无法将方法调用“记住”内联到 @androidx.compose.runtime.Composable

Question

我有一个大项目，我决定向其中添加 jetpack compose。首先，我准备了一个包含一些 @Composable 组件的独立项目，并且一切正常。然后，在编译期间向我的项目添加源和准备依赖项后，我开始收到此错误：

org.jetbrains.kotlin.backend.common.BackendException: Backend Internal error: Exception during IR lowering

我的简单代码如下所示：

@Composable
fun CatalogScreen() {

    var currentTab by remember { mutableStateOf(0) }

}

在我的项目中，我使用了 compose 1.0.1、kotlin 1.5.21、gradle 7.1.1 以及许多插件和库，包括协程和 kotlinx 序列化，但是很难删除每个依赖项并不能使代码正常工作。

也许有人遇到过这种错误并且知道什么会导致它或什么会破坏它？

Answer 1

您的模块的 build.gradle 文件中也可能缺少此内容

buildFeatures { // Enables Jetpack Compose for this module
    compose = true
}
composeOptions {
    kotlinCompilerVersion versions.kotlin
    kotlinCompilerExtensionVersion versions.composeCompiler
}

Answer 2

解决方案非常棘手：

在我的buildSrc buildGradle 中，我有以下代码：

repositories {
    google()
    jcenter()
    maven(url = "https://storage.googleapis.com/r8-releases/raw")
}

plugins {
    `kotlin-dsl`
}

dependencies {
    implementation("com.android.tools.build:gradle:7.0.0")
}

将api(kotlin("gradle-plugin:1.5.21")) 添加到依赖项解决了构建问题。

我将把这条线索留给会影响这个问题的其他开发者。

Answer 3

我听说每当出现“内部后端编译器错误”时，它都是由编译器本身引起的，应该报告。尝试从 Studio Templates 创建一个新项目，看看它是否可以编译。如果是这样，那么只需将您的代码复制粘贴到该代码中即可。

谢谢！
