Java “线程中的异常”；“主要”；NoClassDefFoundError，使用maven shade插件打包

java maven jar log4j

Java “线程中的异常”；“主要”；NoClassDefFoundError，使用maven shade插件打包,java,maven,jar,log4j,Java,Maven,Jar,Log4j,我使用mvn-package来打包uber-jar。pom.xml是： <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> &l

我使用

mvn-package

来打包uber-jar。pom.xml是：

若要修复CNFE，请尝试在pom.xml中添加log4j依赖项。@Josepraven是的，我猜log4j api存在冲突。
