Google app engine GWT 2.7+；GAE应用程序在部署时查找codeserver 为什么appengine尝试使用超级开发模式？

每次我将我的GWT应用程序部署到appengine并尝试访问它时，我都会看到白色的加载屏幕，大约20-30秒后，我会收到以下消息：

我将maven与and一起使用。使用部署会得到相同的结果

如果我切换回使用2.6.1版本的gwt和它部署的GWTMaven插件，那么这似乎与自动开发模式启动器有关

在my Project.gwt.xml中

（尝试删除此行，但仍然得到相同的结果）

环境 月食月神（4.4.1）

Maven 3.2.3（3.2.1嵌入式）

---

M2Eclipse1.5.0

gwt:compile

通过比较nocache.js文件的时间戳与源文件的时间戳来尝试“增量”工作，如果认为输出是最新的，则跳过gwt编译这是易碎的

gwt:run

（不带

false

；和

gwt:run codeserver

带

launcherDir

）将使用特定于SuperDevMode的版本覆盖nocache.js，这可能导致

gwt:compile

跳过编译

---

要点是：在部署或“释放”时，确保首先运行

mvn clean

或force

gwt:compile

通过将

-Dgwt.compiler.force

传递给Maven来运行。

仅供参考，我也遇到了同样的问题，这是由使用非标准项目结构引起的

Maven在不同于

/target/

的目录中复制

.nocache

文件，这阻止了

清理
插件清理生成的文件

在复制文件的目录中添加一个新的目录可以解决问题。
谢谢，但我总是先运行“mvn clean”，每次尝试都会出现这种情况。会这样吗？（但是使用由SuperDevMode而不是经典DevMode生成的nocache.js，因此行为有所不同）
