Hi Jerod,

I need to run gradle with a 1.4 jdk, specifically IBM's 1.4 jdk.
The reason
for this is that I need to run a websphere EJB deploy ant task to
create
some EJBs and I have found that this is dependent on IBM's was 5.1
jdk,
which is version 1.4.2. I am on a Windows XP machine, so I have
the regular
windows cmd and also cygwin. When I try to use gradle (even gradle
-v) in
cygwin if my JAVA_HOME is set to the 1.4 JDK, I get the error:
The java class could not be loaded.
java.lang.UnsupportedClassVersionError:
org/gradle/BootstrapMain (Unsupported major.minor version 49.0)
This happens both with the current snapshot of gradle and the
current svn
version of gradle, even if I build the source with the 1.4 jdk.
In Windows cmd, both the current snapshot and the current svn built
with 1.4
jdk appear to work. I can execute gradle -v and gradle clean runs
quickly,
but if I actually try to build something, gradle starts quickly and
each
successive project configuration takes more time until eventually
it runs
out of memory. I've never used gradle in cmd so I guess it doesn't
surprise
me that it doesn't work, but how can I get gradle running with
IBM's 1.4 JDK
in cygwin?
Any thoughts would be very much appreciated.
As we use Java 5 features, Gradle can't run on a JDK 1.4 right now.
There is a retroweaver project though which makes 1.5 bytecode 1.4
compatible. I know that the Groovy project is using this. I need to
have a look into this or you might have. I would be cool to have a
jdk1.4 compatible Gradle distribution.
