The supplied javaHome seems to be invalid. I cannot find the java executable. Tried location: C:\Program Files\Java\jdk-17\bin\java.exe

Issue

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.

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!!

Solution

Make sure of your JAVA_HOME Path in your terminal with

echo %JAVA_HOME%

Its a common mistake to have \bin , while \bin should be in the PATH the java home is only your jdk folder like C:\Program Files\Java\jdk-15 .

Deleted the jdk-17 folder and then uninstalled 31 and 30 version of sdk build tools and this should fix the issue .
