Question

我只是想从命令行运行一个简单的JUnit测试

mvn clean test -Dtest=src/test/java/scraper/ScrapeTest#dbConnectionTest

导致这种情况（为简洁起见）

[ERROR] COMPILATION ERROR :
[ERROR] /mnt/c/Users/My Name/Workspace/MyProject/MyProject/src/test/java/scraper/ScrapeTest.java:[3,24] package org.junit does not exist
[ERROR] /mnt/c/Users/My Name/Workspace/MyProject/MyProject/src/test/java/scraper/ScrapeTest.java:[20,10] cannot find symbol
  symbol:   class Test
  location: class scraper.ScrapeTest

我不明白，因为依赖项肯定包含在pom.xml文件中。我删除了所有标记，并按照其他类似问题中的建议设置了源和目标，并且还将sourceEncoding设置为UTF-8，因为我对此有所警告，并认为可能不是'@'符号正确识别，但说实话，我不知道出了什么问题；只是将{{poop emoji}}扔在墙上，看看有什么木棍。

这是我要运行的测试。

package scraper;

import static org.junit.Assert.*;

import java.io.IOException;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

import org.junit.Test;

public class ScrapeTest {

    //TODO fix connection issues
    private final String connectionUrl = "nunyabizniz";

    @Test
    public void dbConnectionTest() {
        try {
            //Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver.class");
            Connection connection = DriverManager.getConnection(connectionUrl);
            assert(true);
        }
        // Handle any errors that may have occurred.
        catch (Exception e) {
            System.out.println(e.getMessage());
            assert(false);
        }
    }
}

您最终需要通过范围测试将junit依赖项添加到pom文件中，

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.12</version>
  <scope>test</scope>
</dependency>

Maven编译错误：包org.junit不存在
