gwt - ant gwt 编译器任务失败

Question

我正在关注这个 tutorial创建 java 编译的 ant 构建文件，而不是 GWT 编译，然后执行正确的操作来构建我的 .war 文件。
我使用 Eclipse 和 GWT-compile 工作，当我运行开发模式时它工作。我也成功部署在tomcat上。
事情是当我运行我的脚本时，编译工作但它在 gwt-compiler 任务上失败。我的 Ant 构建脚本如下:

<project name="vlp" default="gwt.compile" basedir=".">

我发现将 gwt-compiler 类名更改为 DevMode 正在成功构建。使用: classname="com.google.gwt.dev.DevMode"而不是 classname="com.google.gwt.dev.Compiler" .
编辑:我重构了上面的 XML。
build.xml 清除所有 bin 目录。我也指向了 javac到 bin/src目录和 Google Web Toolkit 编译器输出到: bin/gwt .编译器还是不行...
编辑:我立即从 google 开发人员站点下载了最新的 SDK，并覆盖了在我的类路径和我的 eclipse 插件中找到的旧库。仍然无法使用 ant 构建脚本。
有人看到这里可能有什么问题吗？

Answer 1

我只能说这个方法com.google.gwt.dev.jjs.ast.JProgram.serializeTypes(Ljava/util/List;Ljava/io/ObjectOutputStream;)V仅在 gwt-dev 2.4.0 中引入.它不存在于 gwt-dev 2.3.0 .

这意味着在类路径中的某个地方有两个 gwt-dev 版本。其中之一是 2.4.0，这就是为什么 com.google.gwt.dev.javac.CompilationUnitImpl正在寻找那个方法。另一个是 2.3.0 或更旧的版本，这就是为什么找不到该方法的原因(使用旧版本的编译器加载了 JProgram 类)。

尝试彻底查找它们。或者尝试创建一个全新的环境，您可以在其中密切关注正在发生的事情。
