无法让GWT与SpringRoo一起使用

更新＃2：在SpringRoo失意的男孩们向谷歌的男孩们致敬。查看票证here。它也被升级为关键优先级。

更新：我在SpringRoo问题跟踪器上记录了一个错误。看起来男孩们正在认真对待这件事。他们将优先级从轻微升级到关键。请参阅问题here。

大家好，

在SpringRoo页面上的迷你教程之后，我能够让GWT与SpringRoo一起工作：http://www.springsource.org/roo/start

然后我决定在这里尝试他们的其他教程：http://static.springsource.org/spring-roo/reference/html/beginning.html

完成第6步后，我决定尝试使用GWT。我认为这就像从Roo shell运行gwt setup命令一样简单，但事实并非如此。当我运行项目时，我注意到该命令会创建文件（如预期的那样），然后开始撤消它创建的文件，最后以异常结束：String index out of range: -1。

不太了解Roo和GWT，我还是运行了mvn gwt:run命令，只是为了看它是否可行。嗯，毫不奇怪，它没有。

我发现了mvn gwt:run命令的以下JIRA问题，但它没有用。我确信在第一个问题得到解决之后它才会起作用http://jira.codehaus.org/browse/MGWT-57

ADDITION： MGWT-57说要尝试mvn clean gwt：run。我做了并尝试运行mvn gwt：后来运行无效 - 相同的错误消息。 MGWT-57也表示要移动一些节点，但我必须承认我不知道他们指的是什么节点。但是，我确实在错误消息中搜索gwt-maven-plugin以及节点runTarget，但是在我的pom.xml中找不到它们。我认为这很奇怪，推断它可能是因为运行gwt setup时的第一个问题。

我很难找到第一个问题，在Roo shell中运行gwt setup命令，这就是我在这里的原因。

有什么想法吗？

我已经包含了以下两个命令的输出。

提前感谢您的帮助！

gwt setup命令的输出：

这是mvn gwt：run命令的输出：

我几天前和GWT一起尝试了这家披萨店，结果很有用。用java 1.6，maven 2.2在linux机器上测试。这可能没有多大帮助，但至少它是以某种方式工作。如果你喜欢可以上传一个zip文件与整个项目，你可以用gwt运行。
