Since you're packaging things that are already "built", then yes there's
nothing to build. You still want to treat the jars and such as
sources to be able to create a src.rpm of the thing and to avoid
hardcoding paths to your own setup etc.
So you'd have something like
SOURCE0: myapp-1.jar
SOURCE1: myapp-2.jar
SOURCE2: myapp.sh

Putting things into users' home directory is not going to work well and
goes against the ideas of rpm. Install the app into a system-wide
location, such as %{_libdir}/myapp for the jars and other misc bits and
%{_bindir}/myapp for the launcher script.
Assuming the example SOURCE's from above, you'd have something like:
%install
mkdir -p $RPM_BUILD_ROOT%{_bindir} $RPM_BUILD_ROOT%{_libdir}
install -m 644 %{SOURCE0} %{SOURCE1} $RPM_BUILD_ROOT%{_libdir}/
install -m 755 %{SOURCE2} $RPM_BUILD_ROOT%{_bindir}/
For this to work you'll need to set BuildRoot in your spec (you'll always
want to have it anyway), something like this'll do:
BuildRoot: %{_tmppath}/%{name}-%{version}

%install is used to put the results to a directory tree (again, you'll
want the buildroot in your spec)

While defining name, version etc this way isn't "wrong", it's unnecessary
and redundant, see below.

Never blindly copy what's in build or sources directories, you don't know
what other packages have their sources and builds in there (eg on my
system, this is gigabytes of stuff)

Try something like this:
---
Name: PCMonitor
Release:?? 1
License:?? GPL
Summary:?? PC Monitor
Group:???? Development/Languages
Source0: pcmonitor.jar
Source1: pcmonitor-util.jar
Source2: pcmonitor.sh
BuildArch: noarch
BuildRoot: %{_tmppath}/%{name}-%{version}
%description
PC Monitor
%install
rm -rf $RPM_BUILD_ROOT
mkdir -p $RPM_BUILD_ROOT/%{_bindir}
mkdir -p $RPM_BUILD_ROOT/%{_libdir}/pcmonitor
install -m 644 %{SOURCE0} %{SOURCE1} $RPM_BUILD_ROOT%{_libdir}/pcmonitor
install -m 755 %{SOURCE2} $RPM_BUILD_ROOT%{_bindir}/
%clean
rm -rf $RPM_BUILD_ROOT
%files
%{_bindir}/pcmonitor.sh
%{_libdir}/pcmonitor

I don't know the names of your jar files and scripts so you'll need to
adjust them, and probably you need to adjust the launcher script to take
into account that the location of jar's which is not your home directory
anymore etc.
