Emmanuel Bourg commented on COMPRESS-275:
-----------------------------------------
org.tukaani:xz is a dependency of commons-compress, importing the transitive
dependencies of the libraries you use is generally a good idea :) Dependency
managers like Maven and Ivy do it for you automatically.
Note that in the next release this dependency will become optional, so you'll
have to import it explicitly if you use the XZ functionalities. We have to
document that properly.
> Packing problem? NoClassDefFoundError: org/tukaani/xz/FilterOptions

> Key: COMPRESS-275
> URL: https://issues.apache.org/jira/browse/COMPRESS-275
> Project: Commons Compress
> Issue Type: Bug
> Components: Compressors
> Affects Versions: 1.8
> Environment: Mac OS 10.9 w/ Java 6, 7
> Reporter: Cyrille Artho
> Attachments: Report2.java
>
>
> I can compile the code but not execute it because a class seems to be
> missing. I guess the class is not part of the API but used internally.
> When I use the constructor of
> org.apache.commons.compress.compressors.xz.XZCompressorOutputStream, then I
> need org/tukaani/xz/FilterOptions at run-time, which is not part of
> apache-compress.jar.
> It's at least not immediately obvious that other .jar files are required to
> use some of the functionality. Maybe this was intended to be included in the
> distribution?
