Hi POI team,
We are testing the POI5.1.0 release for producing Powerpoint slideshows
and are seeing the following error being emitted when running
org.apache.poi.examples.xslf.Tutorial1 :
ERROR StatusLogger Log4j2 could not find a logging implementation.
Please add log4j-core to the classpath. Using SimpleLogger to log to the
console...
This goes away if we add log4j-core-2.14.1.jar to the classpath.
Q: Is it expected that we have to add this extra jar file to run POI or
should it be able to run quietly without?
Note: we don’t want to use any debug logs from POI.
Environment notes:
Same behaviour seen on Windows and Linux
OpenJDK version: zulu8.38.0.13-ca-fx-jdk8.0.212-win_x64
Steps to reproduce (suppose poi-bin-5.1.0-20211024.zip unpacked in
C:\poi\5.1.0) :
C:\>set
CLASSPATH=C:\poi\5.1.0\*;C:\poi\5.1.0\lib\*;C:\poi\5.1.0\ooxml-lib\*;C:\poi\5.1.0\auxiliary\*
C:\>java org.apache.poi.examples.xslf.Tutorial1
ERROR StatusLogger Log4j2 could not find a logging implementation.
Please add log4j-core to the classpath. Using SimpleLogger to log to the
console...
