hot deployment with gradle [message #1839150]

Hi,
i have created a DSL web application. I run this application in the command prompt by executing the command "gradlew jettyRun". The problem is that each time i make some minor changes to my code, i have to stop the gradle for saving then. After that i have to start again the jetty. Because it is very time consumable and boring process, is there any way to automate this some-how?

thanks in advance,
Michael

what happens when you start the serverlauncher main class in the .web project in debug mode from eclipse instead?

Hi Christian,

i am using vs code because the only files that i modify, are under the web app folder. Also when running the gradle form the embedded terminal of vscode, i get the same behavior as mentioned in my previous post.

Then maybe you have to modify the jetty run script to start in debug mode to see if this will trigger hot code replacement

in the build.gradle file of my web project i run the jetty as follows :

task jettyRun(type:JavaExec) {
	dependsOn(sourceSets.main.runtimeClasspath)
	classpath = sourceSets.main.runtimeClasspath.filter{it.exists()}
	main = 'eu.test.web.ServerLauncher'
	standardInput = System.in
	group = 'run'
	description = 'Starts an example Jetty server with your language'
}

searching in google i found this url --> https://stackoverflow.com/questions/32329282/hot-code-deployment-in-jetty

what information should i add inside the jettyRun task?
I am a little bit lost.

The problem is i have no idea which and how you compile the Java code in
Vscode.

If you use Java extension or gradle in continous Mode
I assume that new class files will be produced

Then if you configure the jetty run task to run in debug mode (i assume the docs on Java task will have some hints on that https://docs.gradle.org/current/dsl/org.gradle.api.tasks.JavaExec.html)
Or you use the Java extension to start the server launcher class in debug mode that then
It should work
