Reproducible Test Case

[mkurz]

@gmethvin seems like there is a bug in your directory-watcher lib on upcoming MacOS Big Sur.

[gmethvin]

@zhye9452 @mkurz Let's report a bug on https://github.com/gmethvin/directory-watcher/issues and discuss there. In the mean time, I suppose we can switch to an alternative watch service for Play.

I suppose we can switch to an alternative watch service for Play.

While Until there's a fix out of the box, Play users can opt out of the default file watcher using the following play-plugin setting in their sbt build:

// demoes jdk7 but others are available
PlayKeys.fileWatchService := play.dev.filewatch.FileWatchService.jdk7(play.sbt.run.toLoggerProxy(sLog.value))

Maybe we should add dependency: "com.lightbend.play" %% "play-file-watch" % "x.x.x" :)

How can we add it to a lagom project

[ignasi35]

https://github.com/playframework/play-file-watch/releases/tag/1.1.13 (with BigSur support) is ready.

I think the long term plan is to completely replace play-file-watch/directory-watcher by sbt's own file watching capabilities, introduced in sbt 1, see #9956

[ennru]

Fixed with #10450

How can we add it to a lagom project

lagomFileWatchService := play.dev.filewatch.FileWatchService.jdk7(play.sbt.run.toLoggerProxy(sLog.value))

[odwrotnie]

How can we add it to a lagom project

lagomFileWatchService := play.dev.filewatch.FileWatchService.jdk7(play.sbt.run.toLoggerProxy(sLog.value))

It makes no change - I have the exception anyway.

I think then it's not active, there should be no JNA exception now.

Anyway, I don't need it anymore with Azul JDK 11.0.10, native version works fine now on M1 / BigSur.
