OpenHarmony应用编译 - 如何在源码中编译复杂应用(3.2-Release)
[md]# 概述
## 文档环境
开发环境:Windows 11
编译环境:Ubuntu 22.04
开发板型号:DAYU 200(RK3568)
系统版本:OpenHarmony-3.2-Release
涉及仓库:[applications\_launcher](
https://gitee.com/openharmony/applications_launcher
)
## 功能简介
* 在OpenHarmony系统中预安装应用的hap包会随系统编译打包到镜像中,目前有两种编译预安装应用hap包的方式,一种为随系统编译时,编译应用源码生成hap包的方式,另一种是将已生成的hap包放入系统源码中,再进行打包的方式。后者需要开发者使用DevEco Studio或其它途径,把应用源码编译构建为hap包,再将hap放入系统源码中。
* 本文档以系统应用**Launcher**为例,带大家了解如何通过系统源码编译应用的方式来打包预安装应用。
# 3.2-Release系统编译Launcher
1.删除或注释系统中默认的**Launcher**应用**hap**包编译方式。
文件位置:**applications/standard/hap/BUILD.gn**
```cpp
group("hap") {
deps = [
...
# "//applications/standard/hap:launcher_hap", // 直接删除或注释,不参与编译
# "//applications/standard/hap:launcher_settings_hap", // 直接删除或注释,不参与编译
...
]
}
```

)
2.在**applications/standard/launcher/product/phone**目录中增加**BUILD.gn**文件。
![](
https://harmonyos.oss-cn-beijing ... 384a364c4d1ffe7.png
)
内容如下:
```cpp
import("//build/ohos.gni")
ohos_hap("launcher_hap") {
hap_profile = "src/main/module.json"
deps = [
":launcher_js_assets",
":launcher_resources",
]
certificate_profile = "../../signature/launcher.p7b"
hap_name = "Launcher_OS"
part_name = "prebuilt_hap"
subsystem_name = "applications"
js_build_mode = "release"
module_install_dir = "app/com.ohos.launcher"
}
ohos_js_assets("launcher_js_assets") {
ets2abc = true
source_dir = "src/main/ets"
}
ohos_resources("launcher_resources") {
sources = [ "src/main/resources", "../../common/src/main/resources" ]
deps = [ ":launcher_app_profile" ]
hap_profile = "src/main/module.json"
}
ohos_app_scope("launcher_app_profile") {
app_profile = "../../AppScope/app.json"
sources = [ "../../AppScope/resources" ]
}
```
说明:
* 此处把产物名称**hap\_name**定义为**Launcher\_OS**是为了区分原系统源码中默认的**hap**包名称,实际可以填写为**Launcher**。
* 因为**launcher\_hap**中使用了其它**har**(common)中的资源,所以**launcher\_resources**中的**sources**需要添加依赖的**resources**资源目录,在步骤3中**launcher\_settings\_hap**
中的配置也是如此。
3.在**applications/standard/launcher/feature/settings**目录中增加**BUILD.gn**文件。

)
内容如下:
```cpp
import("//build/ohos.gni")
ohos_hap("launcher_settings_hap") {
hap_profile = "src/main/module.json"
deps = [
":launcher_settings_js_assets",
":launcher_settings_resources",
]
certificate_profile = "../../signature/launcher.p7b"
hap_name = "Launcher_Settings_OS"
part_name = "prebuilt_hap"
subsystem_name = "applications"
js_build_mode = "release"
module_install_dir = "app/com.ohos.launcher"
}
ohos_js_assets("launcher_settings_js_assets") {
ets2abc = true
source_dir = "src/main/ets"
}
ohos_resources("launcher_settings_resources") {
sources = [ "src/main/resources", "../../common/src/main/resources" ]
deps = [ ":launcher_settings_app_profile" ]
hap_profile = "src/main/module.json"
}
ohos_app_scope("launcher_settings_app_profile") {
app_profile = "../../AppScope/app.json"
sources = [ "../../AppScope/resources" ]
}
```
说明:
* 此处把产物名称**hap\_name**定义为**Launcher\_Settings\_OS**是为了区分原系统源码中默认的**hap**包名称,实际可以填写为**Launcher\_Settings**。
4.因为系统编译只可读取**json**后缀的配置文件,所以需要把应用源码中的**app.json5**和**module.json5**文件复制,并改名为**app.json**和**module.json**文件。
(1)复制**applications/standard/launcher/AppScope/app.json5**文件为**app.json。**
![](
https://harmonyos.oss-cn-beijing ... 57897cb3fd500e8.png
)
(2)复制**applications/standard/launcher/product/phone/src/main/module.json5**文件为**module.json。**
![](
https://harmonyos.oss-cn-beijing ... e6c45265f43e7c1.png
)
(3)复制**applications/standard/launcher/feature/settings/src/main/module.json5**文件为**module.json。**
![](
https://harmonyos.oss-cn-beijing ... 62562342b431bf8.png
)
5.在**applications/standard/hap/ohos.build**文件**module\_list**中增加**launcher\_hap**模块和**launcher\_settings\_hap**模块编译。
```cpp
{
"subsystem": "applications",
"parts": {
"prebuilt_hap": {
...
"module_list": [
...
"//applications/standard/launcher/product/phone:launcher_hap",
"//applications/standard/launcher/feature/settings:launcher_settings_hap",
...
]
}
}
}
```
![](

)
6.修改预编译配置**build/prebuilts\_download\_config.json**文件,把**launcher**依赖增加到**npm\_install\_path**列表中。
```cpp
{
"prebuilts_download_dir": "../OpenHarmony_canary_prebuilts",
"npm_install_path": [
"developtools/ace_ets2bundle/compiler",
"developtools/ace_js2bundle/ace-loader",
"third_party/jsframework",
"arkcompiler/ets_frontend/ts2panda",
"arkcompiler/ets_frontend/legacy_bin/api8",
"interface/sdk-js/build-tools",
"applications/standard/launcher/common",
"applications/standard/launcher/feature/appcenter",
"applications/standard/launcher/feature/bigfolder",
"applications/standard/launcher/feature/form",
"applications/standard/launcher/feature/gesturenavigation",
"applications/standard/launcher/feature/numbadge",
"applications/standard/launcher/feature/pagedesktop",
"applications/standard/launcher/feature/recents",
"applications/standard/launcher/feature/smartdock",
"applications/standard/launcher/feature/settings",
"applications/standard/launcher/product/phone"
],
...
}
```

)
7.执行预编译指令。
```cpp
bash build/prebuilts_download.sh --skip-ssl
```
可以在应用源码中看到应用内的依赖已经被正确的加载。
![](

)
8.执行源码编译指令。如果以下2个目录产物正确,则说明应用源码编译方式修改成功。
(1)在**out/rk3568/obj/applications/standard/launcher**目录中,会生成2个hap的编译产物。
![](

)
(2)在**out/rk3568/packages/phone/system/app/com.ohos.launcher**目录中,是实际系统环境中的hap包产物。

9.烧录系统验证功能。
