运行运行目标时Ant生成错误

Question

我使用ant 1.9.0来运行我的Java项目。我有一个bat文件，其中有命令ant clean compile运行。clean and compile正在运行，但对于目标运行，我得到的错误

 C:UsersSusantaMyMavenMyMavenProjectbuild] on class org.apache.
 tools.ant.taskdefs.optional.junit.XMLJUnitResultFormatter: java.lang.NoClassDefFoundErrorjunit/framework/TestListener

我正在附加build.xml，请让我知道我的build.xml 中的问题

Answer 1

这似乎是ANT 1.9.0中的已知错误。请参阅此处：运行junit任务时，Bamboo Ant任务失败

阅读comments #4, #5, #8 & #20@THIS链接以获得一些帮助。

Answer 2

ANT手册描述了junit任务如何需要额外的jar。这可以从Maven Central 下载

• junit版本列表

并安装在以下目录中：

• $HOME/.ant/lib

就我个人而言，我使用一个名为ivy的ANT插件来管理我的构建依赖关系，请参阅：

• 在build.xml中找不到包含Ant、Ivy和JUnit的类-错误
• 在netbeans中使用Ant在构建期间动态获取外部库的最新版本

Answer 3

查看您的错误消息：

C:UsersSusantaMyMavenMyMavenProjectbuild] on class  
    org.apache.tools.ant.taskdefs.optional.junit.XMLJUnitResultFormatter: 
    java.lang.NoClassDefFoundError junit/framework/TestListener

注意NoClassDefFoundError，这意味着Ant找不到您的任务所引用的类。是否有与此错误相关的行号？应该有一个指向包含<junit/>任务的行。即使没有它，您也可以看到未找到的类是junit/framework/TestListener。

Java应用程序中的错误消息可能有点吓人，因为您可以看到数十行，甚至数百行的堆栈跟踪。然而，将Java程序崩溃视为一场车祸。一辆车可能从路上倾斜，撞上了电线杆，从电线杆上弹了回来，撞上另一辆车，从电线上弹了出来，撞倒了消防栓，等等。你可以看到很长的损坏痕迹，但如果你看看事故发生的第一个地方，你通常可以看到问题所在(看，路上有香蕉皮！(

Java错误消息也是如此。第一行通常会准确地告诉你需要知道什么，例外情况很容易阅读。在这种情况下，NoClassDefFoundError和它指出junit是罪魁祸首。下次你看到这样的东西时，你就会知道该找什么了。

---

正如Mark O’Connor所指出的，JUnit任务所需的jar不包含在Ant中。事实上，正如您在该表中看到的那样，许多定义的任务都没有运行这些任务所需的jar(<junit>是该表中的第四项(。

在关于JUunit任务的Ant手册中，它指出您可以执行以下操作：

注意：您必须有可用的junit.jar。您可以执行以下操作之一：

1. 将junit.jar和ant-junit.jar都放在ANT_HOME/lib中
2. 不要将两者都放在ANT_HOME/lib中，而是将它们的位置包含在CLASSPATH环境变量中
3. 使用-lib将两个JAR添加到类路径中
4. 使用生成文件中<taskdef>中的<classpath>元素指定两个JAR的位置
5. 将ant-junit.jar保留在ANT_HOME/lib中的默认位置，但将junit.jar包括在传递给的中。(自Ant 1.7以来(

我个人更喜欢最后一个。我通常把junit.jar放在${basedir}/antlib/junit中。这样，当有人检查我的项目时，他们会得到junit

在Ant常见问题解答中，它讨论了<junit>的一些问题。
