gradlew clean assemble gives: No SLF4J providers were found in 0.7.2 stable

./gradlew clean assemble gives SLF4J: No SLF4J providers were found in 0.7.2 stable

It could be by system ...

openjdk 18.0.2 2022-07-19
OpenJDK Runtime Environment (build 18.0.2+0)
OpenJDK 64-Bit Server VM (build 18.0.2+0, mixed mode)

... but I do not know what to do next. Any tip?

$ ./gradlew clean assemble

Hi @bwakkie !

Likely JDK too high: openjdk 18.0.2 for the version of logger implementation. In any case, you currently need a lower version of the JDK to run Grobid, due to the dynamic libraries, see:

Great, after ... export PATH="/usr/lib/jvm/java-8-openjdk/bin/:$PATH" ... it worked! Well ... it is compiling as we speak.
