1 安装环境

1.1 安装VSCode

下载

1.2 安装Chocolate

以管理员身份运行Powershell, 执行以下命令安装Chocolate：

Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

1.3 安装AdoptOpenJDK

• 打开官网手动下载，手动下载的目的是解决Coding Pack for Java 下载过慢
• 选择OpenJDK11 和 HotSpot
• 下载并安装
• 

1.4 安装maven

管理员权限运行CMD 或者 PowerShell ，执行

choco install maven -y

1.5 安装Coding Pack for Java

• 下载Coding Pack for Java
• 点击Next
  
• 点击Install
  
• 安装完成
  
• 此时Java Extension Pack已经安装好

2 Maven工程

2.1 添加settings.json配置

添加.vscode目录,并添加settings.json文件

在文件中添加以下内容

    "[json]": {
        "editor.defaultFormatter": "vscode.json-language-features"
    },
    "[java]": {

2.1 从模板创建Maven工程

按如下顺序点击

• 创建Java工程
  
• 从archetype创建Maven
  
• 选择maven-archetype-quickstart
  
• 选1.4
  
• 选择一个目录，比如这里选择java
• 等待一堆下载后 出现如下
  
• 如果网络不佳，会一直卡在Generating project in Interactive mode
  可以选择添加参数-DarchetypeCatalog=internal 手动执行

mvn org.apache.maven.plugins:maven-archetype-plugin:3.1.2:generate -DarchetypeArtifactId="maven-archetype-quickstart" -DarchetypeGroupId="org.apache.maven.archetypes" -DarchetypeVersion="1.4" -DarchetypeCatalog=internal

• 运行成功

2.2 清除language server

如果代码中出现了以下错误提示

The declared package "com.aura" does not match the expected package "app" Java(536871240)

则是Language Server的缓存目录不干净
按照以下操作进行处理:

• 按F1 打开命令框
• 选择Java: Clean the Java language server workspace
• 点击 Restart and delete

2.3 调试/启动

• 打开App.java, 点击F5 启动调试
• 此时会弹出提示，不要安装Dependency Analytic，这个依赖检查太严格会对log4j等依赖报红色波浪线，选择Never永远不装。
  
• 另一个提示是安装vscode-xml，这个插件比较好用，建议安装。
• 等待一会，出现Hello World 运行成功

2.4 生成可直接运行的Jar包

• 打开pom.xml 添加以下配置

<build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>2.4.1</version>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>shade</goal>
            </goals>
            <configuration>
              <transformers>
                <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                  <mainClass>com.aura.App</mainClass>
                </transformer>
                <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                  <resource>META-INF/spring.handlers</resource>
                </transformer>
                <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                  <resource>META-INF/spring.schemas</resource>
                </transformer>
              </transformers>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
</build>

• 右键点击 maven project test
  

• 点击package
  

• 构建成功
  

• 运行
