I checked out today's ant trunk , but when I try to build it by running bootstrap.bat , the following info "src\main\org\apache\tools\ant\taskdefs\Concat.java:489: 在相应的 try 语句主体中 不能抛出异常 java.io.IOException } catch (IOException e) { ^"
I think we'd need a little more context than that single line - do you have a full stack trace available? I can test the trunk + bootstrap if you like, but it worked for me yesterday. Kev
