【问题描述】：

我正在将应用程序从 Oracle Java 8 升级到 openjdk Java 16，但无法让 ant 任务 javac2 工作。我收到了错误

An Ant BuildException has occured: Forms instrumentation failed

原因

Class not found: com.intellij.uiDesigner.core.Spacer

完整的错误信息是：

我可以在forms_rt.jar 中看到类com.intellij.uiDesigner.core.Spacer，所以我不明白为什么会出现错误。是因为我使用的是 Java 16 吗？我的 Idea 版本是 212.4746.92。

干杯，

迈克

【问题讨论】：

  • 请添加完整的异常堆栈跟踪。
  • 我编辑了我的问题并使用堆栈跟踪对其进行了更新。

标签： java intellij-idea java-16 maven-ant-tasks


【解决方案1】：

通过下载ideauidesigner-maven-plugin的源代码并创建一个本地版本解决了这个问题：

  • 适用于 java 16
  • 使用我的 Intellij Idea 安装中与表单相关的 jar，而不是公共 maven 存储库中提供的那些

干杯，

迈克
