RE: [platform-ant-dev] Compiler Problem

Hmmm, you know, I don't know an explicit way to tell which VM eclipse chose.  You can tell in a  backwards way but looking at the Java VM preferneces and see which ones Eclipse has discovered.  The one you are currenly running should show up in that list.  I always explicitly tell eclipse which VM to use using hte -vm command line option.  If you are willing, perhaps try your test case and run eclipse with -vm <you jdk location>/bin/java.exe.  This will ensure you know which one you are running.

To tell the differnece between the JDK and JRE you'd likely have to look at the Java install locaiton and see if it has tools.jar etc (ie., all the JDK only stuff).  Even thne, there may be a JRE dir.  The above approach of explicitly indicating the JDK VM should clarify it all.

As far as I'm aware I'm running off the 1.3 JDK, at least I am when I run programs from the shell.  How do I make sure that eclipse is using the JDK rather than the JRE?
 
Dave.

Question for both Mark and Dave, are you running on a real JDK or just a JRE?  The theory is that the tools.jar (which contains the javac code) is not ending up on the class path.  The only real issue I can imagine is that you are running a JRE and JRE's don't come with tools.jar.  Can you confirm? 

As you've noted, if you use the workaround then the ant scripts don't work outside Eclipse.    You should on ly have to set the build.compile property if you explicitly want to use the Eclipse (JDT) compiler.

I don't think so, I had the same problem and found the
answer on the newsgroup. I believe it has something to
do with JAVA_HOME.

I'm just a user, or am I since this is Open Source!

Yeeha! Thanks mark that fixed the problem!

BTW is this documented somewhere?  It would be nice if it worked without
amending the build script so that it works in and outside eclipse.

Thanks again,

Dave
