[BUG] Git Bash can't run ./bin/opensearch command.

[davidosorno]

Describe the bug
Using Git Bash on Windows I run ./bin/opensearch and got a Java error that can't load the main class.

$ ./bin/opensearch
Error: Could not find or load main class org.opensearch.tools.java_version_checker.JavaVersionChecker
Caused by: java.lang.ClassNotFoundException: org.opensearch.tools.java_version_checker.JavaVersionChecker

To Reproduce
Steps to reproduce the behavior:

1. Using Git Bash on Windows, go to 'OpenSearch/build/distribution/local/opensearch-3.0.0-SNAPSHOT/'
2. Run ./bin/opensearch
3. See error.

Expected behavior
I expected Git Bash runs the OpenSearch project and make the localhost:9200 available.

I just thought about this, does it run when you do ./gradlew run?

[davidosorno]

Yeah, it worked.

Any idea, why did it work?

[HJohnRoss]

I also tried ./gradlew run, it did not work for me, I had some errors ill post in a edit

edit: same thing actually (I remember some run errors the first time that I had tried I am pretty sure)

Hi @HJohnRoss, I think is working. Try the following:

1. Run the command ./gradlew run and it should finish like this (don't stop or close this window).
   

2. Then go to http://localhost:9200/_cat/health and you should see something like this

It is recommended to run opensearch-windows-install.bat in the root of the Windows ZIP extracted folder, as we have a lot of setups happens there, before launching opensearch.

The opensearch-windows-install.bat is internally calling bin/opensearch.bat instead of bin/opensearch, as the latter was written with NIX* in mind afaik, not always support git bash, or even full ledge mingw/msys2. So running bin/opensearch.bat is always recommended for the Windows specific distribution.

Thanks.
