Java Card 3.0.x Eclipse插件创建小程序报JAXBException求助

问题背景 #

之前用Eclipse+Java Card插件开发小程序，切换到Java Card 3.0.x版本时，安装了Oracle官网的运行时包java_card_devkit_tools-bin-v24.0-b_57-20-FEB-2024.zip和对应Eclipse插件java_card_devkit_eclipse_plugin-bin-v24.0-b_50-20-FEB-2024，但创建新Java Card小程序的最后一步，项目向导报错：

创建Java Card项目时出错。javax/xml/bind/JAXBException

查资料得知，这个问题是因为新版本Java运行时移除了JAXB组件，但Oracle的Java Card插件依赖它。网上大部分解决方案是修改应用源码（比如Spring项目）或通过Maven/Gradle添加依赖，但这个错误出在IDE内部，没法修改Eclipse或插件的源码。有人建议安装eclipse-ee4j，但下载后不知道怎么添加到Eclipse里，而且目前还没创建出项目，没有可修改的源码。

环境信息 #

• Eclipse版本：2024-03 (4.31.0)，Build id:20240307-1437
• Java版本：18.0.2（Oracle）
• 测试过的另一个环境：Eclipse IDE for Enterprise Java and Web Developers，Java 17.0.10（Eclipse Adoptium），同样报错

解决方案 #

方案1：使用Java 8运行Eclipse #

JAXB是Java 8的内置组件，用Java 8启动Eclipse可以直接解决依赖问题：

1. 下载Java 8（Oracle或OpenJDK版本均可）
2. 找到Eclipse安装目录下的eclipse.ini文件，用文本编辑器打开
3. 在-vmargs行之前添加Java 8的javaw.exe路径，示例：

   -vm
   C:\Program Files\Java\jdk1.8.0_391\bin\javaw.exe
   

4. 保存文件后重启Eclipse，再尝试创建Java Card项目

方案2：给Eclipse添加JAXB模块参数（Java 11+适用） #

如果不想更换Java版本，可以通过修改Eclipse启动参数引入JAXB模块：

1. 打开eclipse.ini文件，在-vmargs行下方添加：

   --add-modules=java.xml.bind
   

2. 保存并重启Eclipse

方案3：安装Eclipse EE4J插件 #

按照以下步骤安装EE4J插件：

1. 打开Eclipse，点击顶部菜单栏的Help -> Eclipse Marketplace
2. 在搜索框输入Eclipse EE4J，找到对应插件后点击Install
3. 按照提示完成安装，重启Eclipse后再尝试创建项目
