method one:
Directly modify the following parts in the pom file
<artifactId>excelreport</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>excelreport</name>
<description>excelreport</description>
After the modification is complete, click the package in maven, and you can see the generated jar package, whose name has changed.
If the IDEA directory has not changed, you can refresh the directory in file.
Method Two:
Instead of the modification method in method 1, you can also specify the name of the jar package directly in the build.
