从任何java应用程序调用自己的eclipse插件方法 [英] call a own eclipse plugin method from any java application

问题描述

我想执行以下操作：

创建一个自己的Eclipse插件，（例如）只有一个方法sayHello显示一条消息hello world

Create a own Eclipse Plugin, that (for example) just has one method "sayHello" that displays a message "hello world".

所以很好。

但是现在我想让用户，有我的插件安装，从他们的java代码调用这个方法。这样的：

But now I want to let the users, that have my plugin installed, call this method from their java code. something like that:

//[...]
org.jjoe64.my_eclipse_plugin.Plugin.sayHello(); // of course this won't work...
//[...]

<有没有人有这样的想法？我认为这更复杂一些...

has anybody an idea how to do this? I think it's a little bit more complicate ...

推荐答案

基本上你想调用一个运行来自Eclipse的代码编译和运行的插件。因为这是两个独立的过程，所以没有简单的方法直接调用一个方法。

Basically you want to call a running plug-in from code compiled and running from Eclipse. Because these are two separate processes there is no simple way to directly invoke a method.

一个简单的解决方案是让你的插件轮询是在用户的工作区。

One simple solution is to have your plug-in poll a temporary file it creates in the user's workspace.

class Plugin {
   void Activate() {
      while (true)
         if (temporaryFile.hasChanged())
            doSomething();
   }
}

创建用户导入到他们的项目的库。他们在该库中调用更新文件的函数：

Create a library your user imports to their project. They call a function in that library that updates the file:

class PluginCaller {
    static void sendMessageToPlugin(String message) {
         temporaryFile.append(message);
    }
}

当您的插件看到有变化，它的作用就好像该方法被调用。

When your plug-in sees there has been a change, it acts as though the method was called.
