java - JUnit AntClassNotFoundException

Question

我在运行“ant test”目标时收到 ClassNotFoundException。 所有路径和库都存在，包括位于 lib 文件夹中的 junit-4.8.1.jar。

Answer 1

我认为问题在于您将 junit 指向源文件而不是已编译的类文件。此外，文件集 包含 *Test*.java 而它应该包含 *Test*.class

尝试用这个替换你的 batchtest 元素:

<batchtest fork="yes" todir="${target-test-reports}" >
    <fileset dir="${target-test-classes}">
        <include name="**/*Test*.class"/>
    </fileset>
    <formatter type="xml"/>
    <formatter type="plain" usefile="false" />
</batchtest>
