log4j2 自定义附加程序在 proguard 后无法工作

Question

应用 proguard 后出现以下错误。
用于 proguard 的 -injar 没有收到错误。
通过跳过所有类（包括混淆中混淆的依赖项）来检查错误。 使用 maven- assembly-plugin 创建具有依赖项的 injar 。

                            final boolean ignoreExceptions) {
        super(name, filter, layout, ignoreExceptions);
    }

    @PluginFactory
    public static TextAreaAppender createAppender(
            @PluginAttribute("name") String name,
            @PluginElement("Layout") Layout<? extends Serializable> layout,

确保配置中的包被正确引用。 仅当包引用错误时，我才在您的代码中收到此异常。
