My ant build fails with this error: "error running javac.exe compiler"
Doesn't give me any other information.
javac should be a pretty standard target, shouldn't it?
is it not finding the exe?
What am i missing?
Thanks in advance,
Nilesh
[UPDATE] - installed Ant 1.8.1, tried running ant from command line, got the same error, set JAVA_HOME, and command line worked.
Set eclipse to use Ant 1.8.1, added tools.jar to the classpath, still no dice.
ARRRGH!

Your problem was user error, not a bug. You were using a JRE and
expected Ant to find a javac executable, which simply isn't included in
any JRE.
JAVA_HOME is a Sun-specific thingy that Eclipse chooses not to use
(mostly because system-wide environment variables are a bad idea in
general); as you found, there is an easy way to tell Eclipse about any
number of JREs and JDKs to use to build and run your apps. That
flexibility is powerful and a designed feature.

Eric,
Technically, your reply is accurate. However, a problem that recurs frequently, which causes users dismay and delay, while not a bug, is a problem that 'bugs' people, and should be addressed. A quick search of the web shows that this 'problem' or 'bug' occurs frequently, and the error message is not informative, thus dismay and delay. Is there a chance that the error message could be changed a bit so that the delay would be less?
I'm always hoping for increased user friendliness in every tool I use, even the very best ones. I love the tools that are provided to me; eclipse is excellent.
