【问题描述】：
现在我在我的项目中使用 GWT 1.7，我需要升级到 GWT 2。我还有：
GXT 2.0.1 Maven 2.2.1 gwt-maven-插件 1.1 maven-compiler-plugin 2.0.2（它的源和目标配置是1.6）
所以我已经将 GWT 版本更改为 2.0.4，但我的 GXT 版本似乎与它不兼容。我发现的 GXT 的最低版本是 2.2.5，但有了它我的项目看起来……很奇怪 :) 那么，它有旧的兼容版本吗？
而且我的 maven 也不适用于新的 gwt。我尝试了不同版本的 gwt-mavten-plugin，它们都抛出了不同的错误。也许我必须使用不同的 maven 或 maven-compiler-plugin？
更新
GWT：2.0.4，GXT：2.2.5，gwt-maven-plugin 2.1.0，maven-compiler-plugin 2.1
项目在 Idea 中构建，但是当我运行 mvn clean install 时：

【问题讨论】：
-
一个问题，呃，请提问；并显示您认为正确的 gwt/gwt-maven-plugin 组合的错误。
-
好的，我做到了，看看上面的错误
-
[WARNING] You're project declares dependency on gwt-user 2.0.4. This plugin is designed for version 2.1.0是什么让您认为这是正确的组合？ （顺便说一句，2.0.4 已经很老了——尽管比 1.7 还早——你不能升级到最新/体面的 GWT 版本吗？） -
我还没有找到 gwt 2.0.4 的 gwt-maven-plugin。我会尝试将 gwt 升级到 2.1，但我知道兼容性，因为项目真的很大，我不希望它完全崩溃。
-
gwt-maven-plugin 1.2 should work 与 GWT 2.0.4。从 2.1 开始，gwt-maven-plugin 是针对特定版本的 GWT 构建并兼容的，因此切换到相同的版本控制方案。
