本文介紹了使用vert.x maven插件快速創建項目的方法，分享給大家，具體如下：
文檔地址： https://reactiverse.io/vertx-maven-plugin
已有項目添加該插件
在項目 pom.xml 目錄，執行下面的命令即可添加：
|
1
|
mvn io.reactiverse:vertx-maven-plugin:1.0.17:setup |
執行該命令后，在 pom.xml 中會增加下面的配置：

自動引入的 vert.x 版本為 3.5.3，你可以通過在 mvn 命令增加 -dvertxversion=3.4.0 這個參數來指定需要的版本。
從頭創建空項目
首先你 必須創建一個目錄 ，vert.x 插件不會自動給你創建目錄，只會創建目錄內的 src 和 pom.xml 等文件。
創建一個目錄，進入該目錄內，在該目錄內執行下面的命令：
|
1

3
4

7
|
mvn io.reactiverse:vertx-maven-plugin:1.0.17:setup ^ -dprojectgroupid=org.acme ^ -dprojectartifactid=acme-project ^ -dprojectversion=1.0-snapshot ^ -dverticle=org.acme.foo ^ -dverticle=io.vertx.sample.myfirstverticle ^ -ddependencies=web |
如果你使用的 linux 系統，將上面的 ^ 改為 \ 。
這里和上面相比增加了項目 gav 的配置。
通過 -dverticle=io.vertx.sample.myfirstverticle ，可以生成一個默認的 verticle 類。
通過 -ddependencies=web 可以指定你想加入的 vert.x 的依賴，這里寫的名字都是縮寫，具體對應關系看下面的介紹。
使用上面命令后，就創建了一個基礎 vert.x 項目，在開始學習 vert.x 的時候，通過這種方式可以更快的創建基礎項目。
-ddependencies 對照表
下面 json 中的 labels 就是縮寫名，groupid 和 artifactid 是對應的依賴。

打包項目
集成了 vert.x 插件后，打包變的極其容易，只需要下面的命令：
|
1
|
mvn clean package |
通過這種方式就會打出一個 fat jar 包，可以直接通過 java -jar xxxx.jar 運行的包。
其他命令
除了上面這些，還有 vertx:run, vertx:debug, vertx:start, vertx:stop 命令，這些命令可以在不打 jar 包的情況下運行或者關閉項目。
常見問題
通過插件方式運行時，你經常會遇到下面的問題：
[info] 嚴重: java.net.bindexception: address already in use: bind
這種情況是因為使用類似 idea maven 插件中的命令直接雙擊運行時，你無法關閉這個應用。如果你使用的純命令行，直接 ctrl+c 就能關閉。
使用 vertx:run 在命令行運行時可以直接關閉。
使用 vertx:start 運行時，需要通過 vertx:stop 關閉。
萬一遇上無法關閉的情況，在 windows 中，可以用下面方式解決。
在命令行中，輸入下面的命令：
|
1
|
jps -m |
這個命令會列出所有運行的 jvm：
15248 jps -m
2384 launcher run io.vertx.sample.myfirstverticle redeploy-termination-period=1000 -dvertx.id=5fd656fa-55a9-46b4-8d23-caa95f2e5032-redeploy
8208
11844 launcher run io.vertx.sample.myfirstverticle redeploy-termination-period=1000 -dvertx.id=bec46d01-d441-4949-a2d9-f8ffbe85f965-redeploy
14200 launcher run io.vertx.sample.myfirstverticle --redeploy=f:\git\my-first-vertx-app\target\classes/**/* --redeploy-scan-period=1000 redeploy-termi
nation-period=1000 --launcher-class=io.vertx.core.launcher
7580 launcher clean compile vertx:run
根據后面的信息找到你想關閉的 jvm。輸入下面的命令(假設關閉 2384）：
|
1
|
taskkill /f /pid 2384 |
當相同端口的 jvm 關閉后，你就可以再次運行了。
