ERROR: Could not detect a suitable build command for the source checkout

[neupaneprakash]

1. `codeql database create java_db1 --language=java --source-root Java/
2. Initializing database at /home/prakash/java_db1.
3. Running build command: [/home/prakash/codeql/java/tools/autobuild.sh]
4. [2022-11-11 11:29:36] [build-stderr] ERROR: Could not detect a suitable build command for the source checkout.
5. [2022-11-11 11:29:36] [ERROR] Spawned process exited abnormally (code 1; tried to run: [/home/prakash/codeql/tools/linux64/preload_tracer, /home/prakash/codeql/java/tools/autobuild.sh])
6. A fatal error occurred: Exit status 1 from command: [/home/prakash/codeql/java/tools/autobuild.sh] `

Above log is generated while executing database create command. I was simply trying to create codeql database for java with single java file named TestClass.java inside the Java directory but I am not being able to create database successfully.
For your reference I am attaching the java source code here : https://www.dropbox.com/sh/q1t648a3imvmesk/AAAxoRWnihrO2oYiBrDQICWQa?dl=0 Anyone can help ASAP?

CodeQL analysis for Java needs to compile the Java source code in order to analyze it. The "autobuilder" is a small program that tries to automatically figure out how to build the code base. It supports common build systems like gradle, maven and ant, and also picks up simple build scripts named build.sh or build.cmd (for windows).

CodeQL does not know how to compile a single Java file. Simply calling javac SoureFile.java is unlikely to work very often in practice, because you'd normally need to add dependencies to the classpath using the -cp flag.

In your case I'd recommend adding a simple build.sh file to your repo :

#! /bin/bash

javac TestClass.java

Alternatively you can invoke codeql with an explicit build command like codeql database create java_db1 --language=java --source-root Java/ --command "javac TestClass.java"
