OpenHarmony应用构建工具Hvigor的构建流程

本文主要是介绍OpenHarmony应用构建工具Hvigor的构建流程，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

前言

OpenHarmony 应用和服务使用 Hvigor 作为工程的构建工具。本篇文章将介绍 Hvigor 的构建流程，通过修改脚本配置使 Hvigor 执行自定义任务。

Hvigor 的构建流程

加载命令行参数和环境变量；
初始化项目结构，创建 Project 和 Module 实例；
配置项目插件和任务流；
执行任务流；

// hvigor/index.js
// LiftOff 命令行辅助工具
const cli = new LiftOff({name: 'hvigor',processTitle: make_title.makeTitle('hvigor', process.argv.slice(2)),moduleName: exports.hvigorPath,// @ohos/hvigor-baseconfigName: "hvigorFile",v8flags: v8flags,extensions: interpret.jsVariants
});
// cli options定义所有的可支持的命令行
const parser = yargs.usage("Usage", cli_options.cliOptions);
// 解析命令行
const opts = parser.argv;
function run() {cli.prepare({cwd: opts.cwd,require: opts.require,completion: opts.completion,}, function (env) {// help 指令if (opts.help) {yargs.usage('Usage: hvigor [options]').example('hvigor assembleApp', 'Do assembleApp task').help('h').alias('h', 'help').epilog('copyright 2021').argv;exit.exit(0);}// version 指令if (opts.version) {_log.info('CLI version:', cliVersion);_log.info('Local version:', env.modulePackage.version || 'Unknown');exit.exit(0);}// 设置日志等级evaluateLogLevel();
// 判断当前 nodejs工具版本信息const LOWEST_VERSION = "v14.18.3";if (process.version < LOWEST_VERSION) {_log.warn(`node version: ${process.version}`);_log.warn(`node version cannot be lower than ${LOWEST_VERSION}`);process.exit(-1);}// 1. 加载命令行参数和环境变量init_env_config_props.initEnvConfigProps(env, opts);cli.execute(env, env.nodeFlags, function () {return __awaiter(this, void 0, void 0, function* () {const taskBeginTime = process.hrtime();// 执行具体的 Hvigor 任务yield process_utils.processUtils(opts, env);const taskEndTime = process.hrtime(taskBeginTime);const realTime = pretty_hrtime.default)(taskEndTime);if (0 == profile_js.profile.executed) {_log.error(`No task found to execute in project!`);}_log.info(`BUILD SUCCESSFUL in ${realTime}`);});});});
}

执行具体的 Hvigor 的任务

// hvigor/src/process-utils.js
function processUtils(opts, env) {···// 2. 初始化项目结构，创建 Project 和 Module 实例；init.init(env);// 3. 配置项目插件和任务流；const project = configuration.configuration(env);// 4. 执行任务流；const executeMode = env.configProps.get(modeAlias);switch (executeMode) {···}
}

1. 加载命令行参数和环境变量

读取命令行参数，并把参数和配置文件的路径放入全局配置项中。

// hvigor/src/init-env-config-props.js
function initEnvConfigProps(env, opts) {···// 获取项目级别 build-profile.json5 文件路径，[项目路径]/build-profile.json5const configFilePath = path.resolve(process.cwd(), hvigor_base.HvigorCommonConst.PROJECT_CONFIG_FILE);···const properties = new Map();// 获取命令行 prop(p) 参数，放入 Map 中if (opts.prop !== undefined) {[].concat(opts.prop).forEach((value) => {const arr = value.split('=');properties.set(arr[0], arr[1]);});}// 把"项目级别 build-profile.json5 文件路径"、"命令行 prop(p) 参数集合"和"命令行 mode(m) 模式参数"配置进环境变量中env.configProps = new Map([[configFileName, configFilePath],[propertiesAlias, properties],[modeAlias, opts.mode]]);return configFilePath;
}

2. 初始化项目结构，创建 Project 和 Module 实例

工程结构实例化。

// hvigor/src/lifecycle/init.js
function init(env) {// env.modulePath 是在命令行辅助工具 LiftOff 中加载的模块函数，"modulePath": "[项目路径]/node_modules/@ohos/hvigor-base/index.js",const vigorConfigInst = require(env.modulePath).vigorConfigInst;// 把从命令行加载来的 prop(p) 参数放入 vigorConfigInst 实体的 ExtraConfig 中vigorConfigInst.setExtraConfig(env.configProps.get(propertiesAlias));// 初始化项目，参数：[项目路径]/build-profile.json5，[项目路径]vigorConfigInst.initRootProject(path.resolve(env.cwd, hvigor_base.HvigorCommonConst.PROJECT_CONFIG_FILE), env.cwd);
}

// hvigor-base/index.js
exports.vigorConfigInst = new VigorConfig();
class VigorConfig {constructor() {this._log = hvigor_log_js.HvigorLogger.getLogger(VigorConfig.name);this._project = undefined;this._projectDir = "";this._projectConfigFile = "";this._extraConfig = new Map();}···// 初始化项目，参数：[项目路径]/build-profile.json5，[项目路径]initRootProject(projectConfigFile, projectRootDir) {// 配置项目级别 build-profile.json5 文件路径this._projectConfigFile = projectConfigFile;// 配置项目根路径this._projectDir = projectRootDir;// 创建项目实例，参数：[项目名称]，[项目路径]const projectImpl = new project_impl_js.ProjectImpl(path.basename(projectRootDir), projectRootDir);// 读取 [项目路径]/build-profile.json5 配置数据const projectStructureOpt = json5_reader_js.Json5Reader.getJson5Obj(this._projectConfigFile);···// 从配置文件中读取项目下的全部 Modules projectStructureOpt.modules?.forEach(module => {// 校验 Module 配置参数validate_util_js.ValidateUtil.validateModule(module);// 添加子项目，根据配置文件中 Modules 循环创建 Module 实例，参数：项目实例，Module 名称，Module 的路径projectImpl.addSubProject(new module_impl_js.ModuleImpl(projectImpl, module.name, module.srcPath));});this._project = projectImpl;return projectImpl;}
}
class ValidateUtil {static validateModule(module) {if (module.name === undefined) {this.logger.errorMessageExit(`Project level build-profile.json5 lose required property: module-name`);}if (module.srcPath === undefined) {this.logger.errorMessageExit(`Project level build-profile.json5 lose required property: module-srcPath`);}}
}

Project 实现类

// hvigor-base/src/impl/project-impl.js
class ProjectImpl extends default_module_impl.DefaultModuleImpl {constructor(moduleName, moduleDir) {super(moduleName, moduleDir);// 配置项目级别 build-profile.json5 文件路径this._projectStructureFile = path.resolve(moduleDir, common_const.HvigorCommonConst.PROJECT_CONFIG_FILE);this._subProjects = new Map();}···
}

Module 实现类

// hvigor-base/src/impl/module-impl.js
class ModuleImpl extends default_module_impl.DefaultModuleImpl {constructor(project, moduleName, moduleDir) {super(moduleName, moduleDir);this._project = project;}···
}

默认 Module 实现类

// hvigor-base/src/impl/default-module-impl.js
class DefaultModuleImpl {constructor(moduleName, modulePath) {this._moduleName = moduleName;this._modulePath = modulePath;// 获取项目和模块的 package.json 文件路径this._packageJsonPath = path.resolve(modulePath, "package.json");// 获取项目和模块的 hvigorfile.js 文件路径this._buildFilePath = path.resolve(modulePath, common_const.HvigorCommonConst.BUILD_FILE_NAME);}···
}

3. 配置项目插件和任务流

加载 hvigorfile.js 文件中配置的任务脚本。

// hvigor/src/lifecycle/configuration.js
function configuration(env) {// 整个项目的结构在 init 中初始化完成，读取 vigorConfigInstconst vigorConfigInst = require(env.modulePath).vigorConfigInst;// 通过 vigorConfigInst 获取项目实例const project = vigorConfigInst.getProject();// 获取项目全部的 Module 实例，遍历加载任务脚本for (const subModule of project.getAllSubProjects()) {// 获取 Module 的 hvigorfile.js 文件路径const subModuleVigorFileJs = subModule.getBuildFilePath();// 加载任务脚本configModule(subModule, subModuleVigorFileJs);}// 获取 Project 的 hvigorfile.js 文件路径const projectVigorFileJs = path.resolve(env.cwd, hvigor_base.HvigorCommonConst.BUILD_FILE_NAME);// 加载任务脚本configModule(project, projectVigorFileJs);return project;
}function configModule(module, hvigorFilePath) {// FA 模型// 工程级别// module.exports = require('@ohos/hvigor-ohos-plugin').legacyAppTasks// 模块级别// module.exports = require('@ohos/hvigor-ohos-plugin').legacyHapTasks// module.exports = require('@ohos/hvigor-ohos-plugin').legacyHarTasks// Stage 模型// 工程级别// module.exports = require('@ohos/hvigor-ohos-plugin').appTasks// 模块级别// module.exports = require('@ohos/hvigor-ohos-plugin').hapTasks// module.exports = require('@ohos/hvigor-ohos-plugin').harTasks// 加载 hvigorFile 任务脚本const moduleExported = require(hvigorFilePath);// 配置 Project 和 Module 的任务流const pluginNTasks = moduleExported(module);module.exported = pluginNTasks;// 绑定创建的 Plugin 对象到 Project 实例和 Module 实例上module.bindPlugin(pluginNTasks.plugin);
}

4. 执行任务流

根据命令行 mode 参数判断要执行任务流的级别。

// hvigor/src/process-utils.js
// 从环境变量中获取 mode(m) 参数
const executeMode = env.configProps.get(modeAlias);// 根据 mode 判断要执行任务流的级别
switch (executeMode) {case hvigor_base.HvigorBuildConst.PROJECT_MODE: // projectexecute_task.execute(project, true, opts).then(outputInfo);break;case hvigor_base.HvigorBuildConst.MODULE_MODE: // moduleexecute_task.executeModuleTask(project, opts).then(outputInfo);break;case undefined: // 未配置execute_task.execute(project, false, opts); execute_task.executeModuleTask(project, opts).then(outputInfo);break;default:_log.error(`Unknown mode '${executeMode}' specified in command line,Please check!`);
}

执行任务

//hvigor/src/lifecycle/execute-task.js
function executeModuleTask(project, opts) {// 获取 prop(p) 参数中 module 的取值const modules = hvigor_base.vigorConfigInst.getExtraConfig().get("module");// 如果不指定 module 则默认执行所有 Module 任务if (modules === undefined) {// 从项目实例中获取全部 Module 并执行任务yield Promise.all(project.getAllSubProjects().map((module) => {execute(module, false, opts);})).catch(error => {_log.error(error);});}else {// 如果指定 module 则从项目级别 build-profile.json5 配置文件中查找匹配的 Module ，如果存在则执行任务yield Promise.all(modules.split(",").map((value) => {const values = value.split("@");const module = project.findModuleByName(values[0]);if (module === undefined) {_log.errorMessageExit(`Unknown module '${values[0]}' in command lines,Please check!`);}execute(module, true, opts);})).catch(error => {_log.error(error);});}
}
// 执行任务流
function execute(model, shouldCheckTask, opts) {return __awaiter(this, void 0, void 0, function* () {// 从命令行获取需要执行的任务列表const tasks = opts._;// 如果没配置则执行 default 任务const toRun = tasks.length ? tasks : ['default'];···const moduleName = model.getName();// [项目路径]/node_modules/@ohos/hvigor-base/index.js.Hvigorconst HvigorClass = require(index.hvigorPath).Hvigor;// 项目打包工具的主入口const vigorInst = new HvigorClass();// 注册任务const registryTasks = register_exports.registerExports(vigorInst, model.exported);if (needSync) {profile_js.profile.executed += 1;yield sync.sync(model, registryTasks, vigorInst);return;}// 筛选最终要执行的操作const finallyToRun = toRun.filter((taskName) => {return registryTasks.has(taskName);});// 指定具体要执行的模块,但是找不到对应的任务if (!needSync && shouldCheckTask && finallyToRun.length === 0) {_log.errorMessageExit(`Task ${toRun} not found in module:${moduleName}.`);}// 未指定具体要执行的模块,没有可执行任务时直接返回if (finallyToRun.length === 0) {_log.debug(`No task found to execute in ${moduleName}!`);return;}profile_js.profile.executed += finallyToRun.length;// series:串行 parallel:并行const runMethod = opts.series ? 'series' : 'parallel';// 执行任务流vigorInst[runMethod](finallyToRun)(function (err) {if (err) {_log.errorExit(err.message);}});});
}

注册任务

// hvigor/src/register-exports.js
function registerExports(vigorInst, hvigorFileObj) {const registryTasks = new Map();const taskNames = Object.keys(hvigorFileObj);if (taskNames.length) {taskNames.forEach((taskName) => {const exportObj = hvigorFileObj[taskName];// plugin 不会被注册if (exportObj instanceof Task) {const task = exportObj.registry();vigorInst.task(taskName, task);registryTasks.set(taskName, exportObj instanceof DefaultSyncTask);}});}return registryTasks;
}

创建 Project 任务服务实例

基于持久化 project 的模型层提供的数据，经过处理后,提供给打包app任务流需要使用的服务和数据

// hvigor-ohos-plugin/src/tasks/service/project-task-service.js
class ProjectTaskService extends task_service.TaskService {constructor(project, projectModel) {super(projectModel);// 初始化 Project 中 Module 需要打包的目标项集合this.initProductData = () => {// 遍历所有模块this._project?.getSubProjects().forEach((value) => {const moduleName = value.getName();const plugin = value.getPlugin();if (plugin === undefined) {throw new Error(`Cannot find build file 'hvigorfile.js' in module ${moduleName}`);}const moduleTargetDataArr = [];if (plugin instanceof hap_plugin.HapPlugin) {// 获取项目级别 build-profile.json5 中 modules 里配置的 name 匹配的配置项const appModuleOpt = this._projectModel?.getModuleProfileOpt(moduleName);// 获取 module 配置中 targets 配置项const appModuleConfigTargets = appModuleOpt?.targets;// 获取 module 的 taskService 中 targetData 信息const targetDataMap = plugin.getTaskService().getTargetDataMap();// 遍历 Module 中需要打包的目标项targetDataMap.forEach((targetData, targetName, targetMap) => {// 该target需要打包，并且在项目级别 build-profile.json5 的 targets 中配置if (targetData[1] && array_util.getElementFromArr(appModuleConfigTargets, targetName) !== undefined) {moduleTargetDataArr.push(targetData[0]);}});this._productDataMap.set(moduleName, moduleTargetDataArr);}});};this._project = project;// 获取命令行中配置的需要打包的 product 如果未配置则默认为 defaultthis._targetProduct = find_target_product.findTargetProduct(projectModel);// 创建 SDK 工具实例,传入编译版本和 toolchains 工具名称this._sdkInfo = new sdk_info_js.SdkInfo(projectModel.getCompileApiVersion(), [sdkmanager_common.ComponentPath.TOOLCHAINS]);// 创建路径信息实例this._pathInfo = new project_path_info_iml.ProjectPathInfoIml(projectModel, this._targetProduct.name);this._productDataMap = new Map();this.initProductData();}···

Hvigor 自定义任务

创建任务

继承 Task 类实现自定义任务。创建自定义任务 command.js 文件,输出工程名称。

// command.js
const hvigor_base = require("@ohos/hvigor-base");class Command extends hvigor_base.Task {_taskService = null_logger = hvigor_base.HvigorLogger.getLogger(Command.name);constructor(taskService) {super();this._taskService = taskService;}registry = () => {return this.doTaskAction;}doTaskAction = (cb) => {this._logger.info(`CustomCommand`);this._logger.info(`ProjectName : ${this._taskService.getProjectModel().getName()}`);cb();}
}
exports.Command = Command;

修改任务脚本

修改任务脚本把自定义任务加入到任务流中。

// hvigorfile
const command_js = require('./command');
const hapTasks = require('@ohos/hvigor-ohos-plugin').hapTasks;module.exports = (module) => {const tasks = hapTasks(module);const taskService = tasks['plugin'].getTaskService();tasks.command = new command_js.Command(taskService);return tasks;
}
