The same requirement applies to next/* (described below), which will
become a go1.XX.txt for XX >= 19.

The next/ directory contains the only files intended to be mutated.
Each file in that directory contains a list of features that may be added
to the next release of Go. The files in this directory only affect the
warning output from the go api tool. Each file should be named
nnnnn.txt, after the issue number for the accepted proposal.

The build process state also includes state that is tied to a particular Gradle user home directory.
When that directory changes between Gradle invocations, the state is discarded and recreated.
Typically, the Gradle user home directory does not change for a given process, so this is effectively process state.
