新建插件项目之后，可以看到plugin.xml 项目有一些报错
修改plugin.xml 的内容如下
<idea-plugin>
<id>com.your.company.unique.plugin.id</id>
<name>我的代码检视插件</name>
<version>1.0</version>
<vendor email="support@126.com" url="http://www.xumenger.com">个人开发者</vendor>

【New】->【Plugin DevKit】，在SourceCheck 项目中新增一个Action，一切还是从HelloWorld 开始
Action ID 保证不重复即可，选择HelpMenu（Help）表示这个Action 在Help 菜单的里面
创建完成之后，可以看到plugin.xml 自动新增了一个HelloWorld 的Action
自动创建的HelloWorld 的代码如下
package com.xum;
import com.intellij.openapi.actionSystem.AnAction;
import com.intellij.openapi.actionSystem.AnActionEvent;
public class HelloWorld extends AnAction {
@Override
public void actionPerformed(AnActionEvent e) {
// TODO: insert action logic here
}
}
然后编写测试代码如下
package com.xum;
import com.intellij.openapi.actionSystem.AnAction;
import com.intellij.openapi.actionSystem.AnActionEvent;
import com.intellij.openapi.actionSystem.PlatformDataKeys;
import com.intellij.openapi.project.Project;
import com.intellij.openapi.ui.Messages;
public class HelloWorld extends AnAction {
@Override
public void actionPerformed(AnActionEvent e) {
Project project = e.getData(PlatformDataKeys.PROJECT);
Messages.showMessageDialog(project,"Hello,World","Hello World", Messages.getInformationIcon());
}
}
点击运行，可能出现这样的报错

参考IDEA 插件开发（一）：菜单及气泡通知，忽略这个报错
从 JDK 9 开始，已经不提供包 com.apple.eawt 和 com.apple.eio，取而代之的是 java.awt.desktop。不知道哪里的代码用的还是 JDK 8，目前不影响，先不用管
运行之后会打开一个新的IDEA 程序，比如创建一个Meaven 项目，并且新增一个Java文件，然后在【Help】菜单下面可以看到有一个【Hello World】的选项。点击后可以看到下面的弹出框
OK，基于这些参考的文章，现在开发一个IDEA 插件的流程基本就是这样的，后续的文章我们就基于IDEA 插件做更多的功能
