I have added gson to my pom.xml . Here is it. But when I call Gson gson = new Gson() and try so search in maven repository it doesn't found any element. Why? Where do I wrong?

                what does mean "is not found"? do you receive a Maven error? in this case, show us this error.

                for it to be found in the maven repository you should run maven clean install first time when you add a new library to you pom file

                I'm working on netbeans. In my java file I write Gson gson = new Gson(). then I click to the right in "Search dependencies in Maven repository..." but when the dialog window open it show me "No matching result"

Kindly add this to your pom.xml file under project This would tell maven to download the libraries you include in the pom file from here:
<repositories>
    <repository>
      <id>central</id>
      <name>Maven repository</name>
      <url>http://repo1.maven.org/maven2</url>
    </repository>
  </repositories>
And your code will be something like this:
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
Gson gson = new GsonBuilder().create();
And consult this guide on how to use Gson in case you need help using it too.
                I have the same problem as OP but in Eclipse. This works but I just can't get any auto-completion. Can this be related to Gson itself?

                Struggled with this for a few hours until I found this post.  I know it's a couple of years old but it still applies, at least to some Eclipse distributions.
