You have left over files in `target` after switching between the

No it's not the problem.
They are _source_ files.
Run clean before switching between branches and you should be OK.
If they would be removed, that would not be OK! ;-)

Hello.
There are two branches for Commons Math.
For one, the top-level Java package is
org.apache.commons.math4
For the other, it is
org.apache.commons.math3
Unless I'm mistaken, this should imply that maven tries to compile
only files under either
src/main/java/org/apache/commons/math4
src/test/java/org/apache/commons/math4
or
src/main/java/org/apache/commons/math3
src/test/java/org/apache/commons/math3
No, Maven compiles everything under src/[main|test]/java by default.
You could change that to
src/main/java/org/apache/commons/math4
but then the compiler would complain about mismatched package names
But it happens that I have currently files in "math3" not currently
checked in into git: those are new files which git does not remove
when switching branches.
That's the problem - spurious files in the workspace.
Then when starting a compilation in "master" (where the top-level
is "math4"), lots of compilation errors occur.
The "source" top-level directories do not seem to be specified
in the project's POM.
No, because Maven defaults to the standard directory layout.
Can the parent be changed in order to produce the desired
behaviour?
Well, you might be able to exclude all files under math3/math4 but
it
will be tricky to do and non-standard.
Or is there a workaround?
Remove the spurious files ...
Is there a better way to handle the situation (short of manually
moving the source files back and forth)?
Why not use two checkouts and switch between them instead of
switching
the contents of a single checkout?
Thanks,
Gilles
