提供的 javaHome 似乎无效。 我找不到 java 可执行文件。 试过位置：C:\Program Files\Java\jdk-17\bin\java.exe

Question

I've been pulling my hair over this for 3 days now,

every time I run the command react-native run-android I get this error:

info Running jetifier to migrate libraries to AndroidX. You can disable it using "--no-jetifier" flag.
(node:10284) Warning: Accessing non-existent property 'padLevels' of module exports inside circular dependency
(Use `node --trace-warnings ...` to show where the warning was created)

I created my directory using basic react-native init projectTesting

My gradle is version 6.9
.\android\gradle\wrapper\gradle-wrapper.properties => distributionUrl=https\://services.gradle.org/distributions/gradle-6.9-all.zip

My android studios version is Android Studio 2020.3.1

My java version is 15

C:\Users\username>java -version
java version "15" 2020-09-15
Java(TM) SE Runtime Environment (build 15+36-1562)
Java HotSpot(TM) 64-Bit Server VM (build 15+36-1562, mixed mode, sharing)

C:\Users\username>javac -version
javac 15

I was thinking of using java 17 but in the compatibility docs it said:

A Java version between 8 and 15 is required to execute Gradle. Java 16 and later versions are not yet supported when executing Gradle.

any help would be really really appreciated!!
