This PR modifies the header and footer of the javadoc-generated API docs to add "DRAFT $VER-ea+$BLD" to clearly identify an ea build of the docs, and also to make it clear which build number the docs refer to. This matches was the JDK does. For GA builds, there will be no change to what we generate today. Since I had to add logic to filter the javadoc properties defined in `build.javadoc` to add the DRAFT message if not a GA build, I also changed the properties to not hard-code the major version of JavaFX, thus reducing the duplication.
I ran three builds to test this, an ordinary developer build, an EA build, and a GA build as follows: #### Developer build Command line: gradle javadoc Generated docs: https://cr.openjdk.org/~kcr/8340829/javadoc-internal/ #### EA build Command line: gradle -PPROMOTED_BUILD_NUMBER=98 -PHUDSON_BUILD_NUMBER=1234 -PHUDSON_JOB_NAME=jfx-dev javadoc Generated docs: https://cr.openjdk.org/~kcr/8340829/javadoc-ea/ #### GA build Command line: gradle -PMILESTONE_FCS=true -PPROMOTED_BUILD_NUMBER=99 -PHUDSON_BUILD_NUMBER=4321 -PHUDSON_JOB_NAME=jfx-dev javadoc Generated docs: https://cr.openjdk.org/~kcr/8340829/javadoc-fcs/ ------------- Commit messages: - 8340829: Generated API docs should clearly identify EA builds Changes: https://git.openjdk.org/jfx/pull/1583/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=1583&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8340829 Stats: 19 lines in 3 files changed: 11 ins; 2 del; 6 mod Patch: https://git.openjdk.org/jfx/pull/1583.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/1583/head:pull/1583 PR: https://git.openjdk.org/jfx/pull/1583
