将appfuse导入到Eclipse中，发现在Build Path下的Maven Dependencies下缺少 tools-1.5.0.jar
寻找N久，总算在stackoverflow http://stackoverflow.com/questions/5273792/missing-tools-jar-in-local-repository-breaks-m2eclipse
中找到解决方案，下载该jar包，放到.m2下去。
Download http://repository.ops4j.org/maven2/tools/tools/1.5.0/ and put the jar in the C:\Documents and Settings\Administrador\.m2\repository\com\sun\tools\1.5.0
