Why am I getting compile errors when library is in the classpath? [message #497133]

Hi,

I'm using Eclipse Galileo for Mac 10.5.6. I have this entry in my ROOT_PROJECT/service/.classpath file ...

<classpathentry sourcepath="MAVEN_REPO/javax.mail/java-sources/mail-1.4-sources.jar " kind="var" path="MAVEN_REPO/javax.mail/jars/mail-1.4.jar"></classpathentry >

However, when I open a .java source file from within the ROOT_PROJECT/service/src/main/java/package/of/file/ directory, Eclipse complains about the import

import javax.mail.MessagingException;

underlining "javax.mail" and saying, "The import javax.mail cannot be resolved". I have verified the classpath entry above contains the class in question. Any ideas how to troubleshoot why it is telling me this? There are other imports it is also complaining about in a similar way.

Is the MAVEN_REPO classpath variable set to what you would expect?

Hi, Yes, MAVEN_REPO is set correctly. One thing I didn't include in here is that I have a .classpath file in my root project folder and then there are .classpath files in my sub-projects. I am getting the lingering suspicion that Eclipse cannot "merge" nested .classpath files. Any thoughts on that? - Dave

Eclipse can't handle nested projects at all. That is one of the (many)
mismatches between Maven and Eclipse. The M2Eclipse plugin attempts, with
varying success, to resolve these. You might want to give it a try.
