Maven

Apache Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project’s build, reporting and documentation from a central piece of information.

Maven is by far the most consistent Java build system, allowing large amount of automation. In most common situations only following steps are necessary:

  1. In %build section of the spec file use %mvn_build macro

  2. In %install section, use %mvn_install macro

  3. Use generated file .mfiles lists to populate %files section with -f switch

Common spec file sections
BuildRequires:  maven-local
...
%build
%mvn_build
...

%install
%mvn_install
...


%files -f .mfiles
%dir %{_javadir}/%{name}

%files javadoc -f .mfiles-javadoc

The macros %mvn_build and %mvn_install automatically handle building of the JAR files and their subsequent installation to the correct directory. The corresponding POM and metadata files are also installed.
