Ant JUnit 作业无法运行 Spring 的测试 - 找不到 Spring 类运行器

Question

我有一个带有 Ivy 依赖管理库的 Eclipse Spring 项目（本地缓存中有 jars）。我写了一些带有@RunWith(SpringJUnit4ClassRunner.class) 注释的JUnit 测试类，我可以在Eclipse 中毫无问题地运行它们。不幸的是，我不能将它们作为 Ant 作业运行。我得到以下异常：

Type org.springframework.test.context.junit4.SpringJUnit4ClassRunner not present

看起来 Ant 没有将 Ivy 的缓存放入类路径中。我什至尝试将常春藤缓存的目录放入类路径，但没有结果。我该做什么？

我的常春藤依赖：

<dependencies>
    <dependency org="org.springframework" name="spring-core" rev="3.2.8.RELEASE"/>
    <dependency org="org.springframework" name="spring-jdbc" rev="3.2.8.RELEASE"/>  
    <dependency org="org.springframework" name="spring-tx" rev="3.2.8.RELEASE"/>
    <dependency org="org.springframework" name="spring-test" rev="3.2.8.RELEASE"/>
    <dependency org="mysql" name="mysql-connector-java" rev="5.1.29"/>
    <dependency org="junit" name="junit" rev="4.11"/>
</dependencies>

还有我的 Ant 构建文件：

<?xml version="1.0"?>

            </batchtest>
        </junit>
    </target>

Answer 1

试试这个：

<junit printsummary="yes" haltonfailure="yes">
    <classpath>
      <dirset dir="${user.home}/.ivy2/cache">
        <include name="**" />
      </dirset>
      <path refid="ivy.classpath"/>  <!-- ivy.classpath is already a path -->
      <pathelement location="${dir.classes}"/>
      <pathelement location="${dir.classes.tests}"/>
    </classpath>

    <batchtest fork="yes">
      <fileset dir="junit">
        <include name="**/*Test.java"/>
      </fileset>
    </batchtest>
</junit>

“ivy.path”已经是路径，所以通过引用传入。
