java - JUnit 与 Ant，另一个 java.lang.ClassNotFoundException

Question

刚接触 Ant，不太知道自己在做什么。我的猜测是我没有正确设置 JUnit 类路径。我看到有很多与此类似的问题，尽管没有一个建议对我有用。请帮忙!

我的项目目录结构:(我怀疑我的目录结构严重困惑)

MyProject/
    bin/main/
        project.class
        test1.class
        test2.class
        test3.class
    build/main/project
        Project.class
    build/test/main
        test1.class
        test2.class
        test3.class
    build/test/project
        test1.class
        test2.class
        test3.class
    lib/
        junit-4.11.jar
        hamcrest-all-1.3.jar
    src/main/java/
        project.java
    src/test/java/
        test1.java
        test2.java
        test3.java
    build.xml

我的build.xml

<project name="junit-example">
  <property name="main.build.dir" value="build/main"/>
  <property name="main.src.dir" value="src/main/java"/>
  <property name="test.build.dir" value="build/test"/>
  <property name="test.src.dir" value="src/test/java"/>

  <path id="classpath.test">

    <pathelement location="lib/hamcrest-core-1.3.jar"/>
    <pathelement location="${main.build.dir}"/>
  </path>

  <target name="compile">

    <javac srcdir="${main.src.dir}" destdir="${main.build.dir}" includeantruntime="false"/>
  </target>

        </classpath>
        <formatter type="brief" usefile="false" />
        <batchtest>
            <fileset dir="${test.src.dir}" includes="**/*Test.java" />
        </batchtest>
    </junit>
  </target>
</project>

Answer 1

您将batchtest定义为

<batchtest>
    <fileset dir="${test.src.dir}" includes="**/*Test.java" />
</batchtest>

但是您的 ${test.src.dir} 中的文件是

src/test/java/
    test1.java
    test2.java
    test3.java

尝试将batchtest更改为

<batchtest>
    <fileset dir="${test.src.dir}" includes="**/*test?.java" />
</batchtest>
