Ant-Junit-eclipse-build.xml-java.lang.ClassNotFoundException错误

我是Ant的新手，获得java.lang.ClassNotFoundException。但是，当从eclipse/Ant build.xml运行Junit时，当从eclipse单独运行单元测试时，测试通过，没有问题。我的类路径应该有一些问题，我无法解决

我的环境是：

Java_home:C:/ProgramFiles/Java/jdk1.7.0_25 Ant_home:C:/Users/Armen/javaFolder/apache-Ant-1.9.2/bin JUnit_home:C:/Users/Armen/javaFolder/apache-ant-1.9.2/bin/JUnit-4.10.jar

My Build.xml

在此处输入image description

您的构建脚本中没有编译单元测试的任何步骤，并且当您告诉JUnit运行时，您也不会在类路径中包含编译后的类—只有源文件

因此，您需要做两件事：

添加一个类似于以下内容的额外构建步骤

<target name="test-compile" depends="compile">
    <javac includeantruntime="false" srcdir="./test" destdir="./test-classes" />
</target>

注意在编译和运行步骤中，不清楚您的代码是在Java包中正确构造的，还是在包中正确构造的，您是否理解这些代码是如何工作的。我假设您的代码位于

demo

包中，因此将该部分路径从编译的类位置中剥离出来。

哪个类NotFoundException？检查类并在类路径中找到相同的jar文件？
