| OpenJPA enhancer task works on cmd line, fails in Eclipse 3.5.1 [message #504249] |

(This is my third try at posting this. The first two never showed up. My attempts were yesterday, several hours apart, so I'm pretty sure I waited long enough.)
I have an app using JDK 1.6, Eclipse 3.5.1, and OpenJPA 1.2.1. OpenJPA has an "enhancer" task that modifies the bytecode of domain classes. My Ant build script to do this works perfectly fine from the command line. When I run it from Eclipse, however, it fails with the build output that follows this.
Following the build output is the relevant portion of my build.xml file. My persistence.xml file is in "src/java/META-INF/persistence.xml", which is covered in the classpath (this is mentioned as one of the possible causes in the error message).
What could I be doing wrong here?
Ant build from Eclipse:
------------

org.apache.openjpa.util.MetaDataException: MetaDataFactory could not be configured (conf.newMetaDataFactoryInstance() returned null). This might mean that no configuration properties were found. Ensure that you have a META-INF/persistence.xml file, that it is available in your classpath, or that the properties file you are using for configuration is available. If you are using Ant, please see the <properties> or <propertiesFile> attributes of the task's nested <config> element. This can also occur if your OpenJPA distribution jars are corrupt, or if your security policy is overly strict.

My guess would be a path problem. Check the launch configuration for
your ant script in Eclipse. Make sure the Working Directory on the JRE
tab points to the correct location.

Well, that wasn't it, but that made me look at something that seemed suspicious, so I was able to figure it out. For some reason that I don't understand, the run configuration for the script didn't include the project, so it didn't have any of the classpath of the project. I didn't see any way to add the "project", so I had to manually add all the jars for the project. Once I did that, Ant targets ran fine from Eclipse.
