Idea激活2022.1.4(2022.1.4 Android导入compose的 Maven 组遇到的问题)

1）Unresolved reference: compose 提示Add ‘jcip.annocations.jar’ to path

按提示add后会import net.jcip.annotations.Immutable 这时@Immutable不报错了 但是import androidx.compose.runtime.Immutable依然报错

2）Google搜索import androidx.compose.runtime会指向官方提示库导入文档 https://developer.android.com/jetpack/androidx/releases/compose-runtime?hl=zh-cn#kts

文档显示Compose Runtime是Compose 编程模型和状态管理的基本组件，以及 Compose 编译器插件的目标核心运行时。

Compose 由 androidx 中的 7 个 Maven 组 ID 构成。每个组都包含一套特定用途的功能，并各有专属的版本说明。

下表介绍了各个组及指向其版本说明的链接。

声明依赖项：如需添加Compose的依赖项，要在应用或模块的build.gradle文件中添加所需工件的依赖项（build.gradle有Project和Module）

dependencies {

    implementation(“androidx.compose.runtime:runtime:1.1.0-rc01”)

    implementation(“androidx.compose.runtime:runtime-livedata:1.1.0-rc01”)

    implementation(“androidx.compose.runtime:runtime-rxjava2:1.1.0-rc01”)

}

android {

    buildFeatures {

        compose = true

    }

    composeOptions {

        kotlinCompilerExtensionVersion = “1.1.0-rc01”

    }

    kotlinOptions {

        jvmTarget = “1.8”

    }

}

3）代码行的报错没有了，但是提示构建失败Build: failed 控制台打印报错

e: This version (1.1.0-rc01) of the Compose Compiler requires Kotlin version 1.6.0 but you appear to be using Kotlin version 1.6.10 which is not known to be compatible.  Please fix your configuration (or `suppressKotlinVersionCompatibilityCheck` but don’t say I didn’t warn you!).

FAILURE: Build failed with an exception.

* What went wrong:

Execution failed for task ‘:app:compileDebugKotlin’.

> Compilation error. See log for more details

e:这个Compose Compiler的版本(1.1.0-rc01)需要Kotlin版本1.6.0，但你似乎使用的是Kotlin版本1.6.10，这是不知道是兼容的。请修复您的配置(或“suppressKotlinVersionCompatibilityCheck”，但不要说我没有警告你!)

失败:构建失败并出现异常。

*哪里出了问题:

task ‘:app:compileDebugKotlin’执行失败

>编译错误。详细信息请参见日志

5)在官网看到 Compose 与 Kotlin 的兼容性对应关系:

1.1.0-rc02兼容Kotlin1.6.10 而1.1.0-rc01兼容Kotlin1.6.0  https://developer.android.com/jetpack/androidx/releases/compose-kotlin?hl=zh-cn

仍然报错 Failed to resolve: androidx.compose.runtime:runtime-livedata:1.1.0-rc02

Add Google Maven repository and sync project

Show in Project Structure dialog

Affected Modules: app

6)FAILURE: Build completed with 7 failures.

1: Task failed with an exception.

其实就是找不到 让你在以下网址找找试试 把对应网址拷贝后仍然找不到

7）根据兼容性对应关系 改成1.1.0-rc01兼容Kotlin1.6.0

将build.gradle的dependencies{目录下对应的改成这个 classpath “org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.0

至此 问题解决

遇到一大堆报错打印英文不要怕：找到关键词然后去了解语义即可，怎么说咱也是曾是英语课代表，也过了CET6的（PS：晚上下班后 计算机专业英语词汇 要继续背起来了啊）

注意⚠️：比如好奇官方Demo里的 import com.example.owl.buildsrc.Libs的Libs的用法，搜索Libs看不到啥内容，可以搜索buildsrc找到package comIdea激活2022.1.4.example.owl.buildsrc对应文件Dependencies.kt（依赖的库都写在这个文件里）在Project的目录buildSrc下而不在Android子目录下
