SourceFile attribute wrong when compiling with eclipse batch compiler [message #636982]

Hi

We're experimenting with moving our build from javac to the Eclipse
batch compiler using Plexus [1]. Compilation works fine but source
attachments for the generated classes never work. The editor in JDT
always displays: "The source attachment does not contain the source for
the file FooAction.class". After comparing the byte code we discovered
that the SourceFile attribute has the full path to the file instead of
just the local name.

For example the Eclipse batch compiler would produce:
com/acme/FooAction.java

whereas javac would produce:
FooAction.java

I don't assume this a bug in the Eclipse batch compiler but rather in
the integration [2] [3]. You don't happen to have any pointers on where
to start looking?

Could you please open a bug report against JDT/Core with a source file and the corresponding .class files attached to it so that we can investigate it ?

I tried quickly to produce a .class file from a compilation unit inside a package and the source attribute looks ok.

So this is either a bug in the Plexus compiler or due to some specific settings.

It's a Plexus bug, not a JDT bug. We backported tycho-compiler-jdt and
everything is working fine now.
