quarkus实战之五：细说maven插件

2023-07-25 08:02 由 程序员欣宸 发表于 #后端开发
  • quarkus的maven插件非常重要，管理和构建工程时都离不开，本篇就来一起了解和掌握它

欢迎访问我的GitHub

这里分类和汇总了欣宸的全部原创(含配套源码)：https://github.com/zq2599/blog_demos

本篇概览

  • 本文是《quarkus实战》系列的第五篇，一起去熟悉quarkus的maven插件（就是下图红框中的那个plugin），用好它可以使我们更加得心应手的在项目中配置和控制quarkus

  • 插件quarkus-maven-plugin提供了丰富的功能，它们都有对应的命令，执行mvn quarkus:xxx即可执行，其中xxx就是具体的命令，例如mvn quarkus:help，接下来一起用实际操作来熟悉这些命令

帮助（help）

  • mvn quarkus:help是首先要掌握的命令，它告诉了大家quarkus的maven插件到底有哪些能力，作为工具书，今后随时可能用到，如下所示，篇幅所限，仅列出部分内容：
% mvn quarkus:help

[INFO] Quarkus Platform - Quarkus Maven Plugin 2.7.3.Final
  Quarkus Universe platform aggregates extensions from Quarkus Core and those
  developed by the community into a single compatible and versioned set that
  application developers can reference from their applications to align the
  dependency versions

This plugin has 25 goals:

quarkus:add-extension
  Allow adding an extension to an existing pom.xml file. Because you can add one
  or several extension in one go, there are 2 mojos: add-extensions and
  add-extension. Both supports the extension and extensions parameters.

quarkus:add-extensions
  Allow adding extensions to an existing pom.xml file. Because you can add one
  or several extension in one go, there are 2 mojos: add-extensions and
  add-extension. Both supports the extension and extensions parameters.

quarkus:analyze-call-tree
  Analyze call tree of a method or a class based on an existing report produced
  by Substrate when using -H:+PrintAnalysisCallTree, and does a more meaningful
  analysis of what is causing a type to be retained.

quarkus:build
  Builds the Quarkus application.
...

创建工程（create）

  • 首先要掌握的mvn命令是创建工程，回顾前文中创建工程的命令：
mvn "io.quarkus:quarkus-maven-plugin:create" \
  -DprojectGroupId="com.bolingcavalry" \
  -DprojectArtifactId="hello-quarkus" \
  -DprojectVersion="1.0-SNAPSHOT" \
  -DclassName="HobbyResource" \
  -Dpath="actions"
  • 创建工程时有很多参数可以设置，它们的默认值的作用如下表
参数 默认值 说明
projectGroupId org.acme.sample group id，GAV坐标中的G
projectArtifactId mandatory artifact id， GAV坐标中的A
projectVersion 1.0.0-SNAPSHOT version， GAV坐标中的V
platformGroupId io.quarkus.platform 在依赖quarkus的BOM，以及quarkus插件时，都要指定GAV，这是G
platformArtifactId quarkus-bom 在依赖quarkus的BOM，以及quarkus插件时，都要指定GAV，这是A
platformVersion 2.7.1.Final 在依赖quarkus的BOM，以及quarkus插件时，都要指定GAV，这是V，默认值会自动更新到最新稳定版
className 无默认值 指定后，会自动创建一个类
path 无默认值 如果指定了className，此时再指定path的话，path会作为类的web接口的path
extensions 空 所需的quarkus插件列表
quarkusRegistryClient true 是否联网获取最新的quarkus插件列表，如果设置为false，列表只能根据BOM获取，得不到最新的在线数据

查看工程信息（info）

  • 查看工程信息的命令是mvn quarkus:info，使用频率很高，如下，可以观察当前的BOM和扩展插件情况：
(base) willdeMBP:hello-quarkus will$ mvn quarkus:info
[INFO] Scanning for projects...

paltform列表（list-platforms）

  • 回顾项目的pom.xml文件，如下图，红框中是依赖的平台信息，所有quarkus依赖库都由这个平台统一管理

  • 上图红框中的平台，在quarkus中有多个，我们可以按照自己的实际情况选择，quarkus插件的list-platforms命令可以查看一共有哪些平台类型，完整命令是
mvn quarkus:list-platforms
  • 控制台输出所有平台信息
% mvn quarkus:list-platforms

扩展组件：查看（list-extensions）

  • 扩展组件(extensions)是quarkus的一大特色，web、序列化、数据库等丰富的功能，都有对应的组件提供
  • 命令mvn quarkus:list-extensions可以查看支持的扩展组件列表：
(base) willdeMBP:hello-quarkus will$ mvn quarkus:list-extensions

  • 如果想看更丰富的信息，可以增加参数-Dformat=full，如下图红框所示，新增了两个字段：

扩展组件：查看分类（list-categories）

  • 直接用list-extensions命令可以看到所有扩展组件，我们当然不会全部都用，所以最好能有个分类的功能，然后我们在合适的类目中找寻自己需要的组件
  • quarkus已经为我们准备好了分类功能，首先，执行以下命令查看有哪些分类（-Dformat参数可选，有了它会展示更详细的信息）
mvn quarkus:list-categories -Dformat=full
  • 控制台输出如下，列出了所有分类和说明

查看依赖树（dependency-tree）

  • 我们常用mvn dependency:tree命令查看maven工程的依赖树，此命令是根据pom.xml的依赖信息分析出所有直接和间接依赖关系，然而，在quarkus应用中存在一些特殊情况：quarkus的maven插件参与了构建，它会根据当前的quarkus扩展组件（extensions）去添加对应的依赖，这是maven本身不知道的，因此，推荐使用mvn quarkus:dependency-tree命令查看quarkus应用的依赖关系：
(base) willdeMBP:hello-quarkus will$ mvn quarkus:dependency-tree
[INFO] Scanning for projects...
[INFO] 
[INFO] ------------------< com.bolingcavalry:hello-quarkus >-------------------

...

离线构建（go-offline）

  • 先回顾一个maven命令mvn dependency:go-offline，其作用是预先下载所有依赖库到本地，这样构建的时候就算没有网络，也能成功构建
  • 但是对于quarkus应用，因为quarkus扩展组件（extensions）不能被maven识别和处理，因此无法分析出这些quarkus扩展组件的依赖库，导致mvn dependency:go-offline命令无法下载这些依赖库
  • 为了解决上述问题，建议使用mvn quarkus:go-offline命令，此命令会分析扩展组件的依赖项，然后下载缓存到本地
