Ant JUnit ClassNotFoundException

Question

我意识到这个问题有很多类似的问题,但是在阅读了大部分问题后,我似乎遇到了同样的问题,但出于不同的原因.

我正在<junit>我的Ant构建中运行一个任务,并且正在获得一个ClassNotFoundException.在大多数类似相关的问题(例如上面的问题)中,结果是作者的各种程度都没有正确配置JUnit类路径.虽然对我来说可能完全相同,但对这些其他问题的任何建议都没有对我有用.

我的项目目录结构:

MyProject/
    src/main/java/
        FakeObject.java
        ...the rest of my Java main source
    src/test/java
        FakeObjectUnitTest.java
        ...the rest of my Java test source
    bin/main
        FakeObject.class
        ...the rest of main Java binaries
    bin/test
        FakeObjectUnitTest.class
        ...the rest of main Java binaries
    lib/main
        ...my main dependencies
    lib/test
        junit-4.10.jar
        hamcrest-1.1.jar
        ...the rest of my test dependencies
    gen/reports
        ...where JUnit should be placing all test reports
    build/
        build.xml
        build.properties

在src/test/java/FakeObjectUnitTest.java:

// Package and imports omitted

public class FakeObjectUnitTest {
    @Test
    public void doSomething() {
        int x = 5;

        Assert.assertEquals(x, 5);
    }
}

我的build.xml:

<project name="" basedir="..">
    <!-- Main classpath. -->
    <path id="main.class.path">
        <fileset dir="bin/main"/>
    </path>

    <!-- Test classpath. -->
    <path id="test.class.path">
        <fileset dir="bin/test"/>
    </path>

    <!-- JUnit classpath. -->
    <path id="junit.class.path">
        <fileset dir="lib/main" includes="*.jar"/>
        <fileset dir="lib/test" includes="*.jar"/>
        <path refid="main.class.path"/>
        <path refid="test.class.path"/>
    </path>

    <!--
        All previous targets omitted for brevity (such as for compiling, etc.), but
    I assure you all that they work and compile FakeObject.java/FakeObjectUnitTest.java into
    FakeObject.class/FakeObjectUnitTest.class respectively, and place them in the correct
bin directories.
    -->

    <target name="run-junit" depends="compile">

        <property name="junit.path" refid="junit.class.path"/>
        <echo message="JUnit ClassPath is: ${junit.path}"/>

        <junit printsummary="yes" haltonerror="yes" haltonfailure="yes">
            <classpath refid="junit.class.path"/>

            <formatter type="xml"/>

            <batchtest todir="gen/reports">
                <fileset dir="src/test/java">
                    <include name="**/*UnitTest*.java"/>
                </fileset>
            </batchtest>
        </junit>
    </target>
</project>

当我从命令行运行此目标时:

run-junit:
    [echo] Conducting unit tests with JUnit.
    [echo] JUnit ClassPath is: /<path-to-my-project>/MyProject/lib/test/hamcrest-1.1.jar:/<path-to-my-project>/MyProject/lib/test/junit-4.10.jar:/<path-to-my-project>/MyProject/bin/main/com/myproject/client/FakeObject.class:/<path-to-my-project>/MyProject/bin/test/com/myproject/client/FakeObjectUnitTest.class
    [junit] Running com.myproject.client.FakeObjectUnitTest
    [junit] Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 0 sec

我这样做是为了证明它FakeObjectUnitTest.class在JUnit类路径上看到了.但是,它失败并出现错误.当我进入此测试的XML TEST报告时,我看到以下内容:

<error message="com.myproject.client.FakeObjectUnitTest" type="java.lang.ClassNotFoundException">java.lang.ClassNotFoundException: com.myproject.client.FakeObjectUnitTest
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
    at java.lang.Class.forName0(Native Method)
    at java.lang.Class.forName(Class.java:247)
</error>

当我以详细模式(-v)运行Ant时,我看到的唯一提示是一堆警告:

忽略异常java.util.zip.ZipException:打开zip文件读取资源x时出错

... x类文件的名称在哪里.

我在SO上发现了这个问题,结果问题是作者已经将类文件添加到类路径中,而不是JAR(这使得JUnit不满意).所以我尝试删除main.class.path和test.class.path从junit.class/path然后我得到一个异常,没有找到任何类文件.

关于发生了什么的任何想法或想法？在此先感谢,对不起这个-v问题,但我认为更多细节越多越好.

Answer 1

您需要使用类似包的结构:
从手册:

只要需要指定类似路径的值,就可以使用嵌套元素.这采取以下一般形式:

    <classpath>
      <pathelement path="${classpath}"/>
      <pathelement location="lib/helper.jar"/>
    </classpath>

所以你的解决方案看起来像:

<!-- JUnit classpath. -->
<path id="junit.class.path">
    <fileset dir="lib/main" includes="*.jar"/>
    <fileset dir="lib/test" includes="*.jar"/>
    <pathelement location="bin/main"/>
    <pathelement location="bin/test"/>
</path>
