Hello all,
trying to do this (part of test.xml):
<buckminster.lastRevision property="lastRev"
readerType="svn"
repositoryLocation="http://svn-st.inf.tu-dresden.de/svn/reuseware/trunk/"/>
from an Ant actor using Headless Buckminster (latest Helios stable), I get:
ERROR: org.eclipse.core.runtime.CoreException: test.xml:7:
java.lang.NullPointerException
org.eclipse.core.runtime.CoreException: test.xml:7:
java.lang.NullPointerException
at
org.eclipse.buckminster.ant.AntRunner.handleInvocationTargetException(AntRunner.java:167)
at org.eclipse.buckminster.ant.AntRunner.run(AntRunner.java:322)
at
(...)
Caused by: java.lang.NullPointerException
at
org.eclipse.buckminster.subversion.GenericSession.listFolder(GenericSession.java:558)
at
org.eclipse.buckminster.subversive.internal.SubversiveSession.getDirEntry(SubversiveSession.java:279)
at
org.eclipse.buckminster.subversive.internal.SubversiveSession.getLastChangeNumber(SubversiveSession.java:290)
... 48 more
I think it goes wrong at listFolder at line 558 (Class
org.eclipse.buckminster.subversion.GenericSession). Looking at the
source, it seems to do this:
} finally {
monitor.done();
}
So I guess 'monitor' is null here, hence the NullPointerException. Is
this a bug? Maybe headless calls don't have a monitor?
Note that if I instead use workingCopy (instead of repositoryLocation)
it does work...
Thanks,
Dennis

Hello Henrik,
Yes, looks like it. I marked the bug as duplicate.
I'm using the Helios stable release, not the maintenance release... How
can I install Buckminster maintenance release using the headless
director? Or do I have to wait for Helios SR1?
Thanks,
Dennis
