Question

之前只使用过SBT和Maven，我无法让Ant与Junit测试一起工作。我已经看过无数其他与此相关的类似问题但是无法解决。从Eclipse内部运行时，这些测试运行良好。失败的测试类抛出“NoClassDefFoundError”

My Ant build.xml片段：

    <project name="APPbuild" basedir=".">

    <description>APP build</description>

    <property name="webinf" location="WEB-INF" />
    <property name="src" location="${webinf}${file.separator}src" />
    <property name="src.test" location="${webinf}${file.separator}test" />
    <property name="classes" location="${webinf}${file.separator}classes" />
    <property name="classes.test" location="${webinf}${file.separator}classestest" />
    <property name="classes.instrument" location="${webinf}${file.separator}classesinstrument" />
    <property name="dist" location="..${file.separator}dist" />
    <property name="archiveFile" location="${dist}${file.separator}app.war" />
    <property name="classpath" location="${webinf}${file.separator}lib" />
    <property name="classpath.test" location="${webinf}${file.separator}resources${file.separator}test" />
<property name="junit.output.dir" value="${webinf}${file.separator}junit" />
<path id="libpath">
        <fileset dir="${classpath}">
            <include name="**${file.separator}*.jar" />
        </fileset>
    </path>

    <path id="libpath_test">
        <fileset dir="${classpath}">
            <include name="**${file.separator}*.jar" />
        </fileset>
        <fileset dir="${classpath.test}">
            <include name="**${file.separator}*.jar" />
        </fileset>
    </path>

    <path id="test.classpath">
        <pathelement location="${src}" />
        <pathelement location="${src.test}" />
        <pathelement location="${classes}" />
        <pathelement location="${classpath}" />
        <pathelement location="${classpath.test}" />
        <pathelement location="${webinf}${file.separator}resources${file.separator}test${file.separator}junit-4.7.jar" />
    </path>
<target name="compile" depends="init,prepare">
        <javac classpathref="libpath" debug="on" srcdir="${src}" destdir="${classes}" includeantruntime="false" />
    </target>

    <target name="compile_test" depends="compile">
        <javac classpathref="libpath_test" srcdir="${src.test}" destdir="${classes}" includeantruntime="false" />
    </target>

<target name="test" depends="compile_test">
        <mkdir dir="${junit.output.dir}" />
        <junit fork="true" printsummary="true" showoutput="true">
            <formatter type="xml" />
            <classpath refid= "test.classpath" />
            <batchtest todir="${junit.output.dir}">
                <fileset dir="${classes}">
                    <include name="**/*Test.class" />
                </fileset>
            </batchtest>
        </junit>
        <echo>${classpath}</echo>
        <echo>${classpath.test}</echo>
        <echo>${classes}</echo>
        <echo>${classes.test}</echo>
    </target>

其中一个测试类

出错

java.lang.NoClassDefFoundError: javax/mail/Address
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Unknown Source)
Caused by: java.lang.ClassNotFoundException: javax.mail.Address
at java.net.URLClassLoader$1.run(Unknown Source)
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)

另一个

java.lang.NoClassDefFoundError: org/dbunit/database/IDatabaseConnection
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Unknown Source)
Caused by: java.lang.ClassNotFoundException: org.dbunit.database.IDatabaseConnection

at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)

此时的任何指针或提示都会很棒。

Answer 1

汉克关于这个问题/位置的提示使我发现以下情况有效。

将test.classpatch id更改为以下内容现在可以获取所有必需的应用程序并测试lib。

<path id="test.classpath">
    <pathelement location="${classes}" />
    <fileset dir="${classpath}" includes="**/*.jar"/>
    <fileset dir="${classpath.test}" includes="**/*.jar"/>
</path>

非常感谢汉克！

Ant在执行正在运行的Junit Target时抛出NoClassDefFoundError，在Eclipse中运行正常
