Subject RE: How to redirect javac task errors to a separate file
Date Wed, 11 Feb 2004 22:48:23 GMT
I don't think it is an IDE feature. It could be easily incorporated in ant.
Consider following example where I have deliberately introduced compiler
error.

when I run "c:\build>javac testMe.java 2> error.txt" from DOS command line I
get following output

"testMe.java:3: class test is public, should be declared in a file named
test.java
public class test
       ^
1 error"


whereas if I use ant <javac> task I get following output:

init:

Clearly the ant output has lots of information and it is very difficult to
locate actual compilation error. In our actual project we have more than
3000 classes. You can imagine how the output will look with ant! Developers
will have hard time locating compilation errors with the output like that!!
Its very unfortunate for the tool like ant to lack feature of providing
useful build reports to developers.
For now I will make use of <exec> to launch a shell script that summarises
error output in nice html files that provide link to actual source code.


Thanks,

Sounds like you want an IDE.  Exactly what output are
you getting from the command line that you can't get
with <javac> or <exec>?
