Bug#964706: jabref: FTBFS: OOUtil.java:13: error: package com.sun.star.beans does not exist

[Rene Engelhard]

Hi,

just saw this bug while working on a patch which properly documents the
library dependencies (aka "replace libreoffice-java-common in
build-depends with explicit libjuh-java, libjurt-java, libridl-java, libunoil-java
and add these as explicit Depends/Recommends in addition to
libreoffice-java-common)...

All needed libs are installed...

So they are found there...

... but not here anymore.

All of thse libs above are now dummy libs for liblibreoffice.jar. They
are empty and just contain Class-Path:

root at frodo:/usr/share/java# unzip juh.jar
Archive:  juh.jar
   creating: META-INF/
  inflating: META-INF/MANIFEST.MF
root at frodo:/usr/share/java# cat META-INF/MANIFEST.MF
Manifest-Version: 1.0
Class-Path:  libreoffice.jar
Solar-Version: 7.0.0.2
UNO-Type-Path:
Created-By: 11.0.7 (Debian)

So why does the build not find it? (It might be that the Maven POMs
don't specify that variable properly, but should that affect actual
compilation? Is Class-Path: used?)

[ When I first saw this I wondered whether the "wrong" Class-Path: in
juh.jar might have to do with it. But writer2latex built fine with that
and 1:7.0.0~rc2-1 (which fixed the Class-Path:) doesn't help here
either.]

As a workaround one might patch jabref to use libreoffice.jar directly
- which is the library to use anyway. (the others are still packaged for
compatibility with old packages and third-party stuff which doesn't know
about libreoffice.jar...) but...
