w：在 build/kotlin/sessions 中检测到多个 Kotlin 守护进程会话

Question

表演./gradlew assembleRelease击中了这个问题。下面显示了整个错误日志...

w: Detected multiple Kotlin daemon sessions at build/kotlin/sessions

一些故事

在调试这个“multiple Koltin”问题时，我发现我的 NDK 没有安装。因此我进入 SDK Manager 并安装NDK (Side by side). 然后出现了工具链的问题，如下所示。

No toolchains found in the NDK toolchains folder for ABI with prefix: arm-linux-androideabi

修复是通过下载较旧的 NDK 版本来完成的，android-ndk-r19c并在我的 local.properties 中指出 NDK 路径。

本地.properties

sdk.dir=/Users/path/Library/Android/sdk
ndk.dir=/Users/path/Library/Android/android-ndk-r19c

总长DR

我尝试过的

1. ./gradlew clean && ./gradlew assembleRelease
2. 添加以下代码+步骤1

# FILE 1: Gradle.properties
org.gradle.jvmargs=-Xmx4096m -XX:MaxPermSize=1024m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

# FILE 2: app/build.gradle ( under android{} )
dexOptions {
        incremental true
        javaMaxHeapSize "4g"
}

我的项目环境

react: 16.13.1 => 16.13.1 
react-native: 0.63.2 => 0.63.2

我的项目结构

知道导致此问题的原因以及如何解决此问题吗？

Answer 1

令人难以置信的修复，似乎是一个63.x问题？因为还有人在升级到后遇到了这个问题62.263.3

修复已按照此处的建议完成

通过从 /android 中删除 .gradle 文件夹并再次运行 npm run android 解决了这个问题，它解决了这个错误。

Answer 2

似乎./gradlew -stop在 android 文件夹中运行对我有用

Answer 3

在我的情况下，仅删除 .gradle 文件夹并不能解决此问题。

但是按照此处的./gradlew clean建议在 android 文件夹中执行后，我又回到了正轨。

Answer 4

我用这个解决方案解决了这个问题。

在gradle.properties中添加以下代码

org.gradle.daemon=true
org.gradle.configureondemand=true
org.gradle.jvmargs=-Xmx4g -XX:MaxPermSize=2048m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

此外，将这些行插入 app/build.gradle 中

android{

    dexOptions {
       javaMaxHeapSize "3g"
    }
}

进行这些更改后运行.\gradle clean并.\gradle assembleRelease
