使用poi-ooxml打破資源提供

Question

我想用外部配置文件製作jar文件。在使用poi-ooxml庫之前一切正常。之後，我遇到了資源提供問題。我用接下來的pom.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<project xmlns="http://maven.apache.org/POM/4.0.0" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      <artifactId>core</artifactId> 
      <version>LATEST</version> 
     </dependency>  
    </dependencies> 
</project> 

我沒有在這條線：

LogManager.getLogManager().readConfiguration(MethodHandles.lookup().lookupClass().getClassLoader().getResourceAsStream(fileName)); 

的getResourceAsStream返回null，但是當我從POM文件中刪除POI-OOXML依賴一切工作正常。

問題出在Apache Assembly plugin中。改爲使用Apache Shade插件。 https://maven.apache.org/plugins/maven-shade-plugin/
