如何在我的 build.gradle 文件中找到要实现的 JavaFX 的最新版本？

Question

What I believe is the official website, openjfx.io , tells me to use version 0.0.10 in gradle. However, It's incompatible with JDK 8 and 17, spitting out java.lang.UnsupportedClassVersionError: org/openjfx/gradle/JavaFXPlugin has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0 I looked through the JavaFX repo, but couldnt find a good version number to replace 0.0.10 with, but I don't think 0.0.10 is really the most recent one. Where can I find the most recent build number?

Answer 1

I don't know where you got 0.0.10, that is not correct.

See the Products Roadmap at GluonHQ.com. You will see that 17.0.1 is currently the latest, with 18 in early-access.

The JavaFX (OpenJFX) releases have been synced to arrive at about the same time as the Java releases, and use the same major version number. A convenient approach.

But OpenJFX releases do not require the latest Java. The Release Notes for 17 says it requires Java 11 or later.

I suggest you generally do your development work with the latest Java and the latest JavaFX while aiming your deployments at the latest Long-Term Support (LTS) version of both. Note that Oracle recently announced a change in the LTS cadence from every three years to every two years. Presumably JavaFX will follow that as well.
