更新#2： SpringRoo 的男孩们将责任推给了 Google 的男孩们。看这里的票。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。他们已将优先级从次要升级为关键。请参阅此处的问题。

大家好，

我能够按照 SpringRoo 页面上的迷你教程让 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，我决定使用 GWT 进行尝试。我认为这就像从 Roo shell 运行命令一样简单gwt setup，但事实并非如此。当我运行项目时，我注意到该命令将创建文件（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.

对 Roo 和 GWT 不太了解，我还是运行了这个mvn gwt:run命令，只是想看看它是否可以工作。好吧，毫不奇怪，它没有。

我为该mvn gwt:run命令找到了以下 JIRA 问题，但它不起作用。我确信在第一个问题解决之前它不会起作用http://jira.codehaus.org/browse/MGWT-57

补充： MGWT-57 说尝试 mvn clean gwt:run。我做了并尝试运行 mvn gwt:run 无济于事 - 相同的错误消息。MGWT-57 还说要移动一些节点，尽管我必须承认我不知道它们指的是什么节点。但是，我确实搜索了错误消息中gwt-maven-plugin的节点runTarget，但在我的 pom.xml 中找不到它们。我认为这很奇怪，并推断这可能是因为运行时的第一个问题gwt setup。

我很难为第一个问题找到任何东西，gwt setup在 Roo shell 中运行命令，这就是我在这里的原因。

有任何想法吗？

我已经包含了下面两个命令的输出。

我在这里先向您的帮助表示感谢！

这里同样的问题。我是 SpringRoo 的新手，只是想用一些字段创建两个简单的实体，但 gwt:run 命令一直失败。感谢您发布它（这只是我找到的相关信息）并报告问题。

几天前我用 GWT 尝试了比萨店，它奏效了。在具有 java 1.6、maven 2.2 的 linux 机器上进行了测试。这可能没有多大帮助，但至少它以某种方式起作用。如果您喜欢可以上传一个包含整个项目的 zip 文件，您可以使用 gwt 运行该文件。
