In my project I use Log4j to process all logging. The config I use:
<Appenders>
<Console name="STDOUT" target="SYSTEM_OUT">
<PatternLayout pattern="%d - %-5p %-10c - %m%n"/>
</Console>
<File name="file" fileName="logs/TAF_${sys:current_date}.log">
<PatternLayout>
<Pattern>%d{yyyy-mm-dd_HH:mm:ss.SSS} - %-5p %-10c - %m%n</Pattern>
</PatternLayout>
</File>
</Appenders>
<Loggers>
<Root level="trace">
<AppenderRef ref="file" level="DEBUG"/>
<AppenderRef ref="STDOUT" level="DEBUG"/>
</Root>
</Loggers>
The error I get:

2018-11-19 16:12:59,543 main ERROR Null object returned for File in Appenders.
2018-11-19 16:12:59,550 main ERROR Unable to locate appender "file" for logger config "root"
The first error is in dutch, which translates to: "The filename, directory name, or volume label syntax is incorrect".
This Log4J config file is used under an Ubuntu environment and works perfectly. Now I have added a Win10 machine to the pool, but I receive this error.
What am I doing wrong?
I tried to make the path absolute, "c:/Project/logs/TAF_${sys:current_date}.log", but it did not solve the problem. Every user has read/write access to the logs directory.
Other stuff I tried: Log4j logfile error FileNotFoundException
@edit: For what I can see, it looks like log4j is trying to create a file named "TAF_${sys:current_date}.log". That ofcourse doesn't work, because { and } are not valid for filenames. When the "_${sys:current_date}" is removed, I am able to create the log file. How am I able to use the expression again, to add the current date/time?
@edit2:Found the answer here. I needed to set the system property "current_date" in the code.
