标签：build-xml java gwt command-prompt ant

我是Ant和GWT的初学者,我正在GWT中创建一个新的Ant项目,遵循GWT页面上提到的步骤：创建一个Ant项目部分下的webAppCreator.我能够成功创建这个项目,但我得到错误build.xml不存在！在命令提示符日志中.即使遵循此处提到的所有步骤,我也无法解决此问题：ant build.xml file doesn’t exist.

这是我的命令提示符日志：

C:\Users\TEST>ant build

这是我的build.xml文件：

有人可以帮我解决这个问题吗？

解决方法:

看来你的build.xml是在foo文件夹中创建的.
看到这个输出：

Created file foo\build.xml

转到foo目录然后运行ant.
