DefaultLog

public DefaultLog(org.slf4j.Logger logger)

Method Details

isTraceEnabled

public boolean isTraceEnabled()

Description copied from interface: Log

Returns true if the trace error level is enabled.

The default implementation returns false for backward compatibility with existing Log implementations.

Specified by:

isTraceEnabled in interface Log

Returns:

true if the trace error level is enabled

trace

public void trace(CharSequence content)

Description copied from interface: Log

Sends a message to the user in the trace error level.

Trace is the most verbose level, intended for Maven core internals such as resolver negotiation, model interpolation, and lifecycle ordering details. Use Log.debug(CharSequence) instead for messages that help users investigate their build (e.g. why a module was recompiled).

The default implementation is a no-op for backward compatibility.

Specified by:

trace in interface Log

Parameters:

content - the message to log

trace

public void trace(CharSequence content,
 Throwable error)

Description copied from interface: Log

Sends a message (and accompanying exception) to the user at the trace error level. The error's stacktrace will be output when this error level is enabled.

The default implementation is a no-op for backward compatibility.

Specified by:

trace in interface Log

Parameters:

content - the message to log

error - the error that caused this log

trace

public void trace(Throwable error)

Description copied from interface: Log

Sends an exception to the user in the trace error level. The stack trace for this exception will be output when this error level is enabled.

The default implementation is a no-op for backward compatibility.

Specified by:

trace in interface Log

Parameters:

error - the error that caused this log

trace

public void trace(Supplier<String> content)

Description copied from interface: Log

Sends a lazily-computed message in the trace error level. The supplier is only evaluated if trace is enabled.

The default implementation is a no-op for backward compatibility.

Specified by:

trace in interface Log

Parameters:

content - the message supplier

trace

public void trace(Supplier<String> content,
 Throwable error)

Description copied from interface: Log

Sends a lazily-computed message (and accompanying exception) in the trace error level. The supplier is only evaluated if trace is enabled.

The default implementation is a no-op for backward compatibility.

Specified by:

trace in interface Log

Parameters:

content - the message supplier

error - the error that caused this log

debug

public void debug(CharSequence content)

Description copied from interface: Log

Sends a message to the user in the debug error level.

Debug is intended for messages that help users investigate their build — for example, why a module was recompiled or what classpath was resolved. For Maven core internals, use Log.trace(CharSequence) instead.

Specified by:

debug in interface Log

Parameters:

content - the message to log

debug

public void debug(CharSequence content,
 Throwable error)

Description copied from interface: Log

Sends a message (and accompanying exception) to the user in the debug error level. The error's stacktrace will be output when this error level is enabled.

Specified by:

debug in interface Log

Parameters:

content - the message to log

error - the error that caused this log

debug

public void debug(Throwable error)

Description copied from interface: Log

Sends an exception to the user in the debug error level. The stack trace for this exception will be output when this error level is enabled.

Specified by:

debug in interface Log

Parameters:

error - the error that caused this log

debug

public void debug(Supplier<String> content)

Specified by:

debug in interface Log

debug

public void debug(Supplier<String> content,
 Throwable error)

Specified by:

info

public void info(CharSequence content)

Description copied from interface: Log

Sends a message to the user in the info error level.

Specified by:

info in interface Log

Parameters:

content - the message to log

info

public void info(CharSequence content,
 Throwable error)

Description copied from interface: Log

Sends a message (and accompanying exception) to the user in the info error level. The error's stacktrace will be output when this error level is enabled.

Specified by:

info in interface Log

Parameters:

content - the message to log

error - the error that caused this log

info

public void info(Throwable error)

Description copied from interface: Log

Sends an exception to the user in the info error level. The stack trace for this exception will be output when this error level is enabled.

Specified by:

info in interface Log

Parameters:

Parameters:

content - the message to log

warn

public void warn(CharSequence content,

Specified by:

error in interface Log

Parameters:

content - the message to log

error

public void error(CharSequence content,
 Throwable error)

Description copied from interface: Log

Sends a message (and accompanying exception) to the user in the error error level. The error's stacktrace will be output when this error level is enabled.

error in interface Log

Parameters:

error

public void error(Throwable error)

isDebugEnabled

public boolean isDebugEnabled()

Description copied from interface: Log

Returns true if the debug error level is enabled.

isDebugEnabled in interface Log

Returns:

true if the debug error level is enabled

isInfoEnabled

public boolean isInfoEnabled()

Returns true if the info error level is enabled.

Specified by:

isInfoEnabled in interface Log

Returns:

true if the info error level is enabled

isWarnEnabled

public boolean isWarnEnabled()

child

public Log child(String name)

Description copied from interface: Log

Returns a child logger whose name is derived from this logger's name by appending a dot and the given suffix.

For example, if a plugin's logger is named "org.apache.maven.plugins.compiler.CompilerMojo", then child("diagnostics") returns a logger named "org.apache.maven.plugins.compiler.CompilerMojo.diagnostics". This lets sub-components log under an independently filterable name without requiring a separate injection point.

The default implementation returns this, so existing Log implementations continue to work without changes. Implementations that wrap a hierarchical logging backend (such as SLF4J) should override this to create a real child logger.

Specified by:

child in interface Log

Parameters:

name - the suffix to append (must not be null or blank)

Returns:

a child logger — never null
