【中文标题】Proguard Maven 插件不使用指定的 Proguard 版本

【英文标题】：Proguard Maven Plugin Doesn't Use The Specified Proguard Version

【发布时间】：2021-10-30 20:35:28

【问题描述】：

Proguard Maven 插件未使用指定的 proguard 版本，因此我收到以下错误：(Can't process class [com/sun/javafx/charts/ChartLayoutAnimator.class] (Unsupported class version number [54.0] (maximum 52.0, Java 1.8)))

如果您知道如何强制插件使用更新的版本，请告诉我。

【参考方案1】：

事实证明，您必须在打开配置之前关闭执行元素。

【讨论】：

是否有任何其他要求需要考虑才能正确运行？当我使用插件时没有任何反应。没有生成文件。

@chitgoks 很多事情可能出错了，我建议通过在 mvn 命令后添加“-X”标志来调试它以运行插件。它会打印出详细的日志。
