Eclipse IDE版本2019-09 R（4.13.0）无法识别Maven依赖项

Question

我的Eclipse版本

Eclipse IDE for Enterprise Java Developers.
Version: 2019-09 R (4.13.0)
Build id: 20190917-1200
OS: Windows 10, v.10.0, x86_64 / win32
Java version: 13.0.1

我创建一个具有pom.xml

的Java应用程序

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <dependencies>
        <dependency>
            <groupId>org.junit.jupiter</groupId>

            <scope>test</scope>
        </dependency>
        <dependency>

            <scope>test</scope>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.8.1</version>
                <configuration>
                    <source>8</source>
                    <target>8</target>
                </configuration>
            </plugin>

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-eclipse-plugin</artifactId>
                <version>2.10</version>
            </plugin>            
        </plugins>
    </build>
</project>

样品分类

package com.sample.junit5;

import static org.junit.jupiter.api.Assertions.fail;

public class StringTest {

    @Test
    void test() {
        fail("Not yet implemented");
    }

}

但是Eclipse IDE版本2019-09 R（4.13.0）无法识别Maven依赖项

如何解决？

Answer 1

Junit依赖项在pom.xml的测试范围中声明（如预期的那样），因此您的测试类必须位于test文件夹中：src / test / java而不是src / main / java。
