当构建你的模组来分发给用户时，它会被重新映射到中间映射，这会导致开发环境和生产环境（如原版启动器）之间出现轻微的不一致。 尽管这种问题很少见，但在发布之前在生产环境中测试你的模组还是有意义的。

通用选项

服务器和客户端任务都继承自同一个 AbstractProductionRunTask 类。 这意味着他们共享以下选项：

tasks.register("prodServer", net.fabricmc.loom.task.prod.ServerProductionRunTask) {
    // A collection of mod jars that will be used when running the game. The mods must be remapped to run with intermediary names.
    // This uses a Gradle ConfigurableFileCollection allowing the files to come from a variety of sources.
    mods.from file("mod.jar")
    mods.from configurations.exampleConfiguration

    // A list of additional JVM arguments to pass to the game.
    jvmArgs.add("-Dfabric.client.gametest")

    // A list of additional program arguments to pass to the game.
    programArgs.add("--example")

    // The directory to run the game in.
    runDir = file("run")

    // Specify the Java toolchain to use when running the game.
    // Defaults to the Java version being used to run Gradle.
    // See https://docs.gradle.org/current/userguide/toolchains.html#sec:plugins_toolchains
    javaLauncher = javaToolchains.launcherFor {
        languageVersion = JavaLanguageVersion.of(21)
    }
}

服务器

服务器生产运行任务使用您从 Fabric 网站下载的相同服务器启动器，保证环境尽可能接近生产环境。

tasks.register("prodServer", net.fabricmc.loom.task.prod.ServerProductionRunTask) {
    // The version of the Fabric Installer to use. This must be specified.
    installerVersion = "1.0.1"

    // The version of Fabric Loader to use.
    // Defaults to the version of Fabric Loader that the project is using.
    loaderVersion = "0.16.10"

    // The version of Minecraft to use.
    // Defaults to the version of Minecraft that the project is using.
    minecraftVersion = "1.21.4"
}

服务器任务具有使用不同版本的 Minecraft 运行模组的独特能力，如果你正在开发跨版本模组会很有用。

客户端

tasks.register("prodClient", net.fabricmc.loom.task.prod.ClientProductionRunTask) {
    // Whether to use XVFB to run the game, using a virtual framebuffer. This is useful for headless CI environments.
    // Defaults to true only on Linux and when the "CI" environment variable is set.
    // XVFB must be installed, on Debian-based systems you can install it with: `apt install xvfb`
    useXVFB = true

    // Optionally configure the tracy-capture executable.
    tracy {
        // The path to the tracy-capture executable.
        tracyCapture = file("tracy-capture")

        // The output path of the captured tracy profile.
        output = file("profile.tracy")

        // The maximum number of seconds to wait for tracy-capture to stop on its own before killing it.
        // Defaults to 10 seconds.
        maxShutdownWaitSeconds = 10
    }
}
