RPM extract jar files

I wan to create RPM packages which is used to extract only jar files:

Name:           pack-agent
Version:        1.0
Release:        1%{?dist}
Summary:        Linux Agent installation script
Group:          Utilities
License:        license
Source0:        pack-agent-1.0.tar.gz
BuildArch:      x86_64
BuildRoot:      %{_tmppath}/%{name}-%{version}-%{release}-root-%(%{__id_u} -n)
%description

%prep
%setup -q -n opt

%build

%install
#install -m 0755 -d $RPM_BUILD_ROOT/agent
#cp -ap agent/* $RPM_BUILD_ROOT/agent/

install -m 0755 -d %{buildroot}/opt
#cp -a * %{buildroot}/agent
cp -a * %{buildroot}/opt

%clean
rm -rf $RPM_BUILD_ROOT

%files
/opt
%defattr(-,root,root,-)

%doc
%changelog

It turns out that after RPM install some files are corrupted because there is a spacial way to extract files from jar file. Maybe during build simple exatract command is used I suppose.

Is there any way to solve this? I get now this error:

org.osgi.framework.BundleException: The bundle file:/opt/agent/deploy/System_Install-1.0.jar does not have a META-INF/MANIFEST.MF! Make sure, META-INF and MANIFEST.MF are the first 2 entries in your JAR!

Looks like the file is not properly extracted.

Run rpm -E '%{__os_install_post}' and find the brp-java-repack-jars script (/usr/lib/rpm/redhat/brp-java-repack-jars on my CentOS 5 system) and take a look at it.

It unpacks and repacks the jars it finds.

Newer versions might let you control it a bit but in the one I have you don't have much say over things.

For the version in CentOS 5 it looks like your choices are:

  • Define your own custom __os_install_post that doesn't call it that script
  • Update the script to be smarter about handling META-INF and MANIFEST.MF files correctly.
  • Delete that script from your system entirely
  • Remove zip and/or unzip from your system entirely

If your tarball contains jar files that should stay as they are, disable repackaging of the jar files. Add the following to the top of your spec file:

%define __jar_repack %{nil}
