Elastricsearch-2.2.0 is not starting

Elastic Stack Elasticsearch
1

I have installed elasticsearch 2.2.0 and it worked fine for a week, but now it didn't start. I have set both JAVA_HOME and JRE_HOME. I use java version 1.8 (i.e., jdk1.8.0_201 and jre1.8.0_202). When I try to start the elasticsearch.bat it terminates with a error message of:

Exception in thread "main" java.lang.NoClassDefFoundError: 
org/apache/commons/cli/CommandLineParser
Likely root cause: java.lang.ClassNotFoundException:

Refer to the log for complete error details.

But no logs has been generated.

Why are you using such an old version?

How did you install it?

Downloaded the zip file and unzipped it.

Now I found that JAVA API is working fine but the elasticsearch-2.2.0 is not starting and not running on localhost:9200
