我已经尝试过用旧的prebuild源码构建Jetpack。但是最近我下载了一个新资源，但对我来说不起作用。这是我尝试过的。
我在中添加了源 项目/ androidx_prebuilts / out / ui / build / support_repo / androidx
在androidx目录下，我有compose和ui目录作为源文件
模块级gradle

首先，请参阅此文档：googlesource
”“本节介绍如何设置本地工作环境以构建Android源文件。您必须使用Linux或macOS；当前不支持在Windows下进行构建。” — Android文档
步骤1：
首先，我们需要从以下位置安装Repo（如果未安装） https://source.android.com/setup/build/downloading
然后在命令行中点击以下命令
mkdir bin
PATH=~/bin:$PATH
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
现在检查repo status
第2步：
创建目录，说“ AndroidCompose”
mkdir ~/AndroidCompose
cd ~/AndroidCompose
和设置git config一样（如果未设置）
git config — global user.name “Your Real Name”
git config — global user.email “you@example.com”
现在初始化仓库
repo init -u https://android.googlesource.com/platform/manifest -b androidx-master-dev
现在回购已初始化，如果我们查看〜/ AndroidCompose目录，我们将看到一个“ .repo”清单
点击
ls -a ~/AndroidCompose/.repo
“现在，您的存储库已设置为仅提取构建和运行AndroidX库所需的资源。下载代码（在我们提取6GB的同时喝咖啡）” -Android文档
步骤3： 获取所有必需来源的命令
repo sync -j8 -c
（类似于git fetch）
现在，我们已经下载了包含@Composable的正确版本的Android JetPack源
这会将所有Jetpack Compose源代码放置在“ ui”目录中
cd ~/AndroidCompose/frameworks/support/ui
点击
./studiow
启动Android Studio
重新启动Android Studio时要小心。我们需要始终从该目录开始以获取Jetpack Compose库。
在出现提示时接受许可协议。现在我们可以编辑，运行和测试了！

jetpack compose UI组件构建现已作为开发版本提供。 您不必使用Special android studio。只需以“ 0.1.0-dev01”作为版本包含所有Compose Gradle依赖项
更新：现在，Android Studio 4.0 Canary随附了Jetpack Compose和实时预览功能。
