无法编译Atmosphere客户端

Question

我正在尝试使用GWT创建Atmosphere客户端。我添加了

atmosphere-annotations-2.4.3.jar
atmosphere-gwt20-client-2.4.2.jar
atmosphere-gwt-common-2.4.2.jar
atmosphere-runtime-2.4.3.jar

添加到buildpath，插入

<inherits name="org.atmosphere.gwt20.AtmosphereGwt20"/>
<inherits name='com.google.gwt.core.Core'/>
<inherits name="com.google.web.bindery.autobean.AutoBean"/>

到projectname.get.xml

我尝试向服务器发起呼叫，如下所示

GwtRpcClientSerializer rpc_serializer = GWT.create(GwtRpcClientSerializer.class);
// or
// RPCSerializer rpc_serializer = GWT.create(RPCSerializer.class);

AtmosphereRequestConfig jerseyRpcRequestConfig = AtmosphereRequestConfig.create(rpc_serializer);
jerseyRpcRequestConfig.setUrl(GWT.getHostPageBaseURL() + "it/more/atmosphere");
jerseyRpcRequestConfig.setTransport(AtmosphereRequestConfig.Transport.WEBSOCKET);
jerseyRpcRequestConfig.setFallbackTransport(AtmosphereRequestConfig.Transport.STREAMING);

在GWT编译中，我得到了

或

[java]    [WARN] For the following type(s), generated source was never committed (did you forget to call commit()?)

我遵循了GWT的示例代码。我遗漏了什么？

Answer 1

该项目似乎在GWT2.7中出现了问题。在某个地方，我找到了使用客户端jar版本2.3.2-get27编译它的建议，并且它可以使用jar

atmosphere-annotations-2.4.3.jar
atmosphere-gwt20-client-2.3.2-gwt27.jar
atmosphere-gwt20-common-2.3.2-gwt27.jar
atmosphere-runtime-2.4.3.jar

而且只有

<inherits name="org.atmosphere.gwt20.AtmosphereGwt20"/>

projectname.gwt.xml内幕

目前我面临的问题是

Atmosphere atmosphere = Atmosphere.create();

它仍然是null，但这是另一件需要考虑的事情(我想)。
