我创建了一个示例项目来使用 gwt-test-utils ( https://github.com/povilasb/gwt-test-utils-sample ) 运行我的 gwt 测试。我正在使用 Ant (1.8.2) 进行构建，包：gwt 2.6、juni 4.11 和 gwt-test-utils 0.47。

不幸的是，我无法运行测试：

html-test-utils-config:

test:

似乎有人以前已经遇到过这个问题：https ://code.google.com/p/gwt-test-utils/issues/detail?id=168 。在那里找不到解决方案。

有人对 gwt 2.6 和 gwt-test-utils 4.7 和 ant 有好运吗？

我设法解决了我的问题。我消除了错误

扫描包“com.googlecode.gwt.test.internal.patchers”时出错

Ant junit通过在任务中使用 fork 模式：

<junit haltonfailure="false" includeantruntime="false"
    fork="yes" forkmode="once" >

这是运行测试的推荐方法：junit

一般来说，建议使用 fork 一个新的 VM，因为它将您的测试与 Ant 的环境（其中包含类加载器上的许多库，特别是 XML 相关的类）隔离开来，但是由于与启动新的 Java VM 相关的大量开销，它变得非常慢.

在此之后我有另一个错误：

我通过将源代码目录添加到junit类路径解决了这个错误：

<property name="src.dir" value="src" />
...
<junit haltonfailure="false" includeantruntime="false"
    fork="yes" forkmode="once" >
    ...
    <classpath>
        <path refid="project.class.path" />
        <pathelement location="${test.build.dir}" />
        <pathelement location="${src.dir}" />
    </classpath>

    ...
</junit>

我猜 gwt-test-utils 需要 gwt 模块的来源。您可以在github上找到完整工作的示例项目。
