Ant cannot find compiler

[Matthew Heaton <Ma...@apexlearning.com>]

I'm running ant on Win NT with Suns JDK 1.3, and had been successfully
running it for a number of weeks.  All of a sudden I started getting errors
and I don't remember changing any settings on my machine.

When I tried compiling java classes through ant I got the following error.

    [javac] Modern compiler is not available - using classic compiler

BUILD FAILED

C:\ace\build.xml:60: Cannot use classic compiler, as it is not available


My JAVA_HOME was set to c:\jdk1.3\jre and that had been working.  Then I
tried setting it to just c:\jdk1.3 and it compiled but Javadoc failed with
the following error:

Running javadoc...
  [javadoc] Generating Javadoc
  [javadoc] Javadoc execution
  [javadoc] Error: could not open `c:\jdk1.3\lib\jvm.cfg'


I've tried everything I can think of an no solution.

The only real way to do it is to add another target to project that lists
all targets you want to run in depends tag.

Which version of Ant do you use?

Multi-target builds

[James Bucanek <su...@gloaming.com>]

Greetings,

I just started working with Ant this week, and have run across a 
potential annoyance.

It appears that Ant only builds one target at a time.  So when 
building multiple targets, Ant builds each target successively.  The 
result being that any common targets are executed multiple times.

I've found a hack around this:

     <target name="init" unless="init.complete">
         <echo message="init executing..."/>
         <tstamp/>
         <property name="init.complete" value="true"/>
     </target>

So, is there some other way of either (a) keeping tasks from running 
more than once or (b) building the entire tree of targets to be built 
in one pass?

Thanks,
