IntelliJ IDEA 2022.2 (Ultimate Edition) plugin插件开发

1. 创建IDE Plugin工程

2.修改工程iml文件

这里默认创建的iml文件module type有问题，需要修改为PLUGIN_MODULE

<module type="PLUGIN_MODULE" version="4">
  <component name="DevKit.ModuleBuildProperties" url="file://$MODULE_DIR$/resources/META-INF/plugin.xml" />
  <component name="NewModuleRootManager" inherit-compiler-output="true">
    <exclude-output />
    <content url="file://$MODULE_DIR$">
      <sourceFolder url="file://$MODULE_DIR$/src" isTestSource="false" />
      <sourceFolder url="file://$MODULE_DIR$/resources" type="java-resource" />
    content>
    <orderEntry type="jdk" jdkName="IntelliJ IDEA IU-222.3345.118" jdkType="IDEA JDK" />
    <orderEntry type="sourceFolder" forTests="false" />
  component>
module>

3.修改build.gradle.kts文件

替换为aliyun镜像加快构建速度

repositories {
    maven("https://maven.aliyun.com/nexus/content/groups/public/")
}

升级org.jetbrains.intellij 版本到最新1.9.0版本，避免采坑

plugins {
    id("java")
    id("org.jetbrains.intellij") version "1.9.0"
}

4. build项目

可能因为github请求超时导致如下报错，忽略即可

> Configure project :
[gradle-intellij-plugin :MyPlugin] Cannot resolve the latest Gradle IntelliJ Plugin version
org.gradle.api.GradleException: Cannot resolve the latest Gradle IntelliJ Plugin version
	at org.jetbrains.intellij.utils.LatestVersionResolver$Companion.fromGitHub(LatestVersionResolver.kt:31)
	at org.jetbrains.intellij.IntelliJPlugin.checkPluginVersion(IntelliJPlugin.kt:135)

这里为了节省时间，也可以在第一次build成功后，为了避免后面github请求等待超时时间过长，可以设置为离线模式进行build

5. run起来

不用添加plugin configution 配置，直接点击gradle run plugin脚本即可

启动成功！

6. 写个demo

右键直接使用Plugin DevKit插件 new一个Action

生成的action支持直接跳转到对应plugin.xml中配置的地方（对应已经生成好了）


补充action代码，测试验证下PsiElement对象获取

public class MyAction extends AnAction {

    @Override
    public void actionPerformed(AnActionEvent e) {
        // TODO: insert action logic here
        Project project = e.getProject();
        PsiElement element = (PsiElement)e.getData(CommonDataKeys.PSI_ELEMENT);
        Messages.showInfoMessage(element.toString(), "Caret Parameters Inside The Editor");
    }
}

点击Run Plugin ，启动完成后Tools工具栏对应出现新增MyAction按钮

点击后，弹出PsiElement非空，说明跑通了
