no, unless you hand code  stuff

multi cpus are invaluable for finding race stuff in server side code; you
can get a bit over 1 cpu flat out (say 100% and 20%) with file IO on cpu#2
today.

javac in multiple threads?

[Mr. Tomcat]

As of 1.4.1, javac is now threadsafe.  Does Ant (as of 1.5) support
multiple compilation threads?  If it did, a dual-CPU machine might be
able to compile almost twice as fast using ant, which would be cool of
course, and which might influence me to get a dewlie for my next desktop
machine.

problems with chmod

[Jennifer Moter]

I'm having problems making a shell script executable:
  

doesn't do anything. Since this is a direct copy from the online docs,
I was pretty sure it would work.  
I'm using ant 1.5RC1 with cpptasks.jar version 1.0b

Does anyone know of a fix for this task?

Lok at , but it's got some

You can use 2 build files or at least call 2
separate targets what start 2 different

newbie question: start an asynch process

[Erik.Ostermueller]

Hi all,

Didn't see this in the faq.
I want to write an ant task that will start an appserver
followed by a process that will start a web server.

How can I use ant to start the first process, the appserver,
asynchronously?
The attribute fork='true' doesn't seem to do the trick.

I'm running win2k.

Thanks in advance,

Re[2]: Can't get linkoffline to work with task

[Jacob Kjome]

Hello joel,

Are you sure that the URL's that point to the classes in the Java API
are valid when you do this?

In my build.properties file, I set the following:

javadoc.jdk.offline=true
javadoc.jdk.packagelistLoc=C:/j2sdk1.4.1/docs/api/

  note that I tried the above packagelistLoc with and without the
  trailing slash with no difference observed.  I also tried a
  file:/// URL and tried doing .../api/package-list, both of which
  resulted in no links created at all.

I have the following set up to run in Javadoc...



I echoed the values for the above values.  They are...





[echo] true
[echo] http://java.sun.com/j2se/1.4/docs/api/
[echo] C:/j2sdk1.4.1/docs/api/


However, the result of the link to the Object class from the javadoc
of one of my classes ends up being this:

file:///D:/myclasses/repository/enhydra/Barracuda_2002-09-23/Barracuda/javadocs/http://java.sun.com/j2se/1.4/docs/api/java/lang/Object.html


That URL is totally invalid.  How did you set things up to get valid
URL's generated pointing to the offline location of your jdk docs

failed Junit test -> file permission error? Ant 1.5 bug?

[otisg]

Hello,

I am running JUnit tests via Ant 1.5 on
Windows, and whenever a test fails Ant
reports it as file permission error, which
is completely incorrect.

Here is an example:

[junit] Running
net.wgen.amp.model.AmpUserTest

Is this a known problem?

I've been trying to get around this for
about a week now, but I'm stuck at this
point, unfortunately :(

Any help would be very, very much appreciated!

Thanks,
Otis

How can I repeat a failed task?

[Chris Gunn]

I created build file to create a label in VSS, then get from that label,
then build my application.  The problem is that the get from label often
fails due to networking problems.  Is there a way to tell ANT to repeat a
task until it succeeds, or to try several times before failing?

Hi Jacob and All,

I finally found where was my mistake, but I believe this revealed a possible RFE for

Could it be and RFE to improve Ant  task error reporting in such a case?
