Hi Friends,
I'm having then following error when i execute my ant command as below.
D:\apache-ant-1.5.2\bin>ant -f afe-build.xml compileall
Buildfile: afe-build.xml
compileall:
[javac] Modern compiler is not available - using classic compiler
[javac] Compiling 53 source files to E:\Telenet-Maintenance\oasis\lib\classe
s
BUILD FAILED
D:\apache-ant-1.5.2\bin\afe-build.xml:99: Cannot use classic compiler, as it is
not available A common solution is to set the environment variable JAVA_HOME to
your jdk directory.
Total time: 1 second
D:\apache-ant-1.5.2\bin>echo %JAVA_HOME%
D:\jdk1.3.1
As you can see, my JAVA_HOME env . variable is properly set. Can anyone throw some light.
Thanks
Vikas
D:\apache-ant-1.5.2\bin>

Does your jdk home has a subdirectory \bin? Make sure you have complete sets of lib's etc there too. Sometimes, jdk files can be corrupted. If that's the case, download a new one.

I was having a similar problem running ant from within WSAD. I found that I needed to pass
-Dbuild.compiler=org.eclipse.jdt.core.JDTCompilerAdapter
as an argument so that it would know where to find the compiler.
Hope this helps!

I found this long ago and took it a step further....

<!-- ****************************************************** -->
<!-- Determines whether being run from inside WSAD/Eclipse -->
<!-- and sets properties as needed -->
<!-- ****************************************************** -->
<target name="eclipse" if="eclipse.running">
<property name="build.compiler" value="org.eclipse.jdt.core.JDTCompilerAdapter" />
</target>

I then added this as a dependency to my build target, i.e.

<!-- **************************************************** -->
<!-- Compiles the source code -->
<!-- **************************************************** -->
<target name="compile" depends="eclipse,init" description="Compiles source code">
<javac destdir="${classes}" debug="true" deprecation="true">
<src path="${src}"/>
</javac>
</target>

I never have to worry about this problem now. And I don't have to explain the problem to anyone else that picks up my projects that contain a build.xml file, either...!
