cache-stack and Google_Ping2

[Jussi Jokela]

Hi,

We are having some problems with --cache-stack=google and Google_Ping2 (https://github.com/jgroups-extras/jgroups-google). We are running Keycloak version 20.0.1 in GCP,  and when trying to deploy the container it fails with the following errors:

ERROR: Error starting component org.infinispan.remoting.transport.Transport
ERROR: Lcom/google/cloud/storage/Storage;

ERROR: com.google.cloud.storage.Storage

Here are the steps we have done so far:

1. Copy jgroups-google-1.0.0.Final.jar to /opt/keycloak/providers/

2. Build Keycloak with --cache-stack=google

3. Start Keycloak with -Djgroups.google.bucket_name=bucket-name

We have tried different versions, copying jgroups-core and google-cloud-storage jars etc. but nothing seems to work. What are we missing? Any ideas?

I am having the same problem.  Did you ever resolve this?

Any update on this issue. I am facing same issues.

Along with the error mentioned by author, I also see the one as below:

Caused by: java.lang.ClassNotFoundException: com.google.cloud.storage.Storage
at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:641)
at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:188)
at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:525)

My speculation is that the provided jar file somehow is not being registered which is why the dependent class is getting resolved.

Any inputs are highly appreciated.

Thanks.

Finally, I was able to make it work.

I had to add the dependencies one-by-one based on the errors received in the logs. It was an exhaustive exercise but successful at the end. Below are the jar files that I had to put in providers folder along with the jgroups-google-1.0.0.Final.jar
