Cordova picking up wrong version of java

I am trying to run

cordova build android

It gives the following error

Checking Java JDK and Android SDK versions
ANDROID_SDK_ROOT=/home/bappaditya/Softwares/android-studio (recommended setting)
ANDROID_HOME=/home/bappaditya/Softwares/android-studio (DEPRECATED)
Requirements check failed for JDK 8 ('1.8.*')! Detected version: 12.0.2
Check your ANDROID_SDK_ROOT / JAVA_HOME / PATH environment variables.

I can see that it has picked up ANDROID_HOME and ANDROID_SDK_ROOT but not the correct version of java

My current environment

>java -version
openjdk version "1.8.0_275"
OpenJDK Runtime Environment (build 1.8.0_275-8u275-b01-0ubuntu1~20.04-b01)
OpenJDK 64-Bit Server VM (build 25.275-b01, mixed mode)

>echo $JAVA_HOME
/usr/lib/jvm/java-8-openjdk-amd64

>echo $PATH
/home/bappaditya/.cargo/bin:/opt/gradle/gradle-5.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/bappaditya/bin:/usr/lib/jvm/java-8-openjdk-amd64/bin

As you can see the JAVA 8 is installed and set as default. Why cordova complaining about java version?

It seems cordova uses javac to identify the version and not java.

So the command that really shows the version cordova gets when looking for Java is:

javac -version

In my case, even though I had identical versions to what you have in your environment, it turned out my javac was pointing to a newly updated Java (from Ubuntu updates)

To fix it, I used the update-alternatives command and set javac back to my 1.8.0 version as follow:

sudo update-alternatives --config javac
