JBS issue: [JDK-8226754](https://bugs.openjdk.java.net/browse/JDK-8226754)
As noted in the JBS bug, the JavaFX build fails with gradle 6 (as well as not building correctly with 5.6 or later). The existing JavaFX build uses two deprecated features that are removed in gradle 6, so the build fails when building with gradle 6. Additionally, some change that went into gradle 5.6 prevents all of our resource files (e.g., css files, images, shaders) from being included in the built artifacts, which causes JavaFX to be non-functional (our unit tests catch this failure). The purpose of this bug fix is to allow JavaFX to build with gradle 6, which is needed to allow building with JDK 13. We will likely upgrade to gradle 6 in the near future. Additionally, this fixes the resource bug that was exposed (or introduced) in gradle 5.6 and also affects gradle 6. The changes are as follows: 1. Remove unneeded STABLE_PUBLISHING setting, which was transitional to allow gradle 4.x to continue working while we moved to gradle 5.x 2. Use `ivy patternLayout ...` instead of `layout "pattern", ...` 3. Specify no metadata for ivy repositories 4. Set output.resourcesDir of sourceSet to match processResources.destinationDir 5. Bump minimum gradle version to 5.3 (since it will no longer run with gradle 4.x after change 1) I verified that the build artifacts produced by gradle 5.3 before and after this changes are identical (so it is behavior neutral for the supported version of gradle). After the fix, I also verified that the build artifacts produced by gradle 5.6.2 and 6.0 nightly match those produced by 5.3. I have tested this fully on Linux and Windows, and I will do a sanity test on Mac in parallel with the review. ---------------- Commits: - bc6bd441: 8226754: FX build fails using gradle 5.6+ or 6 Changes: https://git.openjdk.java.net/jfx/pull/9/files Webrev: https://webrevs.openjdk.java.net/jfx/9/webrev.00 Issue: https://bugs.openjdk.java.net/browse/JDK-8226754 Stats: 28 lines in 4 files changed: 17 ins; 4 del; 7 mod Patch: https://git.openjdk.java.net/jfx/pull/9.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/9/head:pull/9 PR: https://git.openjdk.java.net/jfx/pull/9
