gretty | Advanced gradle plugin for running web | Build Tool library

I've been following along with the libGDX docs and I'm very new to Gradle and I almost know nothing about it and I ran into a problem that I couldn't fix. I tried fixing the not found problem by applying the plugin and adding classpath to it but it didn't work. Is there any way I can fix it? (Note: the problem is in html/build.gradle)

OS: Win64
IDE: Android Studio

Errors: Caused by: org.gradle.api.plugins.UnknownPluginException: Plugin with id 'org.wisepersist.gradle.plugins.get.GwtSuperDev' not found. (This is when I added the plugin) Plugin with id 'org.wisepersist.gradle.plugins.get.GwtSuperDev' not found.

I'm running a build in Azure DevOps with latest gradle (6.8) and I get NPE:

I am trying to execute a sql statement in Listener's contextInitialized method, but when I run gretty local server, it throws RuntimeException error. I can't figure out, why. It doesn't run into any errors when i comment out ps.executeQuery();.

I'm trying to run Spring MVC app using gretty plugin for Gradle (JVM version is 14) To deploy app I use tomcatRun task (tomcat version is 8.5.49).

If i use some preview feature (e.g. java.lang.String#formatted method) I have to add enable-preview flag to compileJava task:

I'm trying to work through the "Building Java Web Applications" Gradle Guide (kotlin dsl), but gradle throws an exception when building. I would really appreciate any help getting this guide to work. I'm using gradle 6.2.2. I've cloned the gradle / guides & tried building the example there with the same results.

I’m trying to upgrade some old code that used the Jetty plugin in Gradle. I would like to upgrade the Gradle version beyond Gradle v3.5, but Gradle v4.0 and above has the Jetty plugin removed. Unfortunately, we are now required to use Gretty.

I’m using IntelliJ. My problems with the newer Gretty plugin are:

• JVM Args and System properties specified on the commandline have to be manually put into the Gretty configuration.

• At least in IntelliJ, I could do out of the box debugging with the Jetty plugin, but need to run two executions including the app and the Remote, and use a different Gradle task for debugging (e.g. jettyRunDebug) with Gretty.

  What are the alternatives to Gretty? Anything that can substitute for the old Jetty plugin.

Is it possible to run Gretty projects in Docker Gradle container?

Normally the Gretty task tomcatRun starts Tomcat app server and you can browse the app at http://localhost:8080/app-name. With Docker Gradle image the task is successfully started but the container is terminated immediately after that.

Steps for reproducing the issue:

1. Install Docker.
2. Clone https://github.com/haba713/hello_gretty.
3. cd hello_gretty
4. Install Gradle wrapper: docker run --rm -u gradle -v "$PWD":/home/gradle/project -w /home/gradle/project gradle gradle wrapper
5. Run the task tomcatRun: ./gradlew tomcatRun
6. Browse http://localhost:8080/hello_gretty.
7. Terminate the task by pressing enter in terminal.
8. Run task tomcatRun with Gradle Docker image: docker run --rm -u gradle -p 8080:8080 -v "$PWD":/home/gradle/project -w /home/gradle/project gradle gradle tomcatRun
9. The task tomcatRun is started (takes some time) but for some reason the container terminates immediately after that. Maybe the task was completed without pressing any key.

I also created a Docker issue about the problem.
