Unexpected behaviour of Ant task logging

2003-03-28 - By Joern Engmann

Hi!

I found an unexpected behavior of the Ant task. When I use a special logger
in the parent process, normally I want to use the same logger type for the
sub process. At this time the Ant task uses DefaultLogger in any way.
Additionally its not possible to set a special Logger in the Ant task.

The following code should solve the Problem. It would be nice if it could be
in the next releases of Ant.

protected void initializeProject()
{
newProject.setInputHandler(getProject().getInputHandler());

Vector listeners = getProject().getBuildListeners();
final int count = listeners.size();
for (int i = 0; i < count; i++) {
newProject.addBuildListener((BuildListener)
listeners.elementAt(i));
}

if (output != null) {
File outfile = null;
if (dir != null) {
outfile = FileUtils.newFileUtils().resolveFile(dir, output);
} else {
outfile = getProject().resolveFile(output);
}
//changed Code
try {
out = new PrintStream(new FileOutputStream(outfile));
BuildLogger logger = null;
if (loggerName!=null)
{
logger =
(BuildLogger)Class.forName(this.loggerName).newInstance();
}
else
{
int i = listeners.size()-1;
while ((!(listeners.elementAt(i) instanceof BuildLogger))
&& (i > -1))
i--;
if(i > -1)
logger =
(BuildLogger)listeners.elementAt(i).getClass().newInstance();
else
logger = new DefaultLogger();
}
logger.setMessageOutputLevel(Project.MSG_INFO);
logger.setOutputPrintStream(out);
logger.setErrorPrintStream(out);
newProject.addBuildListener(logger);
} catch (Exception ex) {
log("Ant: Can't set output to " + output);
}
}
...
}

//additional code
protected String loggerName = null;
public void setLogger(String logger)
{
this.loggerName = logger;
}
