+# Bean Copy (IntelliJ IDEA 插件)
+
+一键把源 JavaBean 的属性值，通过 get/set 方法复制到目标 JavaBean。
+
+## 功能
+
+在一个方法内写：
+
+```java
+A a = new A();
+B b = new B();
+```
+
+按下 **Alt + Insert**（Generate）或 **右键菜单**，选择 **Bean Copy...**，
+在弹出的对话框中选一个 **Source Bean（读）** 和一个 **Target Bean（写）**，
+插件就会在光标处自动生成：
+
+```java
+b.setXxx(a.getXxx());
+b.setYyy(a.getYyy());
+// ... 每个在目标类中有同名 setter 的属性
+```
+
+- 自动识别 `getXxx()`、`isXxx()`（布尔）等 getter
+- 用 `PropertyUtil` 的属性名匹配做 get/set 配对，`get / set / is` 前缀与大小写自动处理
+- 只复制「源有 getter 且目标有同名 setter」的属性
+- 对话框的两个下拉框**可编辑**：既能下拉选择，也能直接输入变量名
+- 若光标正位于某个变量上，打开对话框时会**自动预填**源/目标为那个变量
+- 光标**选中**变量触发时，生成的代码会**替换选区**，去掉先前选中的变量名
+- 提供「**同时复制父类(继承)的属性**」复选框（默认不勾选），勾选后连同父类/接口继承的 getter/setter 一起复制
+
+## 环境要求
+
+- **JDK 21**（IntelliJ 2025.x 平台基于 JDK 21 编译）
+- **IntelliJ IDEA**（开发/构建时会自动下载 2025.2 平台依赖）
+
+## 构建技术栈
+
+- 构建脚本位于 `build.gradle.kts` / `settings.gradle.kts` / `gradle.properties`
+- 使用 **IntelliJ Platform Gradle Plugin 2.x**（`org.jetbrains.intellij.platform`）
+- 目标平台 `intellijIdea("2025.2.6.2")`，支持 **2025.2+**（`since-build = 252`）
+- 额外引入内置 `com.intellij.java` 插件，使 `PsiClass / PsiMethod / PsiJavaFile` 等 Java PSI 可被编译
+- **Gradle 9.5** wrapper 已内置，无需自行安装 Gradle
+
+## 构建
+
+用 IntelliJ IDEA 打开本项目，等待 Gradle 同步完成；
+或命令行（项目自带 wrapper，无需本机安装 Gradle）：
+
+```bash
+./gradlew build              # 产出 build/distributions/idea-plugin-copy-bean-1.0.0.zip（已让 build 依赖 buildPlugin）
+./gradlew buildPlugin        # 等价：仅产出插件 zip
+```
+
+> 说明：`buildPlugin` 是 IntelliJ 插件专属任务，默认不会挂到标准 `build` 生命周期上；
+> 项目里已通过 `tasks.named("build") { dependsOn("buildPlugin") }` 让 `./gradlew build` 也能直接产出可安装的 zip。
+
+## 运行调试
+
+在 IDEA 的 Gradle 任务里（或命令行）运行：
+
+```bash
+./gradlew runIde             # 启动一个带本插件的临时 IDE 实例进行调试
+```
+
+> 首次运行会自动下载平台并全量索引，耗时较长（几十分钟），属正常现象；后续会复用配置缓存/构建缓存，快很多。
+
+## 安装到正式 IDE
+
+1. 执行 `./gradlew build` 或 `./gradlew buildPlugin`
+2. 打开 IDEA → Settings → Plugins → ⚙ → Install Plugin from Disk…
+3. 选择 `build/distributions/idea-plugin-copy-bean-1.0.0.zip` 并重启 IDE

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/3d91ce3b8caaf77ad09f381f43615b715b53f72c/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
