Can't run on win10, An error occurred: java.lang.ClassNotFoundException

I am running Elasticsearch on Windows 10, and I have performed the following operations:

C:\Users\Win10\Desktop\elasticsearch-8.15.0\bin>

Elasticsearch seems unable to start.

I also ran the following code to check the Java environment variables:

C:\Users\Win10\Desktop\elasticsearch-8.15.0\bin>echo %JAVA_HOME%
C:\Program Files\Java\jdk-22

C:\Users\Win10\Desktop\elasticsearch-8.15.0\bin>java -version
openjdk version "17.0.5" 2022-10-18
OpenJDK Runtime Environment OpenLogic-OpenJDK (build 17.0.5+8-adhoc..jdk17u)
OpenJDK 64-Bit Server VM OpenLogic-OpenJDK (build 17.0.5+8-adhoc..jdk17u, mixed mode)

I hope Elasticsearch can start normally.

Added windows and removed docker

Hi @cco Welcome to the community.

Try going up 1 directory and run the command correctly as shown here

C:\Users\Win10\Desktop\elasticsearch-8.15.0> .\bin\elasticsearch.bat

Running from the correct relative Directory is important.

I would look at the docs closely and follow the directions carefully.

Damn it, this is my fault. But even after following the documentation, Elasticsearch still seems unsatisfied:

I have already deleted and re-extracted elasticsearch-8.15.0.

Do you have some java class path defined? I would try minimum env variables
