public class XmlLogger extends java.lang.Object implements BuildLogger
Generates a file in the current directory with an XML description of what happened during a build. The default filename is "log.xml", but this can be overridden with the propertyXmlLogger.file. This implementation assumes in its sanity checking that only one thread runs a particular target/task at a time. This is enforced by the way that parallel builds and antcalls are done - and indeed all but the simplest of tasks could run into problems if executed in parallel.- See Also:

Method Detail
-
buildStarted
public void buildStarted(BuildEvent event)
Fired when the build starts, this builds the top-level element for the document and remembers the time of the start of the build.- Specified by:
buildStartedin interfaceBuildListener- Parameters:
event- Ignored.
-
buildFinished
public void buildFinished(BuildEvent event)
Fired when the build finishes, this adds the time taken and any error stacktrace to the build element and writes the document to disk.- Specified by:
buildFinishedin interfaceBuildListener- Parameters:
event- An event with any relevant extra information. Will not benull.- See Also:
BuildEvent.getException()
-
targetStarted
public void targetStarted(BuildEvent event)
Fired when a target starts building, this pushes a timed element for the target onto the stack of elements for the current thread, remembering the current time and the name of the target.- Specified by:
targetStartedin interfaceBuildListener- Parameters:
event- An event with any relevant extra information. Will not benull.- See Also:
BuildEvent.getTarget()
-
targetFinished
public void targetFinished(BuildEvent event)
Fired when a target finishes building, this adds the time taken and any error stacktrace to the appropriate target element in the log.- Specified by:
targetFinishedin interfaceBuildListener- Parameters:
event- An event with any relevant extra information. Will not benull.- See Also:
BuildEvent.getException()
-
taskStarted
public void taskStarted(BuildEvent event)
Fired when a task starts building, this pushes a timed element for the task onto the stack of elements for the current thread, remembering the current time and the name of the task.- Specified by:
taskStartedin interfaceBuildListener- Parameters:
event- An event with any relevant extra information. Will not benull.- See Also:
BuildEvent.getTask()
-
taskFinished
public void taskFinished(BuildEvent event)
Fired when a task finishes building, this adds the time taken and any error stacktrace to the appropriate task element in the log.- Specified by:
taskFinishedin interfaceBuildListener- Parameters:
event- An event with any relevant extra information. Will not benull.- See Also:
BuildEvent.getException()
-
messageLogged
public void messageLogged(BuildEvent event)
Fired when a message is logged, this adds a message element to the most appropriate parent element (task, target or build) and records the priority and text of the message.- Specified by:
messageLoggedin interfaceBuildListener- Parameters:
event- An event with any relevant extra information. Will not benull.- See Also:
BuildEvent.getMessage(),BuildEvent.getException(),BuildEvent.getPriority()
-
setMessageOutputLevel
public void setMessageOutputLevel(int level)
Set the logging level when using this as a Logger- Specified by:
setMessageOutputLevelin interfaceBuildLogger- Parameters:
level- the logging level - seeProjectclass for level definitions
-
setOutputPrintStream
public void setOutputPrintStream(java.io.PrintStream output)
Set the output stream to which logging output is sent when operating as a logger.- Specified by:
setOutputPrintStreamin interfaceBuildLogger- Parameters:
output- the output PrintStream.
-
setEmacsMode
public void setEmacsMode(boolean emacsMode)
Ignore emacs mode, as it has no meaning in XML format- Specified by:
setEmacsModein interfaceBuildLogger- Parameters:
emacsMode- true if logger should produce emacs compatible output
-
setErrorPrintStream
public void setErrorPrintStream(java.io.PrintStream err)
Ignore error print stream. All output will be written to either the XML log file or the PrintStream provided to setOutputPrintStream- Specified by:
setErrorPrintStreamin interfaceBuildLogger- Parameters:
err- the stream we are going to ignore.
