You can't do it that way: a given target can only have one command
script to build it (unless you use double-colons but that's a while
different story).
You'll need to either add the JAVAC line to the same script as the JUNIT
line, like:
$(TESTCLASSES): Test%: %
$(JAVAC) $<
$(JUNIT) $(patsubst %.class,%,$@)
The disadvantage here is if the unit test fails, the class is still
created so it won't be run again. You could, of course, write shell
commands to delete the file for you when the unit test fails.
Or you could put the unit test into another rule, something like:
RUNTESTCLASSES = $(TESTCLASSES:%=run.%)
test: $(RUNTESTCLASSES)
$(RUNTESTCLASSES): run.% : %
$(JUNIT) $(patsubst %.class,%,$<)
@touch $@
or whatever.
