google Cloud spanner java.lang.IllegalArgumentException: Jetty ALPN/NPN has not been properly configured - hadoop

Question

I am new to the Google cloud Spanner and to explore it I started with documentation provided by google Here. To explore any database we start with data operations and the same I did, I started with writing data to the spanner using simple java application given here https://github.com/GoogleCloudPlatform/java-docs-samples/blob/master/spanner/cloud-client/src/main/java/com/example/spanner/SpannerSample.java. I have made changes in driver class on respective places shown in following code snippet:
public static void main(String[] args) throws Exception {
String path = "File_Path";
SpannerOptions.Builder options = SpannerOptions.newBuilder().setCredentials(GoogleCredentials.fromStream(new FileInputStream(path)));
options.setProjectId("Project_id");
Spanner spanner = (options.build()).getService();
try {
DatabaseId db = DatabaseId.of("project_id", "spannerInstance", "Database_name");
DatabaseClient dbClient = spanner.getDatabaseClient(db);
run(dbClient);
} finally {
spanner.closeAsync().get();
}
System.out.println("Closed client");
}
Now, When I am trying to execute the code I end up with following error:
Exception in thread "main" java.lang.IllegalArgumentException: Jetty ALPN/NPN has not been properly configured.

while searching for this issue I have been suggest to add some dependencies like:
compile group: 'org.eclipse.jetty.alpn', name: 'alpn-api', version: '1.1.3.v20160715'
compile group: 'org.mortbay.jetty.alpn', name: 'jetty-alpn-agent', version: '2.0.6'
compile group: 'io.grpc', name: 'grpc-all', version: '1.2.0'
compile group: 'io.netty', name: 'netty-all', version: '4.0.29.Final'
compile group: 'org.eclipse.jetty.orbit', name: 'javax.servlet', version: '3.0.0.v201112011016'
but facing same issue, I am also using Bigquery and other GCP's feature one same working environment and they all are working fine except google-Spanner, any suggestion on this is appreciated. Thanks.

Please read the comments on the question, #Mairbek Khadikov and my discussion on this conclude the actual reason of the issue. As discussed in comment the actual problem was with another dependencies.
By adding
configurations {
compile.exclude module: 'netty-all'
}
to the build.gradle file this issue has resolved.
Here is the link of github issue I raised regarding to this error. github issue where I posted exact issue eventually which I got to know and the resolution of that by, '#michaelbausor'.
