maven-shade-plugin排除声明为依赖的jar

提问于

我正在使用maven打包一个带阴影的jar文件 . 我在其他帖子上搜索了这个,没有找到答案 . 我也没有使用提供的元素 .

我将log4j-core包含在pom.xml中作为依赖项,但是当maven-shade-plugin构建时,它会排除该依赖项中的类吗?我下载了jar的V2.5并检查,包和类都在其中 .

我不得不排除一些org.slf4j类,但这不应该影响这一点 .

这是pom.xml的相关部分

这是堆栈跟踪:

    最后我放弃了maven-shade-plugin并使用了maven-assembly-plugin,它似乎可以工作并最终得到一个可行的jar .
