Codenameone：集成Codename One本機數據傳輸庫時出現內部錯誤

我試圖將本地數據傳輸的cn1lib集成在Extensions-Page上。不幸的是，當這個庫集成時，會出現一些構建錯誤：缺少一些awt-classes（例如import java.awt.Component;）。Codenameone：集成Codename One本機數據傳輸庫時出現內部錯誤

我不知道，完成構建時缺少的是什麼。

下面是完整的控制檯，輸出與構建錯誤：

你是如何安裝的圖書館嗎？通過Codename One設置或其他方式？ –

通過設置部分 - 包括「刷新庫」的調用 – KlausHeywinkel

你能列出你得到的確切錯誤嗎？右擊項目並進行構建時，你會得到它們嗎？ –

在當前版本的Eclipse build.xml模板中似乎存在一個錯誤。我已經應用了將包含在下一個插件更新中的修復程序。同時，您需要對build.xml文件進行一些小改動。

在你的build.xml 170線，有一個javac的電話：

<javac destdir="native/internal_tmp" compiler="modern" 
      source="1.8" 
      target="1.8" 
      bootclasspath="lib/CLDC11.jar" 
      classpath="lib/CodenameOne.jar:${build.classes.dir}:lib/impl/cls:build/tmp"> 
      <src path="native/javase"/> 
      <src path="lib/impl/native/javase"/> 
     </javac>

取出bootclasspath=行，所以你最終：

<javac destdir="native/internal_tmp" compiler="modern" 
      source="1.8" 
      target="1.8" 
      classpath="lib/CodenameOne.jar:${build.classes.dir}:lib/impl/cls:build/tmp"> 
      <src path="native/javase"/> 
      <src path="lib/impl/native/javase"/> 
     </javac>
