I tried to build this package with target: rawhide.

Spec URL: http://copr-dist-git.fedorainfracloud.org/cgit/nrechn/XtreemFS/xtreemfs.git/plain/xtreemfs.spec?id=7925e58c1670dfb4040e23b9ff048c2439fa5d59

Hi
there are more prebuilt libraries, and they must be removed
using:
find . -name "*.class" -delete
find . -name "*.jar" -delete
must be removed also:
BuildRoot:      %{_tmppath}/%{name}-%{version}-build
field Group
%defattr(-,root,root,-)
You must use make %{?_smp_mflags} instead of make %{?jobs:-j%jobs}
You must use %license macro for LICENSE file
You must use rpm macros instead of hardcoding the directories e.g. %{_javadir}/XtreemFS.jar
You must use:
Requires:       java-headless instead of Requires:       jre >= 1.6.0
or add a/some comment/s, in the spec file, why is necessary jre
You must use: License:        BSD instead of License:        BSD-3-Clause

Other problem:
You must use:
Source0:        http://www.xtreemfs.org/downloads/XtreemFS-%{version}.tar.gz
or
Source0:        https://github.com/xtreemfs/xtreemfs/archive/%{version}.tar.gz

instead of Source0:        XtreemFS-%{version}.tar.gz

Thanks your comments.

I tried to fix these problems in the spec file. Everything works except removing "*.jar" prebuilt libraries. There are 11 prebuilt libraries in the source package. Most of them can be found in the packages which are currently available in Fedora. Two of them have source available in Github which is fine as they can be contained as "Source1". 

However, there are still two prebuilt libraries ("jdmkrt.jar" and "jdmktk.jar") necessary during package builing but cannot be compiled from source."jdmkrt.jar" and "jdmktk.jar" comes from OpenDMK. They are necessary to provide SNMP support for status monitor in XtreemFS. And they can't be build from sources without sourceless "binary plug" which is non-free and unmaintained since 2007. (issue is still open on Github: https://github.com/xtreemfs/xtreemfs/issues/309)

I am afraid if I make "jdmkrt.jar" and "jdmktk.jar" be compiled during building package, it may against the Fedora Packaging Guidelines. I spent 11 hours trying to separate SNMP support from XtreemFS in order to let this package following Fedora Packaging Guidelines. Unfortunately, I am not familiar with java and I can't make it be possible.

What should I do now? I am new to packager, and I really have no idea how to break this situation or solve this problem.

If for you is not possible remove SNMP/OpenDMK support, and this make not usable this package, then close this bug. Otherwise, you can contact the "folks" in the #fedora-java or in the #fedora-bigdata IRC channel/s, to look for some volunteer to give you help.

You can not review your own package
