使用 JIMU 框架实现组件化

本文最后更新于：1 年前

Reference

最后实现的效果

一个模块既可以作为 application 进行单独打包，也可以作为其他模块的 library 进行打包。

从零开始实现功能

下载 JIMU 项目

JIMU 项目下载地址，后面需要用到其中的 module。

新建项目

比如 component_demo。

新建 module

比如 component1。

按照 JIMU 使用指南配置

主项目引用编译脚本

1、修改component_demo\gradle.properties为：

# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
org.gradle.jvmargs=-Xmx1536m

# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects

        classpath 'com.luojilab.ddcomponent:build-gradle:1.2.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

设置组件可独立打包

新建component_demo\app\gradle.properties和component_demo\component1\gradle.properties，并写入内容：
