Subject RE: Question regarding -Xlint:unchecked
Date Sat, 16 Dec 2006 07:11:06 GMT

Hi Antoine, 
That is acctually correctly. As you can see, when the second build.xml invokes the "compile"
target in the first build.xml, the  "inheritAll" is set to false, which means by default no
valuable defined in the second build.xml is passed to the first one, only when it is explicitly
specified . So the value ${src.dir} has different value for each build.xml file.

Hello Chun Ji,

please check the path that you pass in the dir attribute of the <ant/ 
 > invocation. Probably, it should be <ant dir="."/> and not <ant  
dir="${src.dir}" . You want this attribute to be the basedirectory of  
the build file that you invoke.
