[英]maven-shade-plugin is excluding jar that is declared as a dependency
我正在使用 maven 打包一個帶陰影的 jar 文件。 我瀏覽了其他帖子,但沒有找到答案。 我也沒有使用提供作為元素。
我將該 log4j-core 作為依賴項包含在 pom.xml 中,但是當 maven-shade-plugin 構建時,它排除了該依賴項中的類? 我下載了jar的V2.5並檢查,包和類都在里面。
我不得不排除一些 org.slf4j 類,但這不應該影響到這一點。
這是 pom.xml 的相關部分

這是堆棧跟蹤:

最后我放棄了maven-shade-plugin並使用了maven-assembly-plugin,它似乎可以工作並最終得到一個可行的jar。
由於https://issues.apache.org/jira/browse/LOG4J2-673中報告的問題,我也遇到了類似的問題。
感謝這篇文章http://www.codepreference.com/2017/02/how-to-fix-log4j2-problem-with-maven-shade-plugin.html建議包含/傳遞log4j-core和log4j-classic外部,它對我有用。
