SDK4 Integration Tests extending AbstractAlfrescoIT won't stop at breakpoints?

[phivuu-2]

I have used the ./run.sh script to spin up an instance of ACS with docker. I want to step through the code using the IDE Intellij. This works with the HelloWorldWebScriptIT which doesn't extend any classes. However, DemoComponentIT and CustomContentModelIT which extend AbstractAlfrescoIT seem to pass the tests without stopping at the breakpoints. Am I missing any configuration?

Can you cross check the DockerFile in your platform-docker Artifact. See if hotswap-agent.properties is being copied to the containers. 

"COPY hotswap-agent.properties $TOMCAT_DIR/webapps/share/WEB-INF/classes"

if you can't see above instruction in the DockerFile, then add it and try again.

I currently do not have it in DockerFile. I would like the capabilities of hotswapagent and tried to follow the guide https://github.com/Alfresco/alfresco-sdk/blob/master/docs/advanced-topics/hot-reloading/hotswap-agen...

Configuring HotSwapAgent in the project (Java 8)

However, I got stuck at step 2 on this command: 

cp linux_amd64_compiler2/product/libjvm.so /usr/java/default/jre/lib/amd64/server

cp: cannot create regular file ‘/usr/java/default/jre/lib/amd64/server’: No such file or directory

DockerFile contains:

# Hot reload - Hotswap agent
COPY hotswap-agent.properties $TOMCAT_DIR/webapps/alfresco/WEB-INF/classes

# Download and Install the more capable DCEVM, which will allow more changes to classes, such as new methods
RUN mkdir -p dcevm \
    && curl -L -o dcevm/DCEVM-8u181-installer.jar "https://github.com/dcevm/dcevm/releases/download/light-jdk8u181%2B2/DCEVM-8u181-installer-build2.jar" \
    && cd dcevm \
    && jar -xvf DCEVM-8u181-installer.jar \
    && cp linux_amd64_compiler2/product/libjvm.so /usr/java/default/jre/lib/amd64/server

# Download HotSwap Agent - it is used in the Docker Compose file.
RUN cd /usr/local/tomcat \
    && mkdir -p hotswap-agent \
    && curl -L -o lib/hotswap-agent-1.3.0.jar "https://github.com/HotswapProjects/HotswapAgent/releases/download/RELEASE-1.3.0/hotswap-agent-1.3.0.jar"

docker-compose.yml contains:

alfresco-trap-acs:

  build:
    dockerfile: ./Dockerfile
    context: ../../../alfresco-trap-platform-docker/target

If you have generated your project structure using SDK4, then all the required DockerFiles would already be available.

All you need to do is, to add the below given line in your platform-docker project's DockerFile:

COPY hotswap-agent.properties $TOMCAT_DIR/webapps/alfresco/WEB-INF/classes

After you made the changes and restarted the containers, you need to start remote debug. You should be able to put breakpoints.

For remote debugging follow the instructions given here: 

Intellij: https://github.com/Alfresco/alfresco-sdk/blob/master/docs/advanced-topics/debugging/debug-...

Eclipse: https://github.com/Alfresco/alfresco-sdk/blob/master/docs/advanced-topics/debugging/debug-eclipse.md

See this post, it was similar to your case: https://hub.alfresco.com/t5/alfresco-content-services-forum/sdk-4-hotswap-agent-not-working/m-p/1107...
