Hi,
I am running the following code to run this ant file.
private void antRun(){
File buildFile = new File("C:\\Documents and Settings\\tharanga\\My
Documents\\IBM\\wssitedev51\\workspace\\BundleDeployer\\build.xml");
if(buildFile.exists()){
Project p = new Project();
p.setUserProperty("ant.file", buildFile.getAbsolutePath());
DefaultLogger consoleLogger = new DefaultLogger();
consoleLogger.setErrorPrintStream(System.err);
consoleLogger.setOutputPrintStream(System.out);
consoleLogger.setMessageOutputLevel(Project.MSG_DEBUG);
p.addBuildListener(consoleLogger);
try {
p.fireBuildStarted();
p.init();
ProjectHelper helper = ProjectHelper.getProjectHelper();
p.addReference("ant.projectHelper", helper);
helper.parse(p, buildFile);
p.executeTarget(p.getDefaultTarget());
}
catch (BuildException e) {
p.fireBuildFinished(e);
}
} else {
System.out.println(buildFile.getAbsolutePath()+" does not exists");
}
After the verbose mode I recived the stacktrace as follows.
BUILD FAILED

Hello,
how do you run this programmatically ?
one common source of null pointer exceptions in Ant API use is to forget to set
a project reference on task objects or datatypes. The null pointer exception
happens then as soon as the task or the datatype tries to log something.
if you have a NPE when using command line Ant, run
ant -verbose
(-verbose is a command line argument)
this will give you a stack trace.
Regards,
Antoine
