Supplied javaHome must be a valid directory. You supplied: C:\Program Files\Java\jdk1.8.0_241

Question

I got this error message when I build ionic cordova for android:

Supplied javaHome must be a valid directory. You supplied: C:\Program Files\Java\jdk1.8.0_241

The problem is that path is different from what I have JAVA_HOME variable:

Any suggestion?

Answer 1

Open the CMD Command Prompt using Administrator privilege and check the value of the JAVA_HOME variable:

echo %JAVA_HOME%

The result should be the path to the JDK installation:

C:\Program Files\Java\jdk1.8.0_202

So, if the java version is a different version, you can set the correct one:

setx -m JAVA_HOME "C:\Program Files\Java\jdk1.8.0_241"
setx -m PATH "%PATH%;%JAVA_HOME%\bin";

Just do adjusts on the Java version as you need to correct the differences. Be sure you have the installed version that you are trying to set up.

The another solution is to clean the Gradle build cache.

gradlew cleanBuildCache

Answer 2

Step 1: download and install new jdk on different location and update the JAVA_HOME path.

Step 2: make sure to add bin folder path under path Environment variable, refer below picture.
