Updated Groovy resetAgent: https://github.com/JetBrains/intellij-community/blob/master/plugins/groovy/hotswap/agentSrc/org/groovy/debug/hotswap/ResetAgent.java

git clone --single-branch -b 7.0.0-SNAPSHOT https://github.com/codeconsole/website.git website7 && cd website7 && ./gradlew bootRun

if you want to try Hot Swap Agent then hit CTRL-C and run the following

sdk install java 21.0.4-jbr
mkdir ~/.sdkman/candidates/java/21.0.4-jbr/lib/hotswap/
cp lib/hotswap-agent-2.0.1.jar ~/.sdkman/candidates/java/21.0.4-jbr/lib/hotswap/hotswap-agent.jar
./grailsw
grails> run-app

1 line command to getting hot swap working without having to do anything

git clone --single-branch -b 7.0.0-SNAPSHOT https://github.com/codeconsole/website.git website7 && cd website7 && sdk env install && ./hotswapSetup.sh && ./grailsw

Let's explore getting hotswap agent to work on grails-forge generated apps without any user action. This may utilize Gradle toolchains with https://plugins.gradle.org/plugin/org.gradle.toolchains.foojay-resolver-convention plus a gradle plugin to place the required jars in the right locations.
