本篇概览

  • 本文是《quarkus 实战》系列的第五篇，一起去相熟 quarkus 的 maven 插件（就是下图红框中的那个 plugin），用好它能够使咱们更加得心应手的在我的项目中配置和管制 quarkus
  • 插件 <font color=”blue”>quarkus-maven-plugin</font> 提供了丰盛的性能，它们都有对应的命令，执行 <font color=”red”>mvn quarkus:xxx</font> 即可执行，其中 xxx 就是具体的命令，例如 <font color=”blue”>mvn quarkus:help</font>，接下来一起用实际操作来相熟这些命令

帮忙（help）

  • <font color=”blue”>mvn quarkus:help</font> 是首先要把握的命令，它通知了大家 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，仅列出局部内容：
% 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.
...

创立工程（create）

  • 首先要把握的 mvn 命令是创立工程，回顾前文中创立工程的命令：
mvn "io.quarkus:quarkus-maven-plugin:create" \
  -DprojectGroupId="com.bolingcavalry" \
  -DprojectArtifactId="hello-quarkus" \
  -DprojectVersion="1.0-SNAPSHOT" \
  -DclassName="HobbyResource" \
  -Dpath="actions"
  • 创立工程时有很多参数能够设置，它们的默认值的作用如下表
参数 默认值 阐明
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，会主动创立一个类
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，列表只能依据 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 <font color=”blue”>mvn quarkus:info</font>，应用频率很高，如下，能够察看以后的 BOM 和扩大插件状况：
(base) willdeMBP:hello-quarkus will$ mvn quarkus:info

paltform 列表（list-platforms）

  • 回顾我的项目的 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对立治理
  • 上图红框中的平台，在 quarkus 中有多个，咱们能够依照本人的理论状况抉择，quarkus 插件的 list-platforms 命令能够查看一共有哪些平台类型，残缺命令是
mvn quarkus:list-platforms
  • 控制台输入所有平台信息

扩大组件：查看（list-extensions）

  • 扩大组件 (extensions) 是 quarkus 的一大特色，web、序列化、数据库等丰盛的性能，都有对应的组件提供
  • 命令 <font color=”blue”>mvn quarkus:list-extensions</font> 能够查看反对的扩大组件列表：

  • 如果想看更丰盛的信息，能够减少参数 <font color=”blue”>-Dformat=full</font>，如下图红框所示，新增了两个字段：

扩大组件：查看分类（list-categories）

  • 间接用 list-extensions 命令能够看到所有扩大组件，咱们当然不会全副都用，所以最好能有个分类的性能，而后咱们在适合的类目中找寻本人须要的组件
  • quarkus 曾经为咱们筹备好了分类性能，首先，执行以下命令查看有哪些分类（-Dformat 参数可选，有了它会展现更具体的信息）
mvn quarkus:list-categories -Dformat=full
  • 控制台输入如下，列出了所有分类和阐明
% mvn quarkus:list-categories -Dformat=full

查看依赖树（dependency-tree）

  • 咱们罕用 <font color=”blue”>mvn dependency:tree</font> 命令查看 maven 工程的依赖树，此命令是依据 pom.xml 的依赖信息剖析出所有间接和间接依赖关系，然而，在 quarkus 利用中存在一些非凡状况：quarkus 的 maven 插件参加了构建，它会依据以后的 quarkus 扩大组件（extensions）去增加对应的依赖，这是 maven 自身不晓得的，因而，举荐应用 <font color=”blue”>mvn quarkus:dependency-tree</font> 命令查看 quarkus 利用的依赖关系：

离线构建（go-offline）

  • 先回顾一个 maven 命令 <font color=”blue”>mvn dependency:go-offline</font>，其作用是事后下载所有依赖库到本地，这样构建的时候就算没有网络，也能胜利构建
  • 然而对于 quarkus 利用，因为 quarkus 扩大组件（extensions）不能被 maven 辨认和解决，因而无奈剖析出这些 quarkus 扩大组件的依赖库，导致 <font color=”blue”>mvn dependency:go-offline</font> 命令无奈下载这些依赖库
  • 为了解决上述问题，倡议应用 <font color=”blue”>mvn quarkus:go-offline</font> 命令，此命令会剖析扩大组件的依赖项，而后下载缓存到本地
