埋め込まれたAPIを使用してJavaプログラムにガラスフィッシュを埋め込もうとしています。Maven2を使用しています。POM.xmlは次のとおりです。

プログラム：
public class App
{
public static void main( String[] args )
{
System.out.println( "Hello World!" );
Server.Builder builder = new Server.Builder("test");
builder.logger(true);
Server server = builder.build();
}
}
しかし、何らかの理由で、それは常に私にエラーを与えます java.lang.NoClassDefFoundError: java/util/ServiceLoader
これが出力です

プログラムやGlassfish APIの問題は推測できませんでした。誰かがここで何が起こっているのか、それを修正する方法を理解するのを手伝ってもらえますか？
手がかりをありがとう。

このエラーは、JDKの新しいバージョンをインストールした後になくなりました:)
