Re: [Springframework-developer] Changes to build.xml to run autobuilds build on 1.5 as well

RE: [Springframework-developer] Changes to build.xml to run autobuilds build
on 1.5 as wellAFAIK, when building on JDK 1.5, you're always compiling
agains the 1.5 version of the standard libraries. We would get most value
out of an auto-build on 1.4 that actually compiles against the 1.4
libraries, to make sure that we didn't accentally use 1.5-only methods
somewhere.

I do compile on 1.4 before each release anyway, to check that everything
relevant still compiles there. Having this in the auto-builds would allow us
to catch any issues earlier, though.

  You're right, but I'll be adding support for running the unit tests on 1.4
as well... I was first thinking about adding a simple master build script
that executes the two builds (1.4 and 1.5) but the problem here is that the
'ant' task does not support forking of a new JVM and doing an 'exec' is not
an option, since I want to preserve the log files. JUnit does support the
fork (we're already doing it) and you can also specify a JVM to use.

  About building (compiling), I thought the behavior when building on 1.5 in
combination with adding the compatibility flag would be the same as with
building on 1.4, wouldn't it?

  Well, I don't object to such a property in general. But such a property
only
  makes sense if you intend to build the 1.4 version on JDK 1.5: I don't
think
  there's much point in that; building the 1.5 version only would be
  sufficient then.

  The capability of our build script to build on 1.4 is really just meant as
a
  fallback for users that want to do custom builds on their 1.4 JDK. The
only
  value we could add to the auto-builds is to check that building the 1.4
  version actually works *on JDK 1.4*, which we can't check by building on
JDK
  1.5...

    If nobody objects, I'll be modifying the build file to include an extra
  property that indicates whether or not you want to build on 1.5. I want to
  have the autobuild build for both 1.5 and 1.4 but I can't get this to work
  while maintaining the build numbers. To in addition to detecting the Java
  version automatically, there will be a property you can specify when
issuing
  an Ant command.
