更新firebase-perf插件后，Android Studio项目无法编译(缺少类module-info) [英] Android studio project not compiling after updating firebase-perf plugin (Class module-info is missing)

问题描述

每个人.我正在使用gradle版本5.6.2.我这样更新了我的android studio项目依赖项:

everyone. I'm using gradle version 5.6.2. I updated my android studio project dependencies like this:

dependencies {
    classpath 'com.android.tools.build:gradle:3.5.1'
    classpath 'com.google.gms:google-services:4.3.2'
    classpath "com.google.firebase:perf-plugin:1.3.1"
}

我这样应用插件:

apply plugin: 'com.google.firebase.firebase-perf'
apply plugin: 'com.google.gms.google-services'

但是现在当我编译我的项目时，会出现此错误:

But now when I compile my project this error shows up:

Illegal class file: Class module-info is missing a super type. Class file version 53. (Java 9)

它说问题出在app \ build \ intermediates \ transforms \ FirebasePerformancePlugin \ bus \ debug \ 9 \ module-info.class

It says the problem is in app\build\intermediates\transforms\FirebasePerformancePlugin\bus\debug\9\module-info.class

里面有这个:

module com.google.gson {
    requires transitive java.sql;

    exports com.google.gson;
    exports com.google.gson.annotations;
    exports com.google.gson.reflect;
    exports com.google.gson.stream;
}

我的猜测是firebase开始使用Java 9，但我的项目当前正在使用Java8.我尝试将版本更改为9，但出现此错误:

My guess is that firebase started using Java 9 but my project is currently working with Java 8. I tried changing the version to 9 but I get this error:

Could not target platform: 'Java SE 9' using tool chain: 'JDK 8 (1.8)'.

推荐答案

这是 Android Gradle中的错误插件，现已在 Android Studio 3.6 中修复.它似乎仅在Windows上是一个问题，因为路径格式使用反斜杠\而不是正斜杠/.我确认我可以在Linux上的Android Studio 3.5上构建我的应用程序，但不能在Windows上构建.

This is a bug in the Android Gradle plugin, fixed now in Android Studio 3.6. It looks to only be an issue on Windows, as the path format uses the backslash \ instead of forward slash /. I confirmed I am able to build my app on Android Studio 3.5 on Linux, but not Windows.
