Eclipse插件：傳遞命令行參數

Question

目前我傳遞命令行參數來調用程序。我正在展示一個小的代碼片段供您參考。

public class Main { 
    public static void main(String[] args) throws Exception { 

     GlobalVariable.activity = args[0]; 
     GlobalVariable.templatePath = args[1]; 
     .... 

     } 

要調用上述程序，我從Eclipse傳入以下命令。

現在，我正在嘗試開發一個從Java程序本身調用此命令的eclipse插件。要開發一個插件，我也做了以下內容：

1. 的Eclipse（新建 - >項目 - > Eclipse插件項目），項目名稱爲「org.example.helloworld」
2. 我選擇「插件與彈出向上菜單「模板。
3. 現在，我寫了下面的代碼在「NewAction.java」命令行參數傳遞給我的主文件，如上圖所示」

public void run(IAction action) { 
     String args[] = new String[2]; 
     args[0] = "compile-vocab-spec"; 
     args[1] = "C:\\Template\\"; 

     try { 
      Main.main(args); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 

我的問題是 - 我無法調用Main.java文件，這種技術有什麼問題？請歡迎任何其他選擇。請讓我知道以防萬一您需要更多信息以進一步清晰化

我看到以下消息控制檯我運行代碼。

Answer 1

在你的插件所需的罐子必須在MANIFEST.MF在Bundle-Classpath進入上市。

要做到這一點，打開MANIFEST.MF編輯器，在'運行時'選項卡上添加jar到'Classpath'部分。

結果可能會是這樣的：

的 ''入口是爲插件文件，然後我有一個'lib'文件夾中有3個罐子。

還要確保jar被列在'build.properties'文件中，以便它們被包含在最終的插件jar中。
