Hi,
I have downloaded the Calcite and opened its Gradle project in IntelliJ
IDEA 2019.3.2. I had a problem that it could not load the slf4j classes
correctly (I was getting the SLF4J: Failed to load class
"org.slf4j.impl.StaticLoggerBinder" error). Finally, I resolved the
problem by adding the following lines into build.gradle.kts of the :core
module:
------------------------------
/dependencies /*{*
* ... *
/implementation/(*"org.slf4j:slf4j-api:1.7.3"*)
/implementation/(*"org.slf4j:slf4j-simple:1.7.3"*)
...
}
------------------------------
Now get rid of the error; however, the logger is always set to INFO
logging level regardless of the core\src\test\resource\log4j.properties.
Currently, my log4j.properties looks as follows:
------------------------------
/# Change rootLogger level to WARN/
*log4j.rootLogger*=*ALL, A1*
/# A1 goes to the console/
*log4j.appender.A1*=*org.apache.log4j.ConsoleAppender*
*log4j.appender.A1.layout*=*org.apache.log4j.PatternLayout*
*log4j.appender.A1.layout.ConversionPattern*=*%d [%t] %-5p - %m%n*
------------------------------
I run the CsvExample tests without any logging. When I debug, I see that
the RelOptRuleCall.LOGGER is set to INFO logging level. The
RelOptRuleCall.LOGGER is an instance of org.slf4j.impl.SimpleLogger. I
was also following the
<https://calcite.apache.org/docs/howto.html#tracing> instructions but
without luck (the RelOptRuleCall.LOGGER is set to INFO despite any
log4j.properties changes).
I'm using IntelliJ IDEA 2019.3.2 Community edition and Windows 10. I was
also trying JDK 1.8 instead of default JDK 11 but with the same result.
What am I doing wrong? Thanks, Radim
