GuiBuilder编译时，每两次尝试就会产生一次JAXB错误

编程语言 2026-07-09

IntelliJ IDEA 2025.2.3，Java JDK与语言级别11，文件使用jDeploy创建，cn1版本7.0.236；在更新到最新版时也存在同样的问题。

我可以使用guibuilder命令 mvn cn1:guibuilder -DclassName=com.github.name.untitled4.gui.Test1 成功创建（create-gui-from）并编辑一个GUI表单，但在构建它的时候，会出现以下错误：

timeStr=1.0.0-1778496107786-1778496447286, lastTime=1.0.0-1778496107786-1778496181036

不过第二次编译时，它允许我进入模拟器，因为它会检查 timeStr 是否与上次相同（错误步骤），所以它显示空表单/错误表单，因为新改动没有被编译。

我的 .gui（以及它们对应的 .java）文件都在包 .gui 的 common 文件夹内，.gui 位于 guibuilder 文件夹，.java 位于 java 文件夹。我认为这不应该影响任何事情。带有 runApp 方法的Java文件不在任何额外的包中。

我尝试过：

  • 删除 CodeNameOneBuildClient.jar —— 它返回一个错误，因为没有找到 CodeNameOneBuildClient.jar，但构建GUI表单需要它。

  • 使用 mvn:clean 去掉 target 文件夹然后让它重新构建 —— 它不工作，因为 .java 文件未与所需的GUI内容一起构建。

  • 复制该文件然后在复制的文件上尝试 —— 这可行，但一段时间后就不再工作，因为它返回同样的错误。

  • 手动输入修改后的组件 —— 可行，但非常非常繁琐，我宁愿不这样做。

解决方案

我们正在尽量在各处移除jaxb，以避免这类问题。构建客户端jar的最新版不应包含它，您可以从以下地址下载二进制文件 https://github.com/codenameone/CodenameOne/raw/refs/heads/master/maven/CodeNameOneBuildClient.jar
