我突然发现构建错误使用Maven来构建一个使用com.fasterxml.jackson.core的JavaFX应用程序：jackson-databind，我没有更新POM大约3-4周，因此我感到很困惑这突然发生的原因。
整个错误消息为：
com.fasterxml.jackson.core的pOM：jackson-databind：jar：2.3.2无效，传递依赖（如果有）将不可用，启用调试日志记录以获取更多详细信息
工件org.apache.commons：commons-io：jar：1.3.2已被重定位到commons-io：commons-io：jar：1.3.2
我更新了com.fasterxml.jackson.core＆amp; commons-io，现在建造时我得到了：
com.fasterxml.jackson.core的pOM：jackson-databind：jar：2.3.2无效，传递依赖（如果有）将不可用，启用调试日志记录以获取更多详细信息
当我从NetBeans运行应用程序时，我得到：
--- exec-maven-plugin：1.2.1：exec（default-cli）@ Video_Assembler --- 错误：无法找到或加载主类com.conuretech.video_assembler.MainApp
这是我的POM.xml：

我不知道如何进一步解决“com.fasterxml.jackson.core：jackson-databind：jar：2.3.2”问题，我已经使用<mainClass>com.conuretech.video_assembler.MainApp</mainClass>声明了主类，任何帮助将不胜感激
