Plugin: ClassNotFoundException: org.tukaani.xz.FilterOptions

[Frank Heinze]

Hello,

We have a plugin we wrote ourselves to check the attachments uploaded to a Jira ticket. It can currently handle ZIP files, and now I wanted to extend it to include 7zip.
To do this, I am using the dependency “org.apache.commons/commons-compress,” which in turn requires “org.tukaani/xz”.

<dependency>
 <groupId>org.apache.commons</groupId>
 <artifactId>commons-compress</artifactId>
 <version>1.27.1</version>
 <scope>provided</scope>
</dependency>
<dependency>
 <groupId>org.tukaani</groupId>
 <artifactId>xz</artifactId>
 <version>1.10</version>
 <scope>compile</scope>
</dependency>

Setting the scope of the dependency “org.tukaani/xz” to “provided” did not help either. However, the packages were definitely included in the actual jar, regardless of which scope I used.

I have also integrated this, but I am getting the following error message from Jira

java.lang.ClassNotFoundException: org.tukaani.xz.FilterOptions

I also tried adding the packages from “tukaani” to the export and import settings. I tried several different spellings. But that didn't help at all.

<!-- Add package to export here -->
<Export-Package>
 org.tukaani.xz*
</Export-Package>

<!-- Add package import here -->
<Import-Package>
 org.tukaani.xz*,
 *;resolution:=optional
</Import-Package>

And when I look at the OSGI control, the packages are also pulled during import and export.

Does anyone have any idea what else I can do?
I have some experience with Spring, but not in depth.
