Java NoClassDefFoundError通过Ant运行测试但在Tomcat中部署时工作

当我通过ant运行时，我得到NoClassDefFoundError，但当我在tomcat中部署应用程序时，它正在工作

<path id="classpath.test">
    <pathelement location="WebContent/WEB-INF/lib/junit-4.11.jar"/>
    <pathelement location="WebContent/WEB-INF/lib/hamcrest-all-1.3.jar"/>

    <pathelement location="${main.build.dir}"/>
</path>

    </javac>
</target>

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

我使用

ant test

我猜DBCP当前打包在${CATALINA_HOME}/lib中，即Tomcat的lib目录中。由

FooTest

运行的代码中定义的数据源必须定义为

BasicDataSource

，因此您应该在

classpath.test

中为

commons dbcp.jar
