Preamble :
- I'm new to eclipse
- I'm new to buckminster
- i''m quite new to java (wrote my last code in the late millenium)

I've got the job to build a p2-site for some already existing plugins and features. After some weeks of struggling and desperation I've managed to understand what a BOM is good for. I created it with Eclipse following the instructions from the BuckyBook. Now I've got stuck. When I want to materialize my workspace :

buckminster --loglevel DEBUG -data /tmp/mausi importtargetdefinition my_bom.bom

I get the message :

"The target file is in an invalid format and could not be opened"

Only 1 (one) Google hit : the source code which generates this message. (ok, now there are two Wink

).

I'm using the last eclipse version (3.6.1), and also the most recent buckminster 3.6.

The message is generated by 'org/eclipse/pde/internal/core/target/TargetDefinitionPersis tenceHelper.java', method 'initWithXML'. I've changed the source code to get some information. The changed source code :

DocumentBuilder parser = DocumentBuilderFactory.newInstance().newDocumentBuilder();
StackTraceElement[] trace = new Throwable().getStackTrace();
System.out.println(" ************************************************************ ************* ");
System.out.println("Start of desperation : ");
System.out.println("definition : " + definition);
System.out.println("InputStream : " + input);
parser.setErrorHandler(new DefaultHandler());
Document doc = parser.parse(new InputSource(input));
System.out.println("Document : " + doc);
Element root = doc.getDocumentElement();
System.out.println("root : " + root);
System.out.println(root.getNodeName ());
if (!root.getNodeName().equalsIgnoreCase(ROOT)) {
System.out.println("root.getNodeName :" + root.getNodeName ());
System.out.println("ROOT :" + ROOT);
for(int i=1; i<trace.length; i++){
System.out.println(trace[i]);
}
throw new CoreException(new Status(IStatus.ERROR, PDECore.PLUGIN_ID, Messages.TargetDefinitionPersistenceHelper_0));
}

And here is the output :

importtargetdefinition 'my_bom.bom'

Doing full workspace refresh
Waiting for jobs to end
The target file is in an invalid format and could not be opened.

A work-mate tried to do the very same task, and got the very same error message.
Just checking out our source code via cquery works like a charm.

It doesn't matter how big the BOM is. Even an empty BOM (just build an empty feature) behaves the same way.

The big question is : Why does buckminster generate a BOM which can't be read by headless buckminster ?

Thanx in advance !
