蚂蚁build.xml不存在.构建失败

我是ANT和GWT的初学者，我正在GWT中创建一个新的ANT项目，通过遵循此GWT页面上提到的步骤：下的WebAppCreator在下创建Ant项目部分。我能够成功创建此项目，但是在命令提示符日志中，我发现了错误 build.xml！。即使在此处提到的所有步骤之后，我也无法解决此问题：ant build.xml文件不存在。

这是我的命令提示符日志：

这是我的build.xml文件：

有人可以帮我解决这个问题吗？

看来您的build.xml是在FOO文件夹中创建的。查看此输出：

创建的文件foo build.xml

转到FOO目录，然后运行ant。

c： users test＆gt; ant build

buildfile：build.xml不存在！

构建失败

这意味着TEST目录中没有构建文件。检查您的日志您在:UsersTESTfoo中有一个。因此，您应该导航到foo，而不是再通过终端尝试命令。

如果您在Mac上：

酿造安装蚂蚁;
啤酒安装常春藤;
ant Ivy-bootstrap;然后进入蚂蚁项目的顶部；运行蚂蚁
