Build issue

[rhills]

Yesterday, when building JBoss Profiler (using the default task), I ran into a problem:

Using ANTRC_PRE.BAT
Buildfile: build.xml

init:

prepare:

agent:
 [delete] Deleting directory D:\dev\java\jboss\projects\JbossProfiler2\build
 [javac] Compiling 82 source files to D:\dev\java\jboss\projects\JbossProfiler2\build
 [javac] D:\dev\java\jboss\projects\JbossProfiler2\src\main\org\jboss\profiler\agent\AbstractTransformer.java:34: error while writing org.jboss.profiler.agent.AbstractTransformer: D:\dev\java\jboss\projects\JbossProfiler2\build\org\jboss\profiler\agent\AbstractTransformer.class (The system cannot find the path specified)
 [javac] public abstract class AbstractTransformer implements Transformer {

 [javac] 1 error

I did a "clean" and the problem went away.

Today, after a number of successful builds, I'm getting this problem again. This time it seems persistent, I've tried doing a "clean", followed by "dist" several times, but keep getting the same error. No classes are compiled. I've not changed any java code so I'm not sure why this error was triggered yesterday and why it's started again today.

Forgot to mention,

Ant 1.7.0
OS: Windows XP Professional SP3

Strange - I don't see this problem; and the file hasn't been changed for some time.

I use Ant 1.7.1 and Sun JDK-1.5.0_16...

[rhills]

I just upgraded ant to 1.7.1 but the problem persists.

I was using JDK 1.5.0_09 (which is my default for another project) but I've also tried it with JDK 1.6.0_07 - same result each time.

It's very frustrating, and it has me dead in the water ATM.

I'll try the windoze fixall - reboot and try again. Maybe there's something funny going on in my environment somewhere. It's strange that I had the problem yesterday for a short while but have built numerous times since without any problem until recently.

I have added eol-style=native to the files -- maybe that helps on Windows...

Have you tried with 5.0_16 or 6.0_10 ?

[rhills]

I think it's a problem with windoze and java and file/directory deletion. I'm sure I've seen it in the past. That said, I'm also using Tortoise SVN, so it may be contributing somehow.

The problem went away when I rebooted my notebook. I tend to use "resume" mode a lot as I travel to work by train and I just shut the lid when I get to my station. This afternoon on the way home, the problem happened again. this time I noticed that the "build" directory didn't go away after a "clean". If I manually deleted the "build" directory, there'd be no error, but it wouldn't go away. I tried via both file mangler and via the command line, same result. After rebooting, the "build" directory was gone and the build process worked again.

Anyway, thanks for adding the eol-style, I'll see if it helps. I might also try a different version of java, though I'd prefer to stick with GA releases of 6 where I can.

[rhills]

Actually, there's one other thing that might help. Could you add the svn:ignore property to the "build" and "dist" directories?

If nothing else, it would help reduce clutter when committing files (or creating patches).

[jesper.pedersen]

Done in rev516

[rhills]

Thanks for that. Building cleanly ATM, but I'll reserve my judgement for a day or so!

At least the clutter has gone :-)
