Question

I have a maven project in which the some xlsx files get generated after the project run phase. These excel sheets are used by some other projects also. So I need to publish these excel sheet artifacts to remote|local repository.

I tried with the deploy plugin’s deploy-file goal. But after deploying the excel sheet as a jar in repo, I tried extracting the jar and I could see the excel sheet got corrupted. Excel sheet converted to several XML files. ( Sheet1.xml, Sheet2.xml ..)

Maven command :-

mvn clean deploy:deploy-file -Durl=file:///C:\repository -Dfile=Series.xlsx -DpomFile=seriesXL.pom

SeriesXL.pom:-

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"

            <artifactId>poi</artifactId>

        </dependency>
    </dependencies>

</project>

Please help me to resolve this issue. All inputs are appreciated.

Answer 1

Microsoft is trying to push new file formats that are using ZIP and XML in their office suites. This method reduces the size of the file by around 50%.

Reference

That means the excel file is actually a packed file of different xmls and other metadata informations.

I have done a work around to resolve the issue:

1. After excel sheet generation, I have added that file to a zip (SeriesXL.zip), using java.util.zip.ZipEntry.

2. Then deploy the zip file using the command

   mvn clean deploy:deploy-file -Durl=file:///C:\repository -Dfile=SeriesXL.zip -DgroupId=com.test.pjt -DartifactId=seriesXL -Dversion=1.0 -Dpackaging=jar
   

I am able to successfully deploy the SeriesXL.jar in local repository and while extracting the jar, I could see the original version of the Excel sheet, not just a bundle of XML files.

BTW Thanks Dunni for your support.
