1. 初始化项目

1. 新建一个Idea 插件项目,当前选择的是gradle的 项目

2. 修改gradle内的相关依赖仓库的镜像为国内仓库

   image-20211221194353541
   • settings.gradle

   pluginManagement {
       repositories {
           maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
           gradlePluginPortal()
       }
   }
   rootProject.name = 'ideaPluginTest'

• build.gradle 添加仓库镜像并设置当前项目为UTF8格式

     plugins {

     }

     group 'org.intellij.sdk'
     version '2.0.0'

     sourceCompatibility = 11
     allprojects {
       repositories {
         maven { url 'https://maven.aliyun.com/repository/public/' }
         maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }

         mavenCentral()
       }
     }


     repositories {
       mavenCentral()
     }

     // See https://github.com/JetBrains/gradle-intellij-plugin/
     intellij {
       version = '2021.1.3'
       plugins = ['com.intellij.java']

     }

     buildSearchableOptions {
       enabled = false
     }

     patchPluginXml {
       version = project.version
       sinceBuild = '211'
       untilBuild = '213.*'
     }

    tasks.withType(JavaCompile) {
        options.encoding = "UTF-8"
    }

• plugin.xml idea插件的配置文件,用于定义插件的描述信息以及 插件注册信息

  <idea-plugin>
      <id>org.example.ideaPluginTest</id>
      <!--    插件名称-->
      <name>Plugin display name here</name>
      <!--    作者相关信息-->
      <vendor email="support@yourcompany.com" url="http://www.yourcompany.com">YourCompany</vendor>
      <!--插件的介绍和描述信息-->
      <description><![CDATA[
      Enter short description for your plugin here.<br>
      <em>most HTML tags may be used</em>
      ]]></description>
      <!--  该插件依赖的组件和插件信息,当前依赖idea平台基础库  -->
      <!-- please see https://plugins.jetbrains.com/docs/intellij/plugin-compatibility.html
           on how to target different products -->
      <depends>com.intellij.modules.platform</depends>
      <!-- 注册 idea 的扩展点   -->
      <extensions defaultExtensionNs="com.intellij">
          <!-- Add your extensions here -->
      </extensions>
      <!-- 注册 idea 的菜单相关操作项   -->
      <actions>
          <!-- Add your actions here -->
  
      </actions>
  </idea-plugin>
  

2. 添加一个菜单选项

1. 通过DevKit 向菜单添加一个自己的操作项

   image-20211221200702480

2. 向编辑器popup上添加一个操作项

   image-20211221200946886

   确认添加后,会自动向plugin.xml 文件中添加一条action记录并创建相关的操作类

   <idea-plugin>
       <id>org.example.ideaPluginTest</id>
       <!--    插件名称-->
       <name>Plugin display name here</name>
       <!--    作者相关信息-->
       <vendor email="support@yourcompany.com" url="http://www.yourcompany.com">YourCompany</vendor>
       <!--插件的介绍和描述信息-->
       <description><![CDATA[
       Enter short description for your plugin here.<br>
       <em>most HTML tags may be used</em>
       ]]></description>
       <!--  该插件依赖的组件和插件信息,当前依赖idea平台基础库  -->
       <!-- please see https://plugins.jetbrains.com/docs/intellij/plugin-compatibility.html
            on how to target different products -->
       <depends>com.intellij.modules.platform</depends>
       <!-- 注册 idea 的扩展点   -->
       <extensions defaultExtensionNs="com.intellij">
           <!-- Add your extensions here -->
       </extensions>
       <!-- 注册 idea 的菜单相关操作项   -->
       <actions>
           <!-- Add your actions here -->
           <action id="myAction" class="com.test.MyAction" text="自定义操作" description="我的自定义操作">
               <add-to-group group-id="EditorPopupMenu" anchor="first"/>
           </action>
       </actions>
   </idea-plugin>
   

   public class MyAction extends AnAction {
   
       @Override
       public void actionPerformed(AnActionEvent e) {
           // TODO: insert action logic here
       }
   }
   

3. 添加该操作的处理事件,中文部分一定要通过Alt+Enter 选择转为拉丁语 ,变成Unicode码格式,要不会显示乱码

   public class MyAction extends AnAction {
   
      @Override
      public void actionPerformed(AnActionEvent e) {
          //显示消息提示框
          Messages.showInfoMessage("\u6211\u7684\u81EA\u5B9A\u4E49\u64CD\u4F5C",
                  "\u63D0\u793A\u6807\u9898");
     }
   }
   

4. 调试和验证插件功能

   image-20211221201302050

   双击执行gradle的 runide 任务就会自动启动一个自动安装好当前开发的插件的idea 环境

   我们可以在这个idea 进行相关的运行测试和调试相关功能

5. 在新启动的IDEA 中创建一个空的项目,并新建一个文件,在文件中右击编辑区域,就可以看到我们自己注册上的菜单功能

3. 打包IDEA 插件并生成插件包

在gradle中执行buildPlugin操作,gradle编译生成zip包,只要按照对应的zip包插件就行
