Debug Vert.x app using Gradle and VS Code

问题

我正在使用一个使用 Java 编写 Vert.x 应用程序，其中包含一些顶点（verticles）。该应用程序使用一个 MainVerticle 进行启动，并使用 Gradle 进行构建。我使用 VS Code 作为集成开发环境（IDE）/代码编辑器，因为它非常简单且轻量。然而，我发现很难找到一种调试代码的方法。请问如何配置 build.gradle 和 .vscode/launch.json 以启用调试选项？

到目前为止，这是我在 build.gradle 文件中用于启动的命令：

  1. run {
  2.   args = [ 'run', mainVerticleName, "--redeploy=$watchForChange", "--launcher-class=$mainClassName", "--on-redeploy=$doOnChange" ]
  3. }
英文:

I'm working with a Vert.x app with verticles written in Java. The app uses a MainVerticle to start and uses Gradle for its construction. I'm using VS Code as IDE/Code Editor since it is really simple and lightweight. However it has been really difficult to find a way to debug my code. How do I configure build.gradle and .vscode/launch.json to enable debug options?

So far this is my command to start in build.gradle file:

  1. run {
  2.   args = [ 'run', mainVerticleName, "--redeploy=$watchForChange", "--launcher-class=$mainClassName", "--on-redeploy=$doOnChange" ]
  3. }

我正在为Java开发者使用VS Code，并且我的微服务使用Eclipse Vertx.io。这在Maven中很容易配置。使用Maven创建Vertx项目并修改它以满足自己的使用需求。

我已经对它进行了修改，并获得了类似的项目（不完全相同，不能展示完整的代码）：

  1. package com.test.service;
  3. import io.vertx.config.ConfigRetriever;
  4. import io.vertx.core.AbstractVerticle;
  5. import io.vertx.core.DeploymentOptions;
  6. import io.vertx.core.Promise;
  8. public class Application extends AbstractVerticle {
  10.   @Override
  11.   public void start(Promise<Void> startPromise) throws Exception {
  12.     ConfigRetriever retriever = ConfigRetriever.create(vertx);
  13.     retriever.getConfig(
  14.         res -> {
  15.           try {
  16.             if (res.failed()) {
  17.               // ...
  18.             } else {
  19.               startPromise.complete();
  20.               vertx.deployVerticle(
  21.                   new TestServiceVerticle(),
  22.                   new DeploymentOptions().setConfig(res.result()));              
  23.             }
  24.           } catch (RuntimeException e) {
  25.             // ...
  26.             startPromise.fail(e.getMessage());
  27.           }
  28.         });
  29.   }
  30. }

Pom.xml：

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  3.   <modelVersion>4.0.0</modelVersion>
  5.   <groupId>test</groupId>
  6.   <artifactId>test</artifactId>
  7.   <version>1.0.0-SNAPSHOT</version>
  9.   <!-- ... 省略其他部分 ... -->
  11. </project>

调试设置：

  1. {
  2.   "type": "java",
  3.   "name": "Run service",
  4.   "request": "launch",
  5.   "mainClass": "io.vertx.core.Launcher",
  6.   "args": "run test.test.service.Application"
  7. }

希望这对您有所帮助。

I'm woking on VS Code for Java devs and my microservices uses Eclipse Vertx.io. It's is easy to configure for maven. Use maven create vertx project and modify it own usage.

I have modified it and got similar project (not eaxact cannot show full code)

package com.test.service;

  1. import io.vertx.config.ConfigRetriever;
  2. import io.vertx.core.AbstractVerticle;
  3. import io.vertx.core.DeploymentOptions;
  4. import io.vertx.core.Promise;
  6. public class Application extends AbstractVerticle {
  8.   @Override
  9.   public void start(Promise&lt;Void&gt; startPromise) throws Exception {
  10.     ConfigRetriever retriever = ConfigRetriever.create(vertx);
  11.     retriever.getConfig(
  12.         res -&gt; {
  13.           try {
  14.             if (res.failed()) {
  15.               .....
  16.             } else {
  17.               startPromise.complete();
  18.               vertx.deployVerticle(
  19.                   new TestServiceVerticle(),
  20.                   new DeploymentOptions().setConfig(res.result()));              
  21.             }
  22.           } catch (RuntimeException e) {
  23.             ...
  24.             startPromise.fail(e.getMessage());
  25.           }
  26.         });
  27.   }
  28. }
