Changes in inplace plugin code in grails3.x are not reloading automatically

[girisagar46]

I am upgrading a project from Grails 2.5.1 to Grails 3.1.6.

My Multi-Project Build structure in Grails 3.1.6 is as follows:

- Root |--MainProject |--Pugin1ForMain |--Plugin2ForMain |--settings.gradle

I run the MainProject using grails run-app command and whenever I change my codes in Plugin1ForMain or any other plugins, the changes are not automatically recompiled like it did in Grails2.x .

Some research led me to this blog: http://mrhaki.blogspot.com/2015/11/grails-goodness-enable-hot-reloading.html and I implemented in development environment but reloading does not work.

When I create dummy projects and plugins, the reloading works fine. Reloading issue only occurs when I start moving codes from 2.5.1 to 3.1.6 project structure.

Sorry Graeme, didn't know about the ISSUE_TEMPLATE. My real issue is auto reloading of implace plugins isn't working in Grails 3.1.6 as it did in Grails2.x.

Steps to reproduce:

• clone https://github.com/girisagar46/Grails3ReloadTest
• cd to 'racetrack' folder
• change mysql password, database url (since I am using MySQL)
• Run the racetrack using run-app command
• change the code of plugin (add a controller or change the existing code in racetrackplugin)
• the project won't recompile the changes in racetrackplugin

Expected behaviour

• The changes in inplace plugin should reflect in the main application when app is still running.

Actual Behaviour

• The changes won't recompile

Environment Information

Operating System: Linux Ubuntu 14.04 Grails Version: 3.1.6 JDK Version: 1.8.60 Gradle Version: 2.12

Example Application

The steps above describe adding a new controller to the plugin. Is it the case that adding new artifacts doesn't work but editing existing artifacts does work?

[girisagar46]

@jeffbrown Adding new artifact or editing an existing one, both doesn't seem to be working.

There are a couple of problems in the attached example that prevent the reloading from working:

a) you are using an old version of Gradle which is picked up by Grails https://github.com/girisagar46/Grails3ReloadTest/blob/master/RaceTrack/gradle/wrapper/gradle-wrapper.properties#L6

b) You have hard coded the profile version to an older version (3.1.0) instead of using 3.1.6: https://github.com/girisagar46/Grails3ReloadTest/blob/master/RaceTrack/racetrack/build.gradle#L56

Both of these together prevent reloading working. When I updated the Gradle wrapper version to 2.13 and use the 3.1.6 web profile it works fine.
