I'm building a Spring Boot project making use of S/4HANA custom OData Service and Java VDM. I have been following various tutorials on SAP Blog, developer.sap.com or S4H13 course - the approach is pretty much the same. I managed to successfully generate VDM for my Custom OData Service based on the edmx file, created all necessary commands, methods in the controller and so on.
Unfortunately, I'm encountering an issue when launching the project locally.
I use the following command first:
mvn clean package and later, when I'm in the application directory want to run the project:
The project build fails with the following errors and exceptions:
2020-07-31 12:45:20.941 ERROR 70176 --- [main] o.a.c.c.C.[Tomcat].[localhost].[/] : Exception sending context initialized event to listener instance of class [com.sap.cloud.sdk.s4hana.connectivity.ErpDestination]

Please find the outdated dependency in your dependency tree:
I need to be able to log an Exception as a single record in my logs, which will make it much easier to investigate issues in Kibana / Elasticsearch. From what I can tell from the documentation for slf4j, the Logger interface requires messages to be
Strings. Is my only option to remove newline characters from the Exception message before passing it to the Logger?
For context, I am using the following:

I'm trying to set up sending my application logs to Google Cloud Logging, but no matter what I try, the logs are not visible in the Log Viewer.
- using the Java Logging Logback appender directly, following all of the steps in the documentation, setting different combinations of parameters
- using Spring Cloud GCP, again following all of the tutorials and trying different configurations
- using the CLI to write log entries, using the examples from the docs
- using the API explorer to write log entries, providing all of the required fields
The Log ingestion tab shows that the data is actually ingested and I am able to retrieve the entries using
gcloud logging read or using the API explorer.
Unfortunately, the logs are not showing up in the viewer, which greets me with
[..] You do not have any logs in your project right now.
The logging API is, of course, enabled (I guess I wouldn't be able to get the CLI/API explorer to work without it).
Any clues what's wrong? Can it be that my logging entries have invalid format or are missing some key bit of information?

I think I tried everything by now and I believe there's just something wrong with that particular project.
I followed through on the walkaround that I edited into the question and created a completely new project. I ran a lambda function which logged a line to make sure both classical and preview modes of the viewer are working. Finally, I moved all of my resources to the new project.

I am using a lambda function and writing it in Java. I was looking up logging for Lambda functions when I read the docs and they support log4j - http://docs.aws.amazon.com/lambda/latest/dg/java-logging.html#java-wt-logging-using-log4j.
I was wondering if we could use logging using the Slf4j annotation as well since Slf4j is only a binding annotation. Has anybody tried using Slf4j before with lambda?...
ANSWERAnswered 2020-Feb-18 at 16:59
Yes, you can. Just add the following dependencies to your project:
I've tried to search on Spring documentation + articles on the internet + questions from Stackoverflow but I didn't find any information about it. For me the configuration of Log4J2 (especially the pattern) is much simpler, personal taste.
Also, I find that Log4J2 has better performance than Logback according to these articles:
And if we are to consider Async Logger, the performance is expediently higher in favor of Log4J2 according to Apache - https://logging.apache.org/log4j/2.x/performance.html and yes I know that it's their job to make their framework look better but I do believe that they are reliable.
My assumption is that Pivotal choose Logback to be the default because Log4J2 came sometime after they released version 1.0 of Spring-Boot.
Can anyone shed some light on this? Is my assumption correct?...
ANSWERAnswered 2019-Jul-07 at 16:35
This is the reason:
Phil Webb: I don't really feel like the arguments being made justify the introduction of a breaking change. [...] If we were starting Spring Boot today we may well have chosen Log4J2 over Logback, but I think so far there are no massively compelling reasons to cause our users upgrade pain. [...] I think it's unlikely that we'll consider switching the default logging system until the next major release of Spring Boot.
Ralph Goers: support for configuring Log4j 2 from Spring Cloud Config is planned to be added.
I am trying to write a java based lambda function. Everything works fine except the logging. I have the log4j2.xml file in classpath.
I have also followed the instruction laid down in AWS Lambda LOgging in Java to the word.
I get this in the log when I trigger the Lambda function.
log4j:WARN No appenders could be found for logger (com.amazonaws.AmazonWebServiceClient). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
I use maven to package the jar. The pom.xml has the following dependencies....
ANSWERAnswered 2018-Mar-01 at 13:36
That error message is produced by an old version of Log4j (1.2.x) that’s on the classpath somehow. Log4j 2.x error messages look different.
Please remove the Log4j 1.2.x jar from the classpath. If any of the libraries have a dependency on Log4j 1.2, add the adapter
No vulnerabilities reported
You'll need to obtain the google-cloud-logging library. See the Quickstart section to add google-cloud-logging as a dependency in your code.
