I have an ant build file with some eclipse defined ant tasks such as "eclipse.convertPath". I can run this script without problems from my IDE but I'm not able to run it from the command line using the eclipse antRunner. My command, executed on a freshly installed classic 3.6.1 IDE, looks like this: $ECLIPSE_HOME/eclipse -consolelog -nosplash -data $WORKSPACE -application org.eclipse.ant.core.antRunner -buildfile <path to build file> Ant complains that the eclipse.convertPath is undefined. I know that this task is registered by the o.e.core.resources bundle and I checked (using -console -noexit and then 'ss') that this bundle is started. It's status shows as ACTIVE so I'm a bit lost here. What am I doing wrong? Here's a full stack trace from the invocation: <path to build file>:2: Problem: failed to create task or type eclipse.convertPath Cause: The name is undefined. Action: Check the spelling.

An update. I found that I only run into problems if I use 'eclipse.convertPath' as a root element. If I move it into a target that I have my other targets depend on, then it works. Not sure why that is or why it works when running from the IDE but not from the command line.

I ran into a similar problem, and built a test program under Eclipse Indigo. The Eclipse class loader when executed from antRunner on the command line under the Indigo 3.7M3 build is (org.eclipse.equinox.launcher_1.2.0.v20100824b.jar): antTask classloader: org.eclipse.ant.internal.core.AntClassLoader parent classloader: sun.misc.Launcher.AppClassLoader If I run the same antTask under eclipse Galileo's antRunner the following class loaders are in use (org.eclipse.equinox.launcher_1.0.200.v20090520.jar): antTask classloader: org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader parent classloader: org.eclipse.osgi.baseadapter.BaseAdaptor.ParentClassLoader. According to the eclipse documentation, the plug-in class loader is *supposed* to be added as the parent class loader when an ant task contributed by a plug-in has headless=true, and eclipseRuntime=true set in the org.eclipse.ant.core.antTasks extension point. From the test results, it would appear that this is not the case. I can supply the test program if that helps. It is very reproducible.
