HotSwap capability for SDK4 beta does not work

I’m submitting a … (check one with “x”)

[X] bug report => search github for a similar issue or PR before submitting
[ ] feature request

Expected Behavior

SDK4 with HotSwap capability should start properly according to https://github.com/Alfresco/alfresco-sdk/blob/sdk-4.0/docs/advanced-topics/hot-reloading/hotswap-agent.md#configuring-hotswapagent-in-the-project-java-11

Current Behavior

Following error can be seen (link to full log is mentioned in last section):

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
ERROR: Service 'hotswap-acs' failed to build: The command '/bin/sh -c tar -xvf $TOMCAT_DIR/trava-jdk-11-dcevm.tar.gz -C /usr/java/ &&     rm $TOMCAT_DIR/trava-jdk-11-dcevm.tar.gz &&     alternatives --install /usr/bin/java java /usr/java/dcevm-11.0.1+7/bin/java 40000 &&     alternatives --install /usr/bin/javac javac /usr/java/dcevm-11.0.1+7/bin/javac 40000 &&     alternatives --install /usr/bin/jar jar /usr/java/dcevm-11.0.1+7/bin/jar 40000 &&     alternatives --set java /usr/java/dcevm-11.0.1+7/bin/java &&     alternatives --set javac /usr/java/dcevm-11.0.1+7/bin/javac &&     alternatives --set jar /usr/java/dcevm-11.0.1+7/bin/jar &&     ln -sfn /usr/java/dcevm-11.0.1+7 /usr/java/latest &&     ln -sfn /usr/java/dcevm-11.0.1+7 /usr/java/default' returned a non-zero code: 2

Possible Solution

I tried to gunzip compressed file and adjust Dockerfile but no success

Steps to Reproduce (for bugs)

1. Generate a new AIO SDK4 project named hotswap (whole path is /opt/alfresco/sdk/hotswap)
2. $ cd /opt/alfresco/sdk/hotswap/hotswap-platform-docker/src/main/docker
3. $ wget https://github.com/TravaOpenJDK/trava-jdk-11-dcevm/releases/download/dcevm-11.0.1%2B7/java11-openjdk-dcevm-linux.tar.gz
4. $ mv java11-openjdk-dcevm-linux.tar.gz trava-jdk-11-dcevm.tar.gz # Rename TravaJDK to follow the same filename as in Dockerfile
5. Appending commands for TravaJDK and hotswap-agent.properties to Dockerfile
6. Appending command and volumes parts to /opt/alfresco/sdk/hotswap/docker/docker-compose.yml:

    command: ["catalina.sh", "run"]

and

      - ../../../hotswap-platform-jar/target/classes:/usr/local/tomcat/hotswap-agent/hotswap-platform-jar/target/classes
      - ../../../integration-tests/target/test-classes:/usr/local/tomcat/hotswap-agent/integration-tests/target/test-classes

Context

Hi Ole, The problem with gz file was fixed by adding include/exclude params to maven-resources-plugin configuration. Anyway, I am still facing some issues. I will need to do more testing on my side and then I will provide you more info. You can expect more tomorrow.

Since we just got a very large quote from JRebel folks based on annual subscription - I do not anticipate us moving to that. Any news on HotSwap from anyone?
