I was trying to run ./gradlew bootRun in both Git Bash and PowerShell, and got this error: ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jre1.8.0_121
The gradlew file is inside the project directory that cloned from git. It is a practice project from Spring official guide. There's also a gradle.bat file with these lines:
:findJavaFromJavaHome
set JAVA_HOME=%JAVA_HOME:"=%
set JAVA_EXE=%JAVA_HOME%\bin\java.exe
I also tried to run Eclipse EE, which got no problem. The environment setting should be no problem.

Right click My Computer and select Properties. On the Advanced tab, select Environment Variables, and then edit JAVA_HOME to point to where the JDK software is located, for example, C:\Program Files\Java\jdk1.
Verify JAVA_HOMEOpen a Command Prompt window (Win⊞ + R, type cmd, hit Enter). Enter the command echo %JAVA_HOME% . This should output the path to your Java installation folder. If it doesn't, your JAVA_HOME variable was not set correctly.
In addition to Ernest's answer, the JAVA_HOME it wants is the actual directory, not the bin folder like the path wants for javac. Took me a while to work that out
