I am encountering several initialization errors with the logback.xml file
(below) that do not seem to be addressed in either this mailing list or
JIRA. I am running Logback 1.0.7 with SLF4J 1.7.2.
During initialization I receive the following Logback errors:
1. No applicable action for [outputPatternAsHeader]. Try as I might, I can
not get Logback to recognize this property.
Double-check your classpath. It might be pointing to a version of logback that's older than 1.0.3 (where <outputPatternAsHeader> was introduced). [1]
2. No applicable action for [immediateFlush]. This error may be expected, as
I was able to glean from the list and JIRA that this property has been
eliminated. Please confirm.
No, <immediateFlush> is still a valid property for layout encoders in logback-1.0.7. [2]
3. no applicable action for [withJansi] / There is no conversion class
registered for composite conversion word [highlight]. I am including
jansi-1.8.jar in the classpath but, obviously, this wouldn’t even come into
play if withJansi isn’t even recognized.
I don't have a Windows machine handy at the moment, but I'm guessing it's the same issue mentioned previously (an old version of logback in your classpath).
4. Could not find Janino library on the class path. Skipping conditional
processing. Both commons-compiler.jar and janino.jar 2.6.1 are on the
classpath. I understand that there are potential issues with the use of
conditional processing because of Janino and I’m wondering if I should
abandon this feature, though it makes the config file significantly more
elegant.
To use Janino, you must include *two* relevant jars: janino.jar and commons-compiler.jar. [3]
I just tried your logback configuration with logback-1.0.7 and Janino, and there were no config errors. It output correctly to the console (with the color codes), and it correctly wrote the pattern header to the log file at /tmp/its/Idcp.log. [4]
I wrote a HelloWorld application (output via SLF4J) with Eclipse Juno on OSX Mountain Lion. I included the following jars:
* slf4j-api-1.7.2.jar
* logback-core-1.0.7.jar
* logback-classic-1.0.7.jar
* janino-commons-compiler-2.6.1.jar
* janino-2.6.1.jar
