essentially you can even compile with java 1.6 and use the 1.3 runtime
libraries and source 1.3 and target 1.3 and the resulting classes will
be just as good as compiling with java 1.3
the real issue you have is ensuring that the class and method
signatures that you have used in your code are only those for 1.4 or
earlier
that is where either a full set of unit tests or something like animal-
sniffer comes in.
unfortunately I have not released animal-sniffer from codehaus *yet*
so you'd have to use the original version from java.net
if you can wait a short while org.codehaus.mojo:animal-sniffer-maven-
plugin and you can use that (short time is a week or two)

its available i want to include into MANIFEST.MF
or is there a way to just confirm it

sorry, I missed your pom snippet on this small screen
your classes were compiled with java 1.4
your jar was packaged up by a java 1.5 jre

thanks for replying
is this means, that configuring compiler version / executable in
compiler
plugin will not have any effect on this??
i thought by classes are compiled with javac mentioned in
executable tag..

your code was compiled with java 1.5 in compatibility mode for 1.4
providing you have only used classes and methods only from the 1.4
runtime
libraries, everything will be fine
you need to use another tool to ensure that you have not
accidentally
used
some 1.5 methods (eg String.isEmpty())
animal-sniffer is one tool to do this check for you

Hi All,
I use Maven 2.2.1 and it runs on JDK 1.5 and above, but my
source code
is
not 1.5 compatible yet, so i configured my compiler plugin as
shown
below.
Everything works fine. but when i look into MANIFEST.MF of my
jar file
it
shows Build-Jdk: 1.5.0_13. So how do i confirm that my code were
compiled
with 1.4 only not with 1.5 ??
Please Help

<groupId>org.apache.maven.plugins</groupId>

<compilerVersion>IBM-JDK-1.4</compilerVersion>
Thanks
