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

1. `codeql database create java_db1 --language=java --source-root Java/
3. Initializing database at /home/prakash/java_db1.
4. Running build command: [/home/prakash/codeql/java/tools/autobuild.sh]

7. 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](url)
Anyone can help ASAP?
