这是我的Makefile:

REBAR=./rebar
REBAR_COMPILE=$(REBAR) get-deps compile

all: compile

compile:
    $(REBAR_COMPILE)

test:
    $(REBAR_COMPILE) skip_deps=true eunit

clean:
    -rm -rf deps ebin priv doc/*

docs:
    $(REBAR_COMPILE) doc

ifeq ($(wildcard dialyzer/sqlite3.plt),)
static:
    $(REBAR_COMPILE) build_plt analyze
else
static:
    $(REBAR_COMPILE) analyze
endif

我可以多次运行make compile和get

aromanov@alexey-desktop:~/workspace/gm-controller/lib/erlang-sqlite$ make compile
./rebar get-deps compile
==> erlang-sqlite (get-deps)
==> erlang-sqlite (compile)

然而，由于某些原因，运行make测试总是失败

aromanov@alexey-desktop:~/workspace/gm-controller/lib/erlang-sqlite$ make test
make: `test' is up to date.

即使文件没有编译。问题是，为什么?

直接运行相同的命令也可以:

aromanov@alexey-desktop:~/workspace/gm-controller/lib/erlang-sqlite$ ./rebar get-deps compile skip_deps=true eunit
==> erlang-sqlite (get-deps)
==> erlang-sqlite (compile)
Compiled src/sqlite3_lib.erl
Compiled src/sqlite3.erl
==> erlang-sqlite (eunit)
