问题：

GWT超级开发模式不编译最新的源代码

贺华容

2023-03-14

我有一个使用GWT2.7.0的GWT项目，并且正在使用Maven。该应用程序正在正确编译和运行，然而，我正在努力使GWT的超级开发模式正常工作。当我用

mvn gwt:run-codeserver

超级开发模式正确启动，编译，最新的更改显示在浏览器中。但是，当我按compile bookmarklet重新编译GWT代码时，重新编译正确完成，浏览器刷新，但不包括我对客户机/GWT java文件所做的任何后续更改。

当启动GWT Super Dev模式时，它似乎将源文件（.java文件）从src/main/java复制到Maven的构建文件夹(target)，并且它似乎是从目标文件夹中的源文件编译，而不是从src/main/java中的源文件编译。我已经测试了这一点，方法是手动将一个我修改过的java文件从src/main/java复制到目标文件夹中，然后点击compile bookmarklet。当我这样做时，重新编译会像以前一样成功，并显示最新的更改。

我假设我错过了将src/main/java复制到目标文件夹的配置，或者我错误地配置了Super Dev模式，在目标文件夹应该从src/main java源代码编译时从目标文件夹编译

任何帮助，以了解它应该如何运作和解决这一点，将不胜感激。

从GWT2.7开始，应该设置launcherdir属性以在重新加载时获得重新编译。该属性应该指向一个文件夹，您的web服务器/servlet容器将在该文件夹中查找web资源，以便由CodeSever生成的*.nocache.js文件可以由您的web浏览器加载。
