%description
In a nutshell, Java Packages Bootstrap (JPB) is a standalone build of all Java
software packages that are required for Java Packages Tools (JPT) to work.

In order to achieve reliable and reproducible builds of Java packages while
meeting Fedora policy that requires everything to be built from source, without
using prebuilt binary artifacts, it is necessary to build the packages in a
well-defined, acyclic order. Dependency cycles between packages are the biggest
obstacle to achieving this goal and JPT is the biggest offender -- it requires
more than a hundred of Java packages, all of which in turn build-require JPT.

JPB comes with a solution to this problem -- it builds everything that JPT needs
to work, without reliance on any Java software other than OpenJDK. JPT can
depend on JPB for everything, without depending on any other Java packages. For
example, JPB contains embedded version of XMvn, removing dependency of JPT on
XMvn, allowing JPT to be used before one builds XMvn package.
