from dependencies.
        .target(
            name: "test-format",
            plugins: [
//                .plugin(name: "SwiftLintBuildToolPlugin", package: "SwiftLintPlugins"), // this works
                .plugin(name: "SwiftFormatPlugin", package: "SwiftFormat"),
            ]),
        .testTarget(
            name: "test-formatTests",
            dependencies: ["test-format"]),
    ]
)

When I try and build the package from within Xcode (cmd + B), I get the following error (same for running tests):

When attempting to build from command line I get a different error:

Environment:

• clean swift package created using Xcode 14.2

Goal:

• SwiftFormat plugin runs when building the package and generates warnings/error that show up in the IDE/build log like:
