struggling to create dependencies in java for IBM speech to text

I know this is ridiculous , but I have been struggling to move on from step 0 which is to create dependencies for the project!
I want to to make a simple speech to text app that can transcribe a file for me .
How the code will look like :
package com.ibm.watson.speech_to_text;
import com.ibm.cloud.sdk.core.http.HttpMediaType;
import com.ibm.cloud.sdk.core.security.Authenticator;
import com.ibm.cloud.sdk.core.security.IamAuthenticator;
import com.ibm.watson.speech_to_text.v1.SpeechToText;
import com.ibm.watson.speech_to_text.v1.model.RecognizeOptions;
import com.ibm.watson.speech_to_text.v1.model.SpeechRecognitionResults;
import java.io.File;
import java.io.FileNotFoundException;
/**
* Recognize a sample wav file and print the transcript into the console output.
* Make sure you are using UTF-8 to print messages; otherwise, you will see
* question marks.
*/
public class Main {
public static void main(String[] args) throws FileNotFoundException {
Authenticator authenticator = new IamAuthenticator("-key");
SpeechToText service = new SpeechToText(authenticator);
File audio = new File("C:\\Users\\User\\Desktop\\curl\\test.mp3");
RecognizeOptions options = new RecognizeOptions.Builder().audio(audio).contentType(HttpMediaType.AUDIO_MP3)
.build();
;
try {
options = new RecognizeOptions.Builder().audio(audio).contentType(HttpMediaType.AUDIO_MP3).build();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
SpeechRecognitionResults transcript = service.recognize(options).execute().getResult();
System.out.println(transcript.toString());
}
}
According to github and IBM website You are supposed to create dependencies using maven or Gradle for your project and I have no idea how to do that !
I Don't understand how to create dependencies , Do I have to create a new file in the project and call it pom.xml and paste the text and run it as maven install (because that didn't work for me ) or what exactly should I do ? Please help as it's been almost 3 days and I'm struggling in like step 0!
Update:
I got these Errors when I click maven build with the goal as "clean install"

You need to create a maven project for this where its structure might look like this
my-app
|-- pom.xml
`-- src
|-- main
| `-- java
| `-- com
| `-- ibm
| `-- watson
| `-- speech_to_text
| `-- Main.java
src, main, java, com, ibm, watson, speech_to_text are the directories.
The content of the pom.xml might look like
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.ibm.watson</groupId>
<artifactId>my-app</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>com.ibm.watson</groupId>
<artifactId>ibm-watson</artifactId>
<version>9.2.0</version>
</dependency>
</dependencies>
</project>
This includes your dependencies,
After this, you need to have maven installed in your machine to compile and run it. After installing maven you can run
mvn clean install OR mvn package
to compile/build the project. This will create a JAR file for you.
Finally, you can run the project with
java YOUR_JAR_NAME.jar
Suggestions:
Don't use the package com.ibm.watson.speech_to_text in your java file instead use your own e.g. com.mycompany.app so your directory structure will also change as per the package name i.e.
my-app
|-- pom.xml
`-- src
|-- main
| `-- java
| `-- com
| `-- mycompany
| `-- app
| `-- Main.java
pom.xml content will also change according to this
<groupId>com.mycompany.app</groupId>

Can someone point me if I am missing something?
Thanks.

Your dependencies are defined inside of the < dependencyManagement > section. In this section it defines dependencies in a parent project and allows the same version to be used in sub-modules. If you remove the < dependencyManagement > tags and/or add the same thing in just < dependencies > and it should work properly.
See maven dependency management page for more details.

I have tried to upgrade Hibernate but it didn't help

Check if you have marked any dependency as a runtime dependency. Try changing the scope to compile.

play13-app-default-parent:1.0.0-beta7 depends on play 1.3.0-RC1. This version of Play! does not contain validation-api in it's dependencies, it was added in 1.3.0-RC2 but neither 1.3.0-RC2 nor 1.3.0-RC3 were deployed to Maven central. 1.3.0 was deployed.
Next version of play13-app-default-parent will depend on 1.3.0.
For now you have to add one project property to switch to 1.3.0:
<properties>
...
<play.version>1.3.0</play.version>
</properties>
