Subject RE: compile attribute of JAVAC task
Date Fri, 26 Mar 2004 23:10:36 GMT
If you are using a compiler < 1.4 in <javac> task (as you mention), it will not recognize
the -source flag.
 
I suggest either to remove the "source" flag from your <javac> task or let ant to compile
your source files using JDK 1.4
 
Regards

Subject: compile attribute of JAVAC task



Hi All,

 

We are running ANT under 1.4 VM. But, compiling the code with javac 1.3. ( possible through
Javac task's executable attribute ).

We have also turned the "source" attribute of javac task. [mainly for Assert statement compatibility]

 

But, are running into compilation errors "javac: invalid flag: -source"

This behavior seems to run against Ant's own documentation of the "source" attribute to the
javac task.

 


source

Value of the -source command-line switch; will be ignored by all implementations prior to
javac1.4 (or modern when Ant is not running in a 1.3 VM) and jikes.
If you use this attribute together with jikes, you must make sure that your version of jikes
supports the -source switch.
Legal values are 1.3, 1.4 and 1.5 - by default, no -source argument will be used at all.

 

Any ideas how to get around the problem? All inputs appreciated.

 

Thanks,

VSarsam
