Not able to run the app using Gretty 4.0.3 in combination with JDK17 and Gradle 7.5.1.

[nalim1989]

I was using gretty version 3.0.3 (Jetty 9.4) together with JDK11 and Gradle 6.8. Everything worked fine.

After that, I upgraded the project to JDK17 (temurin-17.jdk) and also Gradle to 7.5.1 and gretty to 4.0.3.

I'm trying to run the app using ./gradlew jettyRun but I'm getting the following exception:

Environment config has been changed to 'local'.

I've tried with the tomcatRun too, but the same problem occurred.
Does gretty plugin support JDK17 at all?

I am using Gretty 3.0.9 with JDK 18 and 19 on Gradle 7.5.1 so yes, it does work. I'm not sure what you're hitting. @f4lco any ideas?

[nalim1989]

I've downgraded gretty according to your advice to 3.0.9. and switched from jetty11 to jetty9.4 and now everything works well with JDK17!
