Question

我在尝试从POM.xml安装Maven依赖项时遇到编译错误。

我尝试添加和删除许多依赖项，但是我不确定为什么错误会出现在我的项目中。我将同样添加我的POM.xml文件。您能告诉我这些依赖项有什么问题吗？

我要为相同的内容添加输出：-

Answer 1

首先。您没有安装适当的依赖项

<!-- https://mvnrepository.com/artifact/org.assertj/assertj-core -->
<dependency>
    <groupId>org.assertj</groupId>
    <artifactId>assertj-core</artifactId>
    <version>3.13.2</version>
    <scope>test</scope>
</dependency>

第二。在处理依赖项时，请注意适当的范围。这可能会在不同情况下影响库的设置。

软件包org.assertj.core.api不存在
