Class CommonsLoggingListener

java.lang.Object

org.apache.tools.ant.listener.CommonsLoggingListener

All Implemented Interfaces:

java.util.EventListener, BuildListener, BuildLogger

public class CommonsLoggingListener
extends java.lang.Object
implements BuildListener, BuildLogger

Jakarta Commons Logging listener. Note: do not use the SimpleLog as your logger implementation as it causes an infinite loop since it writes to System.err, which Ant traps and reroutes to the logger/listener layer. The following names are used for the log: org.apache.tools.ant.Project.PROJECT_NAME - for project events org.apache.tools.ant.Target.TARGET_NAME - for target events TASK_CLASS_NAME.TARGET_NAME - for events in individual targets. In all target and project names we replace "." and " " with "-". TODO: we should use the advanced context logging features (and expose them in c-l first :-) TODO: this is _very_ inefficient. Switching the out and tracking the logs can be optimized a lot - but may require few more changes to the core.

Since:

Ant 1.5

Method Detail

buildStarted

public void buildStarted(BuildEvent event)

Signals that a build has started. This event is fired before any targets have started.

This event is fired before the project instance is fully configured. In particular no properties have been set and the project may not know its name or default target, yet.

.

Specified by:

buildStarted in interface BuildListener

Parameters:

event - An event with any relevant extra information. Must not be null.

buildFinished

public void buildFinished(BuildEvent event)

Signals that the last target has finished. This event will still be fired if an error occurred during the build..

Specified by:

buildFinished in interface BuildListener

Parameters:

event - An event with any relevant extra information. Must not be null.

See Also:

BuildEvent.getException()

targetStarted

public void targetStarted(BuildEvent event)

Description copied from interface: BuildListener

Signals that a target is starting.

Specified by:

targetStarted in interface BuildListener

Parameters:

event - An event with any relevant extra information. Must not be null.

See Also:

{@inheritDoc}.

targetFinished

public void targetFinished(BuildEvent event)

Description copied from interface: BuildListener

Signals that a target has finished. This event will still be fired if an error occurred during the build.

Specified by:

targetFinished in interface BuildListener

Parameters:

event - An event with any relevant extra information. Must not be null.

See Also:

{@inheritDoc}.

taskStarted

public void taskStarted(BuildEvent event)

Description copied from interface: BuildListener

{@inheritDoc}.

taskFinished

public void taskFinished(BuildEvent event)

Description copied from interface: BuildListener
