grunt watch doesn't work #68

Open keithkml opened 9 years ago

keithkml commented 9 years ago

I'm trying to run mvn grunt:grunt -Dtarget=watch. It hangs at "waiting..." forever, even after I change source files.

$ mvn grunt:grunt -Dtarget=watch

keithkml commented 9 years ago

PS: I don't have a grunt-maven.json file - am I supposed to?

adamdubiel commented 9 years ago

You should have grunt-maven.json file generated automatically in your target-grunt. Just check if it's there. Then - do you load gruntMavenProperties in Gruntfile? (https://github.com/allegro/grunt-maven-npm#watch)

keithkml commented 9 years ago

Yes, you can see in the original post that I do indeed include gruntMavenProperties.

keithkml commented 9 years ago

here's target-grunt/grunt-maven.json

{
    "filesToWatch": "/Users/keith/Code/wham/server-new-website/src/main/webapp/homepage/**",
    "directoryToWatch": "/Users/keith/Code/wham/server-new-website/src/main/webapp/homepage",

}
adamdubiel commented 9 years ago

Sorry, i missed that part :) Could you run this via vanilla Grunt from target-grunt with debug flag to see what watch task thinks it watches?

keithkml commented 9 years ago

Not sure I see a watch path...

grunt -v watch this will show you all paths

keithkml commented 9 years ago

Seems to me that the issue is that it's looking in target-grunt for changes, not in my original source dir.

Hm, thats weird - see sandbox project - the output there shows:

Watching ../src/main/webapp/static for changes.
Watching ../src/main/webapp/static/bin for changes.
Watching ../src/main/webapp/static/test for changes.
Watching ../src/main/webapp/static/Gruntfile.js for changes.

Notice that it first goes up one ../src/... to watch files in src. Can you check if sandbox works for you?

keithkml commented 9 years ago

Yep, sandbox works great. What do you think the difference might be?

adamdubiel commented 9 years ago

I dont see much of a differemce, can you enter path for files to be watchhed manually and see if it catches the right files? Lets debug it step by step, first we rule out grun-maven.json fault.

keithkml commented 9 years ago

Sure, enter those paths where?

adamdubiel commented 9 years ago

Just enter path from filesToWatch property from grunt-maven.json to watch task files in gruntfile (instead of template).

adamdubiel commented 9 years ago

What i mean is to use:

watch: {
      maven: {
        files: ['/Users/keith/Code/wham/server-new-website/src/main/webapp/homepage/**'],
        tasks: 'default'
      }
    }

I couldn't write it while replying via mobile :)
