Building JavaFX

This repository contains my build environment and shell scripts for building JavaFX on Linux, macOS, and Windows. The files common to all systems are found in the root bin directory, while those that are platform-dependent are found in the linux/bin, macos/bin, and win10/bin directories.

I use these files to test pull request openjdk/jfx#446, "8264449: Enable reproducible builds with SOURCE_DATE_EPOCH."

Building

I set the environment variables with the "dot" command (.) and then run the build scripts as follows:

$ . ~/bin/jfxbuild.env
$ ~/bin/develop.sh
$ ~/bin/actions.sh
$ ~/bin/release.sh
$ ~/bin/noepoch.sh

where:

• jfxbuild.env defines the SOURCE_DATE_EPOCH, JDK_HOME, and PATH environment variables for the local copy of CMake, OpenJDK, and Apache Ant.

• develop.sh creates two developer builds with targets "sdk jmods javadoc" and runs the unit tests.

• actions.sh creates two GitHub Actions builds with target "all" and runs the unit tests.

• release.sh creates two production builds with targets "sdk jmods javadoc" and runs the unit tests.

• noepoch.sh creates a production build without SOURCE_DATE_EPOCH and runs the unit tests.

Testing

After running the scripts, I test whether the build is reproducible by comparing the pair of builds created by each of the first three scripts:

$ diff -r build1 build2
$ diff -r build3 build4
$ diff -r build5 build6

The noepoch.sh script tests whether the production build still works after removing SOURCE_DATE_EPOCH from the environment.
