re: using jdk1.5alpha for javac
Hello,
I am trying to figure out how to get the javac task to work, but I am
having a problem with one option.
I am trying
<javac
fork="yes"
executable="/usr/j2sdk1.5.0/bin/javac"
source="1.5"
srcdir="...">
Everything works until I try source="1.5", then I get an error.
I want to start trying to use some of the new features (such as
autoboxing) and see if it works fine on the production server running
jdk1.4.2.
I can't just set my path to point to the 1.5 jdk because I have a
problem with junitreport, which appears to be a bug in xalan, so I just
want to compile with 1.5, then run my tests with 1.4.2.
Thank you for any suggestions.

Thank you for the response. I will try this today.

You can set you path to point jdk 1.5 and then just use this
source="1.5" :
<javac destdir="${build.classes.dir}"
debug="on"
optimize="off"
source="1.5"
deprecation="on">
<src path="${src.dir}"/>
<classpath refid="compile.classpath" />
</javac>
In order to do that you must patch latest version of xalan.jar's file
Encodings.properties.
Just add new line to end of file. Put this xalan.jar to
\j2sdk1.5.0\jre\lib\endorsed directory and it should work.
It's not a xalan bug it is bug in java.util.Properties.class
I filed bug report on that and it should be visible in JDC in few
working days.
Bug-ID: 4982523
synopsis : REGRESSION: Properties method load() drops end of file in a comment
description : /*
* If the last line of a properties file is a comment line,
* and if that line ends with end-of-file (no line terminator),
* then that comment line is mistakenly loaded as a property.

Rgds,

Without any warnings? I'm surprised. Maybe it's just the Linux
version that is unwilling to accept -source 1.3 or to create -target
1.1.
The short story is that there is no real support for JDK 1.5 yet.
I've added a few things to CVS HEAD but it is far from finished.
But at least Ant would detect Java 1.5 with this and allow -source
1.5, maybe I should merge the parts we have over to the 1.6 branch so
it gets into 1.6.1 - I don't see any chance of supporting the new
javac API, I've forgotten the JSR number, for the planned release
date.
Antoine, what do you think? I'm talking about
<http://marc.theaimsgroup.com/?l=ant-dev&m=107349417004602&w=2>.

I am not sure whether you need source="1.5"
fork="true" and executable="......" should be enough.
Just guessing, I did not do any java 1.5 compiles yet.
