`~run` not working as expected with sbt 1.3.x

Open malliina opened this issue 5 years ago • 11 comments

Play Version

Play 2.8.0 with sbt 1.3.4

API

Scala

Operating System

Windows 10 Pro

JDK

openjdk version "11.0.5" 2019-10-15 OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.5+10) OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.5+10, mixed mode)

Expected Behavior

  1. git clone [email protected]:playframework/play-samples.git
  2. cd play-samples/play-scala-hello-world-tutorial/
  3. sbt
  4. ~run
  5. Make a change to source code
  6. Recompilation is triggered when files are changed

Actual Behavior

Recompilation is not triggered.

Refreshing the browser window (= making a request to the app) does trigger recompilation, but AFAIK this should happen already when files change.

Downgrading to sbt 1.2.8 makes triggered execution work again as expected. Triggered execution for the compile task works using any version of sbt I have tried, so this issue is only about the run command with sbt 1.3.x (on Windows).

I have tried different fileWatchService implementations but the issue persists.

Hi @malliina,

Is this happening exclusively for ~run or any command using triggered execution? For example, if you run ~test, does it re-executes the tests on file changes?

Best.

Hi @marcospereira,

This is happening exclusively for ~run. Others like ~test and ~compile re-execute on file changes as expected.

malliina avatar Jan 10 '20 06:01 malliina

I can confirm this is happening in macOS as well. Thanks for reporting, @malliina.

When running with sbt --debug ~run, I can see the following after changing a file:

So, it looks like sbt is correctly detecting the file changes, but Play ~run is failing to react to that.

@malliina could you please run with --debug as I did above and confirm if you are observing something similar?

marcospereira avatar Jan 10 '20 22:01 marcospereira

@marcospereira I ran sbt --debug ~run and it appears I have similar behavior:

Here are some observations.

~compile

[play-scala-hello-world-tutorial] $ ~compile
[warn] There may be incompatibilities among your library dependencies; run 'evicted' to see detailed eviction warnings.

When I type ~compile, I see that

  1. first sbt compiles 10 Scala sources (executing compile) then
  2. the watcher logs "Monitoring source files for root/compile".

~run

[play-scala-hello-world-tutorial] $ ~run

--- (Running the application, auto-reloading is enabled) ---

[info] p.c.s.AkkaHttpServer - Listening for HTTP on /0:0:0:0:0:0:0:0:9000

(Server started, use Enter to stop and go back to the console...)

Similarly, run first gets executed. This would start the dev mode, but watcher hasn't started.

Now if I enter Ctrl-D, it then goes into watching...

This is still not working with sbt 1.4.6... I guess this is to be fixed in Play somewhere... sometime...

mkurz avatar Jan 28 '21 09:01 mkurz

I did some research. The behaviour in following code block differs in sbt 1.2 and sbt 1.3: https://github.com/playframework/playframework/blob/96a5c50b1cb7802819213fb13a5e2bfa513ac9aa/dev-mode/sbt-plugin/src/main/scala/play/sbt/run/PlayRun.scala#L145-L149

In sbt 1.2 watched.watchSources(state) will always return the sources that are being watched and the iterator and collect "runs", in sbt 1.3 however watched.watchSources(state) will never return anything... (FYI: sourcesFinder will be called every couple of ms to find if source have been changed, so basically in sbt 1.3 it results in a no-op)

According to the 1.3 release notes things changed for file watching... Also this issue here seems related: https://github.com/sbt/sbt/issues/5561 So there were some changes that needs config adjustments.

@eatkins @eed3si9n Given my research, do you know how to fix that or how to configure stuff?

One more thing: It seems there is another behaviour change in sbt 1.4: https://github.com/playframework/playframework/blob/96a5c50b1cb7802819213fb13a5e2bfa513ac9aa/dev-mode/sbt-plugin/src/main/scala/play/sbt/run/PlayRun.scala#L112-L121 Until sbt 1.3 when calling ~run, the first Some(watched) case would always be entered, but starting with sbt 1.4 the None case will be entered (which I think is not intended by this code here...) So another thing that needs attention.

Any news how to get ~run to run?

This is exactly my problem: https://github.com/playframework/playframework/issues/9983#issuecomment-574801920

I removed references to ~run in the docs until we fixed it:

  • #12734
  • #12735
  • #12736

Opened a placeholder PR with the docs re-introduced:
