The appender.setLayout(patternLayout); call generates a warning. However, at that time the appender does not know its context. Change appender.setLayout(patternLayout); appender.setContext(lc); to appender.setContext(lc); appender.setLayout(patternLayout); In which case you will get the warning message: |-WARN - This appender no longer admits a layout as a sub-component, set an encoder instead. |-WARN - To ensure compatibility, wrapping your layout in LayoutWrappingEncoder. |-WARN - See also http://logback.qos.ch/codes.html#layoutInsteadOfEncoder for details Visit http://logback.qos.ch/codes.html#layoutInsteadOfEncoder for further instructions.

Hi,

I’m using logback 0.9.28 and I’m trying to configure logback programmatically with the following code:

public void prepare() {

LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();

lc.reset();

lc.getLogger("com").setLevel(Level.DEBUG);

lc.getLogger("com.example").setLevel(Level.DEBUG);

lc.getLogger("com.example.test").setLevel(Level.DEBUG);

lc.getLogger("com.example.test.inner").setLevel(Level.DEBUG);

PatternLayout patternLayout = new PatternLayout();

patternLayout.setContext(lc);

patternLayout.setPattern("%-5level %logger - %msg%n");

patternLayout.start();

ConsoleAppender<ILoggingEvent> appender = new ConsoleAppender<ILoggingEvent>();

appender.setLayout(patternLayout);

appender.setContext(lc);

appender.start();

lc.getLogger("root").addAppender(appender);

lc.start();

StatusPrinter.printInCaseOfErrorsOrWarnings(lc);

super.prepare(testCase);

}

I keep getting the following message: LOGBACK: No context given for ch.qos.logback.core.ConsoleAppender[null].

I’m seeing the log messages in the console, but I fail to understand why I’m getting this message.

Thanks,

Shahar
