Hi, Thomas,
Apparently we are not doing such a great job tracking dependencies of
generated files on Java classes. This is a bug and probably deserves
a JIRA so that we don't lose track of it.
Examining the code for post-compiling generated Java files confirms my
suspicion that we are not constructing a sourcepath for the javac
compiler at all -- only the classpath. When you open the JIRA, please
include a request that an appropriate sourcepath is constructed.
Your output indicates that you're invoking x10c from elsewhere. As a
temporary workaround, try running x10c from the source directory --
that should pick up the Java files in the same directory, as javac
puts "." on the sourcepath by default.
Hope this helps,
Igor
