Java 无法使用ant运行GWTTestCase测试

我根本无法成功运行

gwtsetcase

测试。我使用的是

gwt2.6.1

，

junit4.11

，

ant1.8.2

。我已经创建了一个示例

Ant target运行测试（这里可能有一些明显的问题）：

---

你知道我做错了什么吗？我也尝试过JUnit3.8，但没有帮助。可能缺少

*jar

文件或版本不正确？

好的，我设法用

Ant

运行了

gwtsetcase

测试。示例项目正在进行中

首先，我切换到了

junit

taskfork模式。正如上面所说

一般来说，建议分叉一个新的虚拟机，因为它将您的测试与Ant的环境隔离开来（在类加载器上包含很多库，特别是与XML相关的类），但是由于启动新Java虚拟机的巨大开销，它变得非常慢

然后，当我添加

验证api

包（

ivy.XML

）时，在处理XML时，我设法得到了比这个

[ERROR]意外错误更多的详细错误：

最后，我不得不将测试模块路径添加到测试类路径（
build.xml
）：
