After digging into the dependency tree described in each module's pom.xml
for several days, I found that you're right. It's my fault, not Maven's.
It's because my code depends some other modules which I didn't put it into
pom.xml explicitly. And I'm adding them into the corresponding pom.xml.
Thank you for directing me back to the right track!

However, I'm curious that I succeed to compile the project after several
compilation failure. How does it happen? I've passed the parameter 'clean
install -Dmaven.test.skip=true --update-snapshots --batch-mode --fail-fast
--debug -Dmaven.compiler.forceJavacCompilerUse=true
-Dmaven.compiler.verbose=true' to Maven, but it doesn't get the same error
when I compile the project the second time. And it mislead me to blame Maven
;-)

Could anyone explain the somewhat weird behavior of Maven? Thanks.
