Question

I am getting the following error – I have added the GSon in my dependency –

Can someone point out what I am doing wrong?

Edit : dependency specified –

   <dependency>
        <groupId>com.google.code.gson</groupId>
        <artifactId>gson</artifactId>
        <version>1.7.1</version>
    </dependency>

I am using the following code in my sevlet –

 JSONService json = new JSONService();
    String json_output = json.makeLoginJSON(user);

makeLoginJSON —

   public String makeLoginJSON(LoginDetails user) {
    String FinalJson = null;
    Gson gson = new Gson();
    FinalJson = gson.toJson(user);      
    return FinalJson;       
}

Try:

<dependency>
        <groupId>com.google.code.gson</groupId>
        <artifactId>gson</artifactId>
        <version>2.1</version>
        <scope>provided</scope>
</dependency>

I have edited my comment and added the scope. The default scope is compile, meaning that the dependency is not present at runtime. For this, you use the provided scope. More about scopes in maven dependencies on Apache’s Introduction to Maven Dependencies.

Hope this resolves your issue.

P.S.: if you are creating your own repository, you should also take a look here.
