无法运行用于构建 ant 项目的脚本答案

【问题标题】：Cannot run script for building ant projects无法运行用于构建 ant 项目的脚本
【发布时间】：2020-02-11 03:51:25
【问题描述】：

我正在尝试编写一个脚本，该脚本将通过 ant project builder 构建一个项目。

测试运行没有问题。用户类也很好。但是当我运行 build.xml 时，我得到了这些错误。

我将在此处添加该类的 User-class 和 UserTest。

谁能解释这段代码有什么问题？

用户类

package ua.nure.kn.susidskyi.usermanagement;

import java.util.Date;
import java.io.Serializable;
import java.util.Calendar;

public class User implements Serializable{
    private static final long serialVersionUID = -112812758632339479L;

UserTest 用于用户类

package ua.nure.kn.susidskyi.usermanagement;

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;

import junit.framework.TestCase;

public class UserTest extends TestCase {

    private User user;
    @BeforeEach
    protected void setUp() throws Exception {
        super.setUp();
        user = new User(1L, "Александр", "Соседский", new SimpleDateFormat("d-MM-yyyy").parse("11-09-2000"));
    }

    public void testGetFullName() {
        assertEquals("Соседский Александр", user.getFullName());
    }

    public void testGetAge() {
        assertEquals(19, user.getAge());
    }

    public void testGetAgeBirthdayToday() {
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(new Date());
        user.setDateOfBirth(calendar.getTime());
        assertEquals(0, user.getAge());
    }

    public void testGetAgeBirthdayLater() {
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(new Date());
        calendar.add(Calendar.YEAR, 1);
        user.setDateOfBirth(calendar.getTime());
        assertEquals(-1, user.getAge());
    }

    public void testGetAgeThisMonthEarlier() {
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(new Date());
        calendar.add(Calendar.DATE, -2);
        user.setDateOfBirth(calendar.getTime());
        assertEquals(0, user.getAge());
    }

    public void testGetAgeDayThisMonthLater() {
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(new Date());
        calendar.add(Calendar.DATE, 2);
        user.setDateOfBirth(calendar.getTime());
        assertEquals(0, user.getAge());
    }
}

【问题讨论】：

您的javac 任务必须指定类路径以搜索所有这些导入。

标签： java eclipse ant

【解决方案1】：

您正在尝试使用 JUnit Jupiter API 中的类，但您只在类路径中包含了普通的 JUnit jar。

你可以在这里找到你需要的罐子：https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-api

然后你可以将它包含在你的测试编译中：

<target name="test-compile" depends="compile">
  <javac srcdir="${test-java-dir}" destdir="${build-dir}">
    <classpath>
      <path location="${lib-dir}/junit.jar" />
      <path location="${lib-dir}/junit-jupiter-api.jar" />
    </classpath>
  </javac>
</target>
