ECLIPSE with ANT javac target

Hi,

I want to re-use a Java project i used to compile with an ant
build.xml file.
I want to import this project into Eclipse 2.1 because of the rich
functionalities of this IDE and re-use this build.xml file to compile.

But whenever i launch the compile target, i've got this error:

compile:
[javac] Compiling 1 source file
[javac] Modern compiler not found - looking for classic
compiler
[javac] BUILD FAILED:
file:D:/eclipse/workspace/HW/projectBuilder.xml:4: Cannot use classic
compiler, as it is not available. A common solution is to set the
environment variable JAVA_HOME to your jdk directory.

My JAVA_HOME variable in set to C:\jdk1.3.1_6 but do i need to
indicate anywhere in ECLIPSE also ?

Thanks,
C.Blondel

You need a jdk 1.4.1 or above (modern compiler)

Hi,

I had the same problem. One fix is to add the tools.jar file to the
Classpath of the ANT Runtime Preferences.

Menu: Window
-> Preferences
Sector: Ant
-> Runtime
Add tools.jar to Classpath:
-> "Add JARs..." button

Javac runs in two modes, modern and classic. You can change the mode
via command line args to javac. You will have to change your ANT
script to use the modern compiler.

It also looks like your Eclipse contains a Javac of JDK 1.1 or 1.2.
The modern compiler is available only in 1.3 or 1.4.
