idea2023开发插件入门

创建工程

通过 idea plugin 来创建工程
在这里插入图片描述

修改开发语言

默认创建的工程是用scala开发的，但是我不会，就会java,所以改成java创建

build.gradle.kt 为 build.gradle
settings.gradle.kt 为 settings.gradle

build.gradle修改为以下:

plugins {id("java")//id("org.jetbrains.kotlin.jvm") version "1.8.21"id("org.jetbrains.intellij") version "1.13.3"
}group = "com.wtf"
version = "1.0-SNAPSHOT"repositories {maven { url 'https://maven.aliyun.com/repository/central/'}maven { url 'https://maven.aliyun.com/repository/public/' }maven { url 'https://maven.aliyun.com/repository/google/' }maven { url 'https://maven.aliyun.com/repository/jcenter/'}maven { url 'https://maven.aliyun.com/repository/gradle-plugin'}mavenCentral()
}// Configure Gradle IntelliJ Plugin
// Read more: https://plugins.jetbrains.com/docs/intellij/tools-gradle-intellij-plugin.html
intellij {version.set("2022.2.5")type.set("IC") // Target IDE Platform
}tasks.withType(JavaCompile) {options.encoding = 'UTF-8'sourceCompatibility = "17"targetCompatibility = "17"options.compilerArgs += ['-Xlint:unchecked', '-Xlint:deprecation', '-parameters']
}//以下原始的都不要
/*
tasks {// Set the JVM compatibility versionswithType<JavaCompile> {sourceCompatibility = "17"targetCompatibility = "17"}*/
/* withType<org.jetbrains.kotlin.gradle.tasks.KotlinCompile> {kotlinOptions.jvmTarget = "17"}*//*patchPluginXml {sinceBuild.set("222")untilBuild.set("232.*")}*/
/*    signPlugin {certificateChain.set(System.getenv("CERTIFICATE_CHAIN"))privateKey.set(System.getenv("PRIVATE_KEY"))password.set(System.getenv("PRIVATE_KEY_PASSWORD"))}publishPlugin {token.set(System.getenv("PUBLISH_TOKEN"))}*//*}
*/

第一次编译会下载IC-idea,大概 600多M

helloworld插件开发

在这里插入图片描述

idea 会创建一个 ShowHello 类

public class ShowHello extends AnAction {@Overridepublic void actionPerformed(AnActionEvent e) {// TODO: insert action logic hereMessages.showMessageDialog("hello idea plugin","这里标题",Messages.getInformationIcon());}
}
