运行ant junit的时候抛出ClassNotFoundException [英] ClassNotFoundException when running ant junit
本文介绍了运行ant junit的时候抛出ClassNotFoundException的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我运行到这个的ClassNotFoundException 问题下面运行的的Junit 任务的时候，但是这是从运行命令Ant构建非基于eclipse的项目提示，构建文件下面粘贴。唯一的例外是在下面。我做了类似的设置<一的href=\"http://stackoverflow.com/questions/24830303/classnotfoundexception-when-running-ant-junit\">here它不工作虽然，任何指针将是AP preciated。谢谢。

结果= utils.getPONPortNumber（N10-1-2-3）;
assertTrue（预计3，却得到了+结果+，result.equals（2）中的结果。）;
}
}
解决方案
问题是对于src.dir 您已经定义
＆LT;属性名=src.path值=$ {} project.local.directory / SampleUnitTest / COM/＆GT;
您所创建的类是在包COM ，表示将使用被引用的类 com.SampleTest
为了解决这个异常，你需要添加一个src文件夹并移动 COM / Test.java 到该文件夹，使上述定义的 src.path 会像
＆LT;属性名=src.path值=$ {} project.local.directory / SampleUnitTest / src目录/＆GT;
，改变 MyProject.classpath 在构建XML如下
＆LT;路径ID =MyProject.classpath＆GT;
＆LT; pathelement位置=$ {} lib.path /ant-junit.jar/＆GT;
＆LT; pathelement位置=$ {} lib.path /junit.jar/＆GT;
＆LT; pathelement位置=$ {} lib.path /SampleUnitTest.jar/＆GT;
＆LT; pathelement位置=$ {} project.local.directory / SampleUnitTest /目标/＆GT;
＆LT; /路径＆GT;
I'm running into this ClassNotFoundException issue when running Junit task below, but this is non eclipse based project running an ant build from command prompt, the build file is pasted below. The exception is below. I have done similar to that of setup here it does not work though, any pointers will be appreciated. Thanks.

解决方案
Problem is the src.dir you have defined
<property name="src.path" value="${project.local.directory}/SampleUnitTest/com"/>
The class you have created is in package com that means the class will be referenced using com.SampleTest
In order to fix this anomaly you need to add a src folder and move your com/Test.java to that folder so that the above defined src.path will be like
<property name="src.path" value="${project.local.directory}/SampleUnitTest/src"/>
And also change MyProject.classpath in build xml as below
<path id="MyProject.classpath">
<pathelement location="${lib.path}/ant-junit.jar" />
<pathelement location="${lib.path}/junit.jar" />
<pathelement location="${lib.path}/SampleUnitTest.jar" />
<pathelement location="${project.local.directory}/SampleUnitTest/target"/>
</path>
