Scala junit picking up wrong log4j.properties file - scala

Question

I have a test written in Scala, using junit. The test is in a module of a multi-pom with many other modules.
Here is the code of the test:
import org.apache.log4j.Logger
import org.apache.logging.log4j.scala.Logging
import org.junit._
class MyTest extends Logging {
#Test
def mainTest() = {
//val logger = Logger.getLogger("MyTest")
logger.fatal("fatal")
logger.error("error")
logger.warn("warn")
logger.info("info")
logger.debug("debug")
logger.trace("trace")
}
}
And here is the log4j.properties file, which is in the resources folder:
log4j.rootCategory=ALL, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.target=System.out
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{1}: %m%n
The maven dependencies are:
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api-scala_2.10</artifactId>
<version>2.8.2</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.8.2</version>
</dependency>
When I run the test, the debug and trace levels are not printed.
It seems to me that the logger might be picking up a files from one of the other projects. why?
If I uncomment the first line of the test, all the levels get printed.
Tried adding -Dlog4j.debug to the run command, but log4j seems to be ignoring it.
Any idea what I'm missing?

You are using log4j2.
Your file name should be log4j2.properties.
Also, the syntax of the .properties file has changes. The following example, taken from here, will get you started:
name=PropertiesConfig
property.filename = logs
appenders = console, file
appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
appender.file.type = File
appender.file.name = LOGFILE
appender.file.fileName=${filename}/propertieslogs.log
appender.file.layout.type=PatternLayout
appender.file.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
loggers=file
logger.file.name=guru.springframework.blog.log4j2properties
logger.file.level = debug
logger.file.appenderRefs = file
logger.file.appenderRef.file.ref = LOGFILE
rootLogger.level = debug
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = STDOUT
