Question

我在Eclipse中创建了一个非常简单的项目来运行一个非常简单的JUnit测试。从Eclipse中执行测试时，这些测试工作正常，但是当通过maven命令行运行时，代码无法编译。

我用来运行maven的命令只是'maven test'。以下是maven输出：

MacBook-Pro:leonard-reference-test randy$ mvn test

这个的pom.xml如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </plugin>
        </plugins>
    </build>

</project>

项目中唯一的Java文件如下：

package info.leonard.reference.test;

import org.junit.Test;

public class ReferenceTestClient
{
    @Test
    public void testOne()
    {
        System.out.println("simple test");
    }
}

就是这样......项目中没有其他文件。 Maven测试在Eclipse中成功运行，但代码甚至不能在Maven中编译。

对此简单项目的有效pom.xml文件或其他修改表示赞赏。

Answer 1

您的文件位于src/main/java/目录中，但JUnit依赖项的范围是test。这意味着maven在编译非测试代码时不会考虑它。请将您的文件放在src/test/java。

Answer 2

测试范围意味着junit仅在src / test / java

中可用
