How to solve Flutter could not find tools.jar?

Solution 1: add your jdk path

I Think Some Problem with JDK path That’s Why facing This Error. So lets solve this error by all possible ways.

1. Go to your android folder > Gradle.properties > add your jdk path.

2. Clean and rebuild then it is done.

// For Example Purpose Only
org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk1.8.0_251.jdk/Contents/Home

Solution 2: JAVA_HOME variable was not set

Problem Is the JAVA_HOME variable was not set (or Big Sur removed it somehow).

So we simply added it in my ~/.zshrc (or ~/.bashrc)- profiles

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home

You can simply check and replace the version number in the above line.

Solution 3: Add jdk path

At last, here I found the solution.

Add jdk path

org.gradle.java.home=YOU_PATH_TO_JDK

to gradle.properties file and did a rebuild.

This Will Also Solve Your error.
