我正在尝试使用embeded api在我的java程序中嵌入glassfish，我使用的是maven2，它的pom.xml如下所示

程序：
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();
}
}
但由于某种原因，它总是给我错误java.lang.NoClassDefFoundError: java/util/ServiceLoader
这是输出
C:\Users\sunils\glassfish-tests\glassfish-test1>mvn -e exec:java
+ Error stacktraces are turned on.
