maven冲突

package macros contains object and package with same name:blackbox one of them needs to be removed from classpath

这有可能是scala中的Object和添加的依赖有冲突,比如,本次遇到的冲突就是和下面的依赖有冲突,跟scope标签没关系,也跟scala编译器的配置没关系

maven 打包后,通过可以得到src/main/resources下的资源,这是将src/main/resources下的资源打入jar包后,通过以下方法得到

PropertyConfigurator.configure(this.getClass().getClassLoader().getResource("log4j.properties"));

如果maven打包后,没有把src/main/resources下的资源打入jar包,从另外的配置文件读取,是这样的,读取的jar里的

String path="conf/log4j.properties";
InputStream in=this.getClass().getClassLoader().getResourceAsStream(path);

这里写图片描述
