Hi all,

I am trying to configure Log4J for Xtext however I couldn't get it working.
Obviously I did something wrong so below you can find the steps that I took.

I created a fragment project in eclipse with the following Manifest:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: org.my.company.log4j.config
Bundle-SymbolicName: org.my.company.log4j.config
Bundle-Version: 1.0.0.qualifier
Fragment-Host: org.apache.log4j;bundle-version="1.2.15.v201012070815"
Bundle-RequiredExecutionEnvironment: JavaSE-1.6

In the source folder I have the following log4j.properties file:

log4j.rootCategory=INFO, S

log4j.logger.org.eclipse.xtext=DEBUG

log4j.appender.S = org.apache.log4j.ConsoleAppender
log4j.appender.S.layout = org.apache.log4j.PatternLayout
log4j.appender.S.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss} %c{1} [%p] %m%n

I exported the project as a deployable fragment and added the resulting jar file to the classpath of my project. However I do not get any messages in the console.

What is the right way to configure log4J?

Thanks in advance.

Goran,

did you remove org.eclipse.xtext.logging from your launch configuration?

Regards,
Sebastian

Hi Sebastian/Goran, I am stuck with same problem. Below are the steps I followed:
1:Created a logging fragment "X"as above and download the fragment plugin by installing a new software option .
2:Now I have a project "Z" to run which uses another custom plugin "Y" which we have built. The custom plugin"Y" has log4j statements.
I would like to see the log statements present in Y when we run the project "Z" on console. Please help....

Hi

Thank you for activating this old thread. A "log4j:WARN Please initialize the log4j system properly." in my Tycho Surefire tests has been bugging me for some time.

It looks as if some of the information such as https://kthoms.wordpress.com/2010/08/18/building-xtext-projects-with-maven-tycho/ is now out of date. It appears to recommend ch.qos.logback.classic that is not available on my installation.

I found that the https://wiki.eclipse.org/Tycho/FAQ#How_do_I_install_the_org.eclipse.osgi.compatibility.state_fragment.3F approach works.

Just add:

<requirement>
<type>eclipse-plugin</type>
<id>org.eclipse.xtext.logging</id>
<versionRange>[1.0.0,2.0.0)</versionRange>
</requirement>

to get the elusive fragment installed.

Regards

Ed Willink
