识别 Maven 中的依赖项

Posted 2023-03-30

技术标签:

【中文标题】识别 Maven 中的依赖项【英文标题】：Identifying Dependencies in Maven 【发布时间】：2021-03-27 04:39:20 【问题描述】：

我们有一个使用 maven 构建的 Spring Boot 项目。现在我必须确定哪些依赖项很重要，哪些不应该构建到 jar 文件中，哪些不应该。我找到了一个命令“mvn dependency:analyze”，它显示了未使用和已使用的依赖项。

例如，在未使用的依赖项下，我可以看到 lombok 被列出，未使用的依赖项应该被删除我阅读，但如果我删除它，我无法执行 mvn clean install，因为我们的项目中使用了 lombok。

我的问题是如何以安全的方式清理 pom？并从 jar 中排除依赖项。我是 Maven 新手。

这是使用未声明的依赖项：

【问题讨论】：

你能发布mvn dependency:tree 和mvn dependency:analyze 的输出吗？即使是 sn-ps 或编辑 com.hasan.employer 条目也有助于提供答案。嗨，我发布了你想要的结果最重要的部分是不存在 pom.xml 文件......并且在 spring boot 中说不需要的东西是一种有趣的方法吗？你知道它什么时候用过吗？这是我的问题的一部分，我如何验证是否使用了某些东西？例如，我们的项目中使用了 lombok，但命令说它未使用... 【参考方案1】：

您应该了解 Maven 的依赖范围： https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#dependency-scope

例如，对于 Lombok，应使用 provided 范围，详细说明 here。

【讨论】：

我会看看这个。谢谢。一个问题是我应该决定排除或不排除依赖项的标准是什么？没有酸性测试。什么意思？我的意思是你只需要知道。例如，我看到您将 H2 作为依赖项。您正在使用它进行单元测试，对吗？那么范围应该是test，因为您的应用在运行时不需要它。我真的无法比 apache 手册更好地解释它。但是，除非您遇到问题，否则我认为您不应该排除任何东西。

以上是关于识别 Maven 中的依赖项的主要内容，如果未能解决你的问题，请参考以下文章

可以使Maven构建包含依赖项中的.class文件[重复]

为啥即使我的 maven 依赖项中有第三方依赖项，也只需要 OSGi 容器中的第三方依赖项？

Eclipse 中的项目无法解析 Maven 依赖项中存在的 jars

在 Maven 依赖项中定位资源的 URI 方案？

mvn 命令用于更新依赖项中的版本和一个使用该依赖项的项目

依赖项中的 JUnit 版本错误
