Add option to runner for enabling DEBUG Mode

[TobiasNx]

At the moment you only can set JAVA embedded MF Workflows to debug mode. But it would be great to enable the debug mode for the CLI Version too. Thinking about adding an option debug=trueor something like this.

You mean for logging?

Changing INFO to DEBUG, like you would do here:
https://gitlab.com/oersi/oersi-etl/-/blob/68a658e994bcc5d870d9420560fcb517b8cc13c8/src/main/resources/log4j.properties#L7-10

Right, that should basically work the same way for the runner, in that case in config/log4j.xml. Not sure if it works though, I thought we had an issue for that (here or in the metafacture-fix repo), but I didn't find it now.

Since I test a lot of things via the command line with the Metafix Runner, this option would still be great.

Could this help? https://medium.com/@kasunbg/change-log4j2-default-logging-level-to-info-b25db8723eb9

Something like: Adding: -Dorg.apache.logging.log4j.level=DEBUG

Also metafacture-runner/src/main/dist/config/java-options.conf exists. It seems that the core included runner can adjust this. BUT the metafix runner cannot do this.

Let's do separation of concern : Fix is Fix and Core is Core.

You can use the debug logging using the CLI as follows:

#change the log level from "info" to "debug":
sed -i 's#info#debug#g' metafacture-runner/src/main/dist/config/log4j.xml 
# generate the distribution:
$ ./gradlew distZip; 
# change to the location to the flux.sh (assuming you have generated the distribution on "master" branch):
$ cd metafacture-runner/build/distributions/metafacture-core-master-SNAPSHOT-dist
$ bash  flux.sh $pathTo/your.flux

Note that you have to insert | log-stream into "$your.flux" after your morph or fix command. Output looks like:

DEBUG [main] [StreamLogger] start record 1
DEBUG [main] [StreamLogger] start entity author[]
DEBUG [main] [StreamLogger] start entity 1
DEBUG [main] [StreamLogger] literal @type=Person
DEBUG [main] [StreamLogger] literal name=Katja Königstein-Lüdersdorff
